+NewPipe contribution guidelines
+===============================
+
+## Crash reporting
+
+Report crashes through the **automated crash report system** of NewPipe.
+This way all the data needed for debugging is included in your bugreport for GitHub.
+You'll see *exactly* what is sent, be able to add **your comments**, and then send it.
+
+## Issue reporting/feature requests
+
+* **Already reported**? Browse the [existing issues](https://github.com/TeamNewPipe/NewPipe/issues) to make sure your issue/feature hasn't been reported/requested.
+* **Already fixed**? Check whether your issue/feature is already fixed/implemented.
+* **Still relevant**? Check if the issue still exists in the latest release/beta version.
+* **Can you fix it**? If you are an Android/Java developer, you are always welcome to fix an issue or implement a feature yourself. PRs welcome! See [Code contribution](#code-contribution) for more info.
+* **Is it in English**? Issues in other languages will be ignored unless someone translates them.
+* **Is it one issue**? Multiple issues require multiple reports, that can be linked to track their statuses.
+* **The template**: Fill it out, everyone wins. Your issue has a chance of getting fixed.
+
+
+## Translation
+
+* NewPipe is translated via [Weblate](https://hosted.weblate.org/projects/newpipe/strings/). Log in there with your GitHub account, or register.
+* Add the language you want to translate if it is not there already: see [How to add a new language](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-add-a-new-language-to-NewPipe) in the wiki.
+
+## Code contribution
+
+### Guidelines
+
+* Stick to NewPipe's *style conventions* of [checkStyle](https://github.com/checkstyle/checkstyle) and [ktlint](https://github.com/pinterest/ktlint). They run each time you build the project.
+* Stick to [F-Droid contribution guidelines](https://f-droid.org/wiki/page/Inclusion_Policy).
+* In particular **do not bring non-free software** (e.g. binary blobs) into the project. Make sure you do not introduce any closed-source library from Google.
+
+### Before starting development
+
+* If you want to help out with an existing bug report or feature request, **leave a comment** on that issue saying you want to try your hand at it.
+* If there is no existing issue for what you want to work on, **open a new one**  describing the changes you are planning to introduce. This gives the team and the community a chance to give **feedback** before you spend time on something that is already in development, should be done differently, or should be avoided completely.
+* Please show **intention to maintain your features** and code after you contribute a PR. Unmaintained code is a hassle for core developers. If you do not intend to maintain features you plan to contribute, please rethink your submission, or clearly state that in the PR description.
+* Create PRs that cover only **one specific issue/solution/bug**. Do not create PRs that are huge monoliths and could have been split into multiple independent contributions.
+* NewPipe uses [NewPipeExtractor](https://github.com/TeamNewPipe/NewPipeExtractor) to fetch data from services. If you need to change something there, you must test your changes in NewPipe. Telling NewPipe to use your extractor version can be accomplished by editing the `app/build.gradle` file: the comments under the "NewPipe libraries" section of `dependencies` will help you out.
+
+### Kotlin in NewPipe
+* NewPipe will remain mostly Java for time being
+* Contributions containing a simple conversion from Java to Kotlin should be avoided. Conversions to Kotlin should only be done if Kotlin actually brings improvements like bug fixes or better performance which are not, or only with much more effort, implementable in Java. The core team sees Java as an easier to learn and generally well adopted programming language.
+
+### Creating a Pull Request (PR)
+
+* Make changes on a **separate branch** with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.
+* Please **test** (compile and run) your code before submitting changes! Ideally, provide test feedback in the PR description. Untested code will **not** be merged!
+* Respond if someone requests changes or otherwise raises issues about your PRs.
+* Try to figure out yourself why builds on our CI fail.
+* Make sure your PR is **up-to-date** with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you must *rebase* your branch on the `dev` branch manually and resolve the conflicts on your own. You can find help [on the wiki](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-merge-a-PR). Doing this makes the maintainers' job way easier.
