-Contributing code to Matrix
-===========================
-
-Everyone is welcome to contribute code to Matrix
-(https://github.com/matrix-org), provided that they are willing to license
-their contributions under the same license as the project itself. We follow a
-simple 'inbound=outbound' model for contributions: the act of submitting an
-'inbound' contribution means that the contributor agrees to license the code
-under the same terms as the project's overall 'outbound' license - in our
-case, this is almost always Apache Software License v2 (see LICENSE).
-
-How to contribute
-~~~~~~~~~~~~~~~~~
-
-The preferred and easiest way to contribute changes to Matrix is to fork the
-relevant project on github, and then create a pull request to ask us to pull
-your changes into our repo
-(https://help.github.com/articles/using-pull-requests/)
-
-**The single biggest thing you need to know is: please base your changes on
-the develop branch - /not/ master.**
-
-We use the master branch to track the most recent release, so that folks who
-blindly clone the repo and automatically check out master get something that
-works. Develop is the unstable branch where all the development actually
-happens: the workflow is that contributors should fork the develop branch to
-make a 'feature' branch for a particular contribution, and then make a pull
-request to merge this back into the matrix.org 'official' develop branch. We
-use github's pull request workflow to review the contribution, and either ask
-you to make any refinements needed or merge it and make them ourselves. The
-changes will then land on master when we next do a release.
-
-We use `Jenkins <http://matrix.org/jenkins>`_ and 
-`Travis <https://travis-ci.org/matrix-org/synapse>`_ for continuous
-integration. All pull requests to synapse get automatically tested by Travis; 
-the Jenkins builds require an adminstrator to start them. If your change 
-breaks the build, this will be shown in github, so please keep an eye on the 
-pull request for feedback.
-
-Code style
-~~~~~~~~~~
-
-All Matrix projects have a well-defined code-style - and sometimes we've even
-got as far as documenting it... For instance, synapse's code style doc lives
-at https://github.com/matrix-org/synapse/tree/master/docs/code_style.rst.
-
-Please ensure your changes match the cosmetic style of the existing project,
-and **never** mix cosmetic and functional changes in the same commit, as it
-makes it horribly hard to review otherwise