+
+## IDE setup & building the app
+
+### Basic setup
+
+NewPipe is developed using [Android Studio](https://developer.android.com/studio/). Learn more about how to install it and how it works in the [official documentation](https://developer.android.com/studio/intro). In particular, make sure you have accepted Android Studio's SDK licences. Once Android Studio is ready, setting up the NewPipe project is fairly simple:
+- Clone the NewPipe repository with `git clone https://github.com/TeamNewPipe/NewPipe.git` (or use the link from your own fork, if you want to open a PR).
+- Open the folder you just cloned with Android Studio.
+- Build and run it just like you would do with any other app, with the green triangle in the top bar.
+
+You may find [SonarLint](https://www.sonarlint.org/intellij)'s **inspections** useful in helping you to write good code and prevent bugs.
+
+### checkStyle setup
+
+The [checkStyle](https://github.com/checkstyle/checkstyle) plugin verifies that Java code abides by the project style. It runs automatically each time you build the project. If you want to view errors directly in the editor, instead of having to skim through the build output, you can install an Android Studio plugin:
+- Go to `File -> Settings -> Plugins`, search for `checkstyle` and install `CheckStyle-IDEA`.
+- Go to `File -> Settings -> Tools -> Checkstyle`.
+- Add NewPipe's configuration file by clicking the `+` in the right toolbar of the "Configuration File" list.
+- Under the "Use a local Checkstyle file" bullet, click on `Browse` and pick the file named `checkstyle.xml` in the project's root folder.
+- Enable "Store relative to project location" so that moving the directory around does not create issues.
+- Insert a description in the top bar, then click `Next` and then `Finish`.
+- Activate the configuration file you just added by enabling the checkbox on the left.
+- Click `Ok` and you are done.
+
+### ktlint setup
+
+The [ktlint](https://github.com/pinterest/ktlint) plugin does the same job as checkStyle for Kotlin files. Installing the related plugin is as simple as going to `File -> Settings -> Plugins`, searching for `ktlint` and installing `Ktlint (unofficial)`.
+
+## Communication
+
+* The #newpipe channel on Libera Chat (`ircs://irc.libera.chat:6697/newpipe`) has the core team and other developers in it. [Click here for webchat](https://web.libera.chat/#newpipe)!
+* You can also use a Matrix account to join the NewPipe channel at [#newpipe:libera.chat](https://matrix.to/#/#newpipe:libera.chat). Some convenient clients, available both for phone and desktop, are listed at that link.
+* You can post your suggestions, changes, ideas etc. on either GitHub or IRC.

-### Multi service support
-Generally NewPipe is designed to not only support YouTube, but many more streaming services. However, right now NewPipe is not stable enough to support more than only YouTube. But if all works as planned, NewPipe will get such support by the version 2.0.
+### Supported Services
 
-# Help is always welcome !!!
-Whether it's about ideas, translation, design changes, code cleaning, or real heavy code changes. Help is always welcome.
+NewPipe supports multiple services. Our [docs](https://teamnewpipe.github.io/documentation/) provide more info on how a new service can be added to the app and the extractor. Please get in touch with us if you intend to add a new one. Currently supported services are:
 
+* YouTube
+* SoundCloud \[beta\]
+* media.ccc.de \[beta\]
+* PeerTube instances \[beta\]
+* Bandcamp \[beta\]

+
+## Installation and updates
+You can install NewPipe using one of the following methods:
+ 1. Add our custom repo to F-Droid and install it from there. The instructions are here: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. Download the APK from [GitHub Releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
+ 3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
+ 4. Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
+
+We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other, but not with those installed using method 3. This is due to the same signing key (ours) being used for 1 and 2, but a different signing key (F-Droid's) being used for 3. Building a debug APK using method 4 excludes a key entirely. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app.
+
+In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality breaks and F-Droid doesn't have the latest update yet), we recommend following this procedure:
+1. Back up your data via Settings > Content > Export Database so you keep your history, subscriptions, and playlists
+2. Uninstall NewPipe
+3. Download the APK from the new source and install it
+4. Import the data from step 1 via Settings > Content > Import Database
+

+    explicitly state otherwise, any Contribution intentionally submitted for
+    inclusion in the Work by You to the Licensor shall be under the terms and

+
+<p>THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+    PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR
+    DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS
+    AGREEMENT.</p>
+
+<p><b>1. DEFINITIONS</b></p>
+
+<p>"Contribution" means:</p>
+
+<p class="list">a) in the case of the initial Contributor, the initial
+    code and documentation distributed under this Agreement, and</p>
+<p class="list">b) in the case of each subsequent Contributor:</p>
+<p class="list">i) changes to the Program, and</p>
+<p class="list">ii) additions to the Program;</p>
+<p class="list">where such changes and/or additions to the Program
+    originate from and are distributed by that particular Contributor. A
+    Contribution 'originates' from a Contributor if it was added to the
+    Program by such Contributor itself or anyone acting on such
+    Contributor's behalf. Contributions do not include additions to the
+    Program which: (i) are separate modules of software distributed in
+    conjunction with the Program under their own license agreement, and (ii)
+    are not derivative works of the Program.</p>
+
+<p>"Contributor" means any person or entity that distributes
+    the Program.</p>
+
+<p>"Licensed Patents" mean patent claims licensable by a
+    Contributor which are necessarily infringed by the use or sale of its
+    Contribution alone or when combined with the Program.</p>
+
+<p>"Program" means the Contributions distributed in accordance
+    with this Agreement.</p>
+
+<p>"Recipient" means anyone who receives the Program under
+    this Agreement, including all Contributors.</p>
+
+<p><b>2. GRANT OF RIGHTS</b></p>
+
+<p class="list">a) Subject to the terms of this Agreement, each
+    Contributor hereby grants Recipient a non-exclusive, worldwide,
+    royalty-free copyright license to reproduce, prepare derivative works
+    of, publicly display, publicly perform, distribute and sublicense the
+    Contribution of such Contributor, if any, and such derivative works, in
+    source code and object code form.</p>
+
+<p class="list">b) Subject to the terms of this Agreement, each
+    Contributor hereby grants Recipient a non-exclusive, worldwide,
+    royalty-free patent license under Licensed Patents to make, use, sell,
+    offer to sell, import and otherwise transfer the Contribution of such
+    Contributor, if any, in source code and object code form. This patent
+    license shall apply to the combination of the Contribution and the
+    Program if, at the time the Contribution is added by the Contributor,
+    such addition of the Contribution causes such combination to be covered
+    by the Licensed Patents. The patent license shall not apply to any other
+    combinations which include the Contribution. No hardware per se is
+    licensed hereunder.</p>
+
+<p class="list">c) Recipient understands that although each Contributor
+    grants the licenses to its Contributions set forth herein, no assurances
+    are provided by any Contributor that the Program does not infringe the
+    patent or other intellectual property rights of any other entity. Each
+    Contributor disclaims any liability to Recipient for claims brought by
+    any other entity based on infringement of intellectual property rights
+    or otherwise. As a condition to exercising the rights and licenses
+    granted hereunder, each Recipient hereby assumes sole responsibility to
+    secure any other intellectual property rights needed, if any. For
+    example, if a third party patent license is required to allow Recipient
+    to distribute the Program, it is Recipient's responsibility to acquire
+    that license before distributing the Program.</p>
+
+<p class="list">d) Each Contributor represents that to its knowledge it
+    has sufficient copyright rights in its Contribution, if any, to grant
+    the copyright license set forth in this Agreement.</p>
+
+<p><b>3. REQUIREMENTS</b></p>
+
+<p>A Contributor may choose to distribute the Program in object code
+    form under its own license agreement, provided that:</p>
+
+<p class="list">a) it complies with the terms and conditions of this
+    Agreement; and</p>
+
+<p class="list">b) its license agreement:</p>
+
+<p class="list">i) effectively disclaims on behalf of all Contributors
+    all warranties and conditions, express and implied, including warranties
+    or conditions of title and non-infringement, and implied warranties or
+    conditions of merchantability and fitness for a particular purpose;</p>
+
+<p class="list">ii) effectively excludes on behalf of all Contributors
+    all liability for damages, including direct, indirect, special,
+    incidental and consequential damages, such as lost profits;</p>
+
+<p class="list">iii) states that any provisions which differ from this
+    Agreement are offered by that Contributor alone and not by any other
+    party; and</p>
+
+<p class="list">iv) states that source code for the Program is available
+    from such Contributor, and informs licensees how to obtain it in a
+    reasonable manner on or through a medium customarily used for software
+    exchange.</p>
+
+<p>When the Program is made available in source code form:</p>
+
+<p class="list">a) it must be made available under this Agreement; and</p>
+
+<p class="list">b) a copy of this Agreement must be included with each
+    copy of the Program.</p>
+
+<p>Contributors may not remove or alter any copyright notices contained
+    within the Program.</p>
+
+<p>Each Contributor must identify itself as the originator of its
+    Contribution, if any, in a manner that reasonably allows subsequent
+    Recipients to identify the originator of the Contribution.</p>
+
+<p><b>4. COMMERCIAL DISTRIBUTION</b></p>
+
+<p>Commercial distributors of software may accept certain
+    responsibilities with respect to end users, business partners and the
+    like. While this license is intended to facilitate the commercial use of
+    the Program, the Contributor who includes the Program in a commercial
+    product offering should do so in a manner which does not create
+    potential liability for other Contributors. Therefore, if a Contributor
+    includes the Program in a commercial product offering, such Contributor
+    ("Commercial Contributor") hereby agrees to defend and
+    indemnify every other Contributor ("Indemnified Contributor")
+    against any losses, damages and costs (collectively "Losses")
+    arising from claims, lawsuits and other legal actions brought by a third
+    party against the Indemnified Contributor to the extent caused by the
+    acts or omissions of such Commercial Contributor in connection with its
+    distribution of the Program in a commercial product offering. The
+    obligations in this section do not apply to any claims or Losses
+    relating to any actual or alleged intellectual property infringement. In
+    order to qualify, an Indemnified Contributor must: a) promptly notify
+    the Commercial Contributor in writing of such claim, and b) allow the
+    Commercial Contributor to control, and cooperate with the Commercial
+    Contributor in, the defense and any related settlement negotiations. The
+    Indemnified Contributor may participate in any such claim at its own
+    expense.</p>
+
+<p>For example, a Contributor might include the Program in a commercial
+    product offering, Product X. That Contributor is then a Commercial
+    Contributor. If that Commercial Contributor then makes performance
+    claims, or offers warranties related to Product X, those performance
+    claims and warranties are such Commercial Contributor's responsibility
+    alone. Under this section, the Commercial Contributor would have to
+    defend claims against the other Contributors related to those
+    performance claims and warranties, and if a court requires any other
+    Contributor to pay any damages as a result, the Commercial Contributor
+    must pay those damages.</p>
+
+<p><b>5. NO WARRANTY</b></p>
+
+<p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+    PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS
+    OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION,
+    ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+    OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+    responsible for determining the appropriateness of using and
+    distributing the Program and assumes all risks associated with its
+    exercise of rights under this Agreement , including but not limited to
+    the risks and costs of program errors, compliance with applicable laws,
+    damage to or loss of data, programs or equipment, and unavailability or
+    interruption of operations.</p>
+
+<p><b>6. DISCLAIMER OF LIABILITY</b></p>
+
+<p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT
+    NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+    INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+    WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+    LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+    NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+    DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+    HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.</p>
+
+<p><b>7. GENERAL</b></p>
+
+<p>If any provision of this Agreement is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this Agreement, and without further action
+    by the parties hereto, such provision shall be reformed to the minimum
+    extent necessary to make such provision valid and enforceable.</p>
+
+<p>If Recipient institutes patent litigation against any entity
+    (including a cross-claim or counterclaim in a lawsuit) alleging that the
+    Program itself (excluding combinations of the Program with other
+    software or hardware) infringes such Recipient's patent(s), then such
+    Recipient's rights granted under Section 2(b) shall terminate as of the
+    date such litigation is filed.</p>
+
+<p>All Recipient's rights under this Agreement shall terminate if it
+    fails to comply with any of the material terms or conditions of this
+    Agreement and does not cure such failure in a reasonable period of time
+    after becoming aware of such noncompliance. If all Recipient's rights
+    under this Agreement terminate, Recipient agrees to cease use and
+    distribution of the Program as soon as reasonably practicable. However,
+    Recipient's obligations under this Agreement and any licenses granted by
+    Recipient relating to the Program shall continue and survive.</p>
+
+<p>Everyone is permitted to copy and distribute copies of this
+    Agreement, but in order to avoid inconsistency the Agreement is
+    copyrighted and may only be modified in the following manner. The
+    Agreement Steward reserves the right to publish new versions (including
+    revisions) of this Agreement from time to time. No one other than the
+    Agreement Steward has the right to modify this Agreement. The Eclipse
+    Foundation is the initial Agreement Steward. The Eclipse Foundation may
+    assign the responsibility to serve as the Agreement Steward to a
+    suitable separate entity. Each new version of the Agreement will be
+    given a distinguishing version number. The Program (including
+    Contributions) may always be distributed subject to the version of the
+    Agreement under which it was received. In addition, after a new version
+    of the Agreement is published, Contributor may elect to distribute the
+    Program (including its Contributions) under the new version. Except as
+    expressly stated in Sections 2(a) and 2(b) above, Recipient receives no
+    rights or licenses to the intellectual property of any Contributor under
+    this Agreement, whether expressly, by implication, estoppel or
+    otherwise. All rights in the Program not expressly granted under this
+    Agreement are reserved.</p>
+
+<p>This Agreement is governed by the laws of the State of New York and
+    the intellectual property laws of the United States of America. No party
+    to this Agreement will bring a legal action under this Agreement more
+    than one year after the cause of action arose. Each party waives its
+    rights to a jury trial in any resulting litigation.</p>

+
+<p>The GNU General Public License is a free, copyleft license for

+
+<p>The licenses for most software and other practical works are designed

+
+<p>When we speak of free software, we are referring to freedom, not

+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.</p>
+
+<p>To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.</p>
+
+<p>For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.</p>
+
+<p>Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.</p>
+
+<p>For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.</p>
+
+<p>Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.</p>
+
+<p>Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.</p>
+
+<p>The precise terms and conditions for copying, distribution and
+modification follow.</p>
+
+<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
+
+<h4><a name="section0"></a>0. Definitions.</h4>
+
+<p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>
+
+<p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.</p>
+ 
+<p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as &ldquo;you&rdquo;.  &ldquo;Licensees&rdquo; and
+&ldquo;recipients&rdquo; may be individuals or organizations.</p>
+
+<p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a &ldquo;modified version&rdquo; of the
+earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
+
+<p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
+on the Program.</p>
+
+<p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.</p>
+
+<p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.</p>
+
+<p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.</p>
+
+<h4><a name="section1"></a>1. Source Code.</h4>
+
+<p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
+for making modifications to it.  &ldquo;Object code&rdquo; means any non-source
+form of a work.</p>
+
+<p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.</p>
+
+<p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+&ldquo;Major Component&rdquo;, in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.</p>
+
+<p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.</p>
+
+<p>The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.</p>
+
+<p>The Corresponding Source for a work in source code form is that
+same work.</p>
+
+<h4><a name="section2"></a>2. Basic Permissions.</h4>
+
+<p>All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.</p>
+
+<p>You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.</p>
+
+<p>Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.</p>
+
+<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
+
+<p>No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.</p>
+
+<p>When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.</p>
+
+<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
+
+<p>You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.</p>
+
+<p>You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.</p>
+
+<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
+
+<p>You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:</p>
+
+<ul>
+<li>a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.</li>
+
+<li>b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    &ldquo;keep intact all notices&rdquo;.</li>
+
+<li>c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.</li>
+
+<li>d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.</li>
+</ul>
+
+<p>A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+&ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.</p>
+
+<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
+
+<p>You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:</p>
+
+<ul>
+<li>a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.</li>
+
+<li>b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.</li>
+
+<li>c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.</li>
+
+<li>d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.</li>
+
+<li>e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.</li>
+</ul>
+
+<p>A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.</p>
+
+<p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, &ldquo;normally used&rdquo; refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.</p>
+
+<p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.</p>
+
+<p>If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).</p>
+
+<p>The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.</p>
+
+<p>Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.</p>
+
+<h4><a name="section7"></a>7. Additional Terms.</h4>
+
+<p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.</p>
+
+<p>When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.</p>
+
+<p>Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:</p>
+
+<ul>
+<li>a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or</li>
+
+<li>b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or</li>
+
+<li>c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or</li>
+
+<li>d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or</li>
+
+<li>e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or</li>
+
+<li>f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.</li>
+</ul>
+
+<p>All other non-permissive additional terms are considered &ldquo;further
+restrictions&rdquo; within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.</p>
+
+<p>If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.</p>
+
+<p>Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.</p>
+
+<h4><a name="section8"></a>8. Termination.</h4>
+
+<p>You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).</p>
+
+<p>However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.</p>
+
+<p>Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.</p>
+
+<p>Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.</p>
+
+<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
+
+<p>You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.</p>
+
+<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
+
+<p>Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.</p>
+
+<p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.</p>
+
+<p>You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.</p>
+
+<h4><a name="section11"></a>11. Patents.</h4>
+
+<p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
+
+<p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, &ldquo;control&rdquo; includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.</p>
+
+<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.</p>
+
+<p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To &ldquo;grant&rdquo; such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.</p>
+
+<p>If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  &ldquo;Knowingly relying&rdquo; means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.</p>
+  
+<p>If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.</p>
+
+<p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.</p>
+
+<p>Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.</p>
+
+<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
+
+<p>If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.</p>
+
+<h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
+
+<p>Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.</p>
+
+<h4><a name="section14"></a>14. Revised Versions of this License.</h4>
+
+<p>The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.</p>
+
+<p>Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License &ldquo;or any later version&rdquo; applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.</p>

+<ol type="a">
+    <li><p>under intellectual property rights (other than patent or trademark) Licensable by such
+        Contributor to use, reproduce, make available, modify, display, perform, distribute, and
+        otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or

+    <li><p>under Patent Claims of such Contributor to make, use, sell, offer for sale, have made,
+        import, and otherwise transfer either its Contributions or its Contributor Version.</p></li>
+</ol>
+<h3 id="effective-date">2.2. Effective Date</h3>
+<p>The licenses granted in Section&nbsp;2.1 with respect to any Contribution become effective for
+    each Contribution on the date the Contributor first distributes such Contribution.</p>
+<h3 id="limitations-on-grant-scope">2.3. Limitations on Grant Scope</h3>
+<p>The licenses granted in this Section&nbsp;2 are the only rights granted under this License. No
+    additional rights or licenses will be implied from the distribution or licensing of Covered
+    Software under this License. Notwithstanding Section&nbsp;2.1(b) above, no patent license is
+    granted by a Contributor:</p>
+<ol type="a">
+    <li><p>for any code that a Contributor has removed from Covered Software; or</p></li>
+    <li><p>for infringements caused by: (i) Your and any other third party’s modifications of
+        Covered Software, or (ii) the combination of its Contributions with other software (except
+        as part of its Contributor Version); or</p></li>
+    <li><p>under Patent Claims infringed by Covered Software in the absence of its
+        Contributions.</p></li>
+</ol>
+<p>This License does not grant any rights in the trademarks, service marks, or logos of any
+    Contributor (except as may be necessary to comply with the notice requirements in Section&nbsp;3.4).</p>
+<h3 id="subsequent-licenses">2.4. Subsequent Licenses</h3>
+<p>No Contributor makes additional grants as a result of Your choice to distribute the Covered
+    Software under a subsequent version of this License (see Section&nbsp;10.2) or under the terms
+    of a Secondary License (if permitted under the terms of Section&nbsp;3.3).</p>
+<h3 id="representation">2.5. Representation</h3>
+<p>Each Contributor represents that the Contributor believes its Contributions are its original
+    creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by
+    this License.</p>
+<h3 id="fair-use">2.6. Fair Use</h3>
+<p>This License is not intended to limit any rights You have under applicable copyright doctrines of
+    fair use, fair dealing, or other equivalents.</p>
+<h3 id="conditions">2.7. Conditions</h3>
+<p>Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section&nbsp;2.1.</p>
+<h2 id="responsibilities">3. Responsibilities</h2>
+<h3 id="distribution-of-source-form">3.1. Distribution of Source Form</h3>
+<p>All distribution of Covered Software in Source Code Form, including any Modifications that You
+    create or to which You contribute, must be under the terms of this License. You must inform
+    recipients that the Source Code Form of the Covered Software is governed by the terms of this
+    License, and how they can obtain a copy of this License. You may not attempt to alter or
+    restrict the recipients’ rights in the Source Code Form.</p>
+<h3 id="distribution-of-executable-form">3.2. Distribution of Executable Form</h3>
+<p>If You distribute Covered Software in Executable Form then:</p>
+<ol type="a">
+    <li><p>such Covered Software must also be made available in Source Code Form, as described in
+        Section&nbsp;3.1, and You must inform recipients of the Executable Form how they can obtain
+        a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more
+        than the cost of distribution to the recipient; and</p></li>
+    <li><p>You may distribute such Executable Form under the terms of this License, or sublicense it
+        under different terms, provided that the license for the Executable Form does not attempt to
+        limit or alter the recipients’ rights in the Source Code Form under this License.</p></li>
+</ol>
+<h3 id="distribution-of-a-larger-work">3.3. Distribution of a Larger Work</h3>
+<p>You may create and distribute a Larger Work under terms of Your choice, provided that You also
+    comply with the requirements of this License for the Covered Software. If the Larger Work is a
+    combination of Covered Software with a work governed by one or more Secondary Licenses, and the
+    Covered Software is not Incompatible With Secondary Licenses, this License permits You to
+    additionally distribute such Covered Software under the terms of such Secondary License(s), so
+    that the recipient of the Larger Work may, at their option, further distribute the Covered
+    Software under the terms of either this License or such Secondary License(s).</p>
+<h3 id="notices">3.4. Notices</h3>
+<p>You may not remove or alter the substance of any license notices (including copyright notices,
+    patent notices, disclaimers of warranty, or limitations of liability) contained within the
+    Source Code Form of the Covered Software, except that You may alter any license notices to the
+    extent required to remedy known factual inaccuracies.</p>
+<h3 id="application-of-additional-terms">3.5. Application of Additional Terms</h3>
+<p>You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability
+    obligations to one or more recipients of Covered Software. However, You may do so only on Your
+    own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any
+    such warranty, support, indemnity, or liability obligation is offered by You alone, and You
+    hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a
+    result of warranty, support, indemnity or liability terms You offer. You may include additional
+    disclaimers of warranty and limitations of liability specific to any jurisdiction.</p>
+<h2 id="inability-to-comply-due-to-statute-or-regulation">4. Inability to Comply Due to Statute or
+    Regulation</h2>
+<p>If it is impossible for You to comply with any of the terms of this License with respect to some
+    or all of the Covered Software due to statute, judicial order, or regulation then You must: (a)
+    comply with the terms of this License to the maximum extent possible; and (b) describe the
+    limitations and the code they affect. Such description must be placed in a text file included
+    with all distributions of the Covered Software under this License. Except to the extent
+    prohibited by statute or regulation, such description must be sufficiently detailed for a
+    recipient of ordinary skill to be able to understand it.</p>
+<h2 id="termination">5. Termination</h2>
+<p>5.1. The rights granted under this License will terminate automatically if You fail to comply
+    with any of its terms. However, if You become compliant, then the rights granted under this
+    License from a particular Contributor are reinstated (a) provisionally, unless and until such
+    Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such
+    Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days
+    after You have come back into compliance. Moreover, Your grants from a particular Contributor
+    are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by
+    some reasonable means, this is the first time You have received notice of non-compliance with
+    this License from such Contributor, and You become compliant prior to 30 days after Your receipt
+    of the notice.</p>
+<p>5.2. If You initiate litigation against any entity by asserting a patent infringement claim
+    (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a
+    Contributor Version directly or indirectly infringes any patent, then the rights granted to You
+    by any and all Contributors for the Covered Software under Section&nbsp;2.1 of this License
+    shall terminate.</p>
+<p>5.3. In the event of termination under Sections&nbsp;5.1 or 5.2 above, all end user license
+    agreements (excluding distributors and resellers) which have been validly granted by You or Your
+    distributors under this License prior to termination shall survive termination.</p>
+<h2 id="disclaimer-of-warranty">6. Disclaimer of Warranty</h2>
+<p><em>Covered Software is provided under this License on an “as is” basis, without warranty of any
+    kind, either expressed, implied, or statutory, including, without limitation, warranties that
+    the Covered Software is free of defects, merchantable, fit for a particular purpose or
+    non-infringing. The entire risk as to the quality and performance of the Covered Software is
+    with You. Should any Covered Software prove defective in any respect, You (not any Contributor)
+    assume the cost of any necessary servicing, repair, or correction. This disclaimer of warranty
+    constitutes an essential part of this License. No use of any Covered Software is authorized
+    under this License except under this disclaimer.</em></p>
+<h2 id="limitation-of-liability">7. Limitation of Liability</h2>
+<p><em>Under no circumstances and under no legal theory, whether tort (including negligence),
+    contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as
+    permitted above, be liable to You for any direct, indirect, special, incidental, or
+    consequential damages of any character including, without limitation, damages for lost profits,
+    loss of goodwill, work stoppage, computer failure or malfunction, or any and all other
+    commercial damages or losses, even if such party shall have been informed of the possibility of
+    such damages. This limitation of liability shall not apply to liability for death or personal
+    injury resulting from such party’s negligence to the extent applicable law prohibits such
+    limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or
+    consequential damages, so this exclusion and limitation may not apply to You.</em></p>
+<h2 id="litigation">8. Litigation</h2>
+<p>Any litigation relating to this License may be brought only in the courts of a jurisdiction where
+    the defendant maintains its principal place of business and such litigation shall be governed by
+    laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this
+    Section shall prevent a party’s ability to bring cross-claims or counter-claims.</p>
+<h2 id="miscellaneous">9. Miscellaneous</h2>
+<p>This License represents the complete agreement concerning the subject matter hereof. If any
+    provision of this License is held to be unenforceable, such provision shall be reformed only to
+    the extent necessary to make it enforceable. Any law or regulation which provides that the
+    language of a contract shall be construed against the drafter shall not be used to construe this
+    License against a Contributor.</p>
+<h2 id="versions-of-the-license">10. Versions of the License</h2>
+<h3 id="new-versions">10.1. New Versions</h3>
+<p>Mozilla Foundation is the license steward. Except as provided in Section&nbsp;10.3, no one other
+    than the license steward has the right to modify or publish new versions of this License. Each
+    version will be given a distinguishing version number.</p>
+<h3 id="effect-of-new-versions">10.2. Effect of New Versions</h3>
+<p>You may distribute the Covered Software under the terms of the version of the License under which
+    You originally received the Covered Software, or under the terms of any subsequent version
+    published by the license steward.</p>
+<h3 id="modified-versions">10.3. Modified Versions</h3>
+<p>If you create software not governed by this License, and you want to create a new license for
+    such software, you may create and use a modified version of this License if you rename the
+    license and remove any references to the name of the license steward (except to note that such
+    modified license differs from this License).</p>
+<h3 id="distributing-source-code-form-that-is-incompatible-with-secondary-licenses">10.4.
+    Distributing Source Code Form that is Incompatible With Secondary Licenses</h3>
+<p>If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under
+    the terms of this version of the License, the notice described in Exhibit B of this License must
+    be attached.</p>
+<h2 id="exhibit-a---source-code-form-license-notice">Exhibit A - Source Code Form License
+    Notice</h2>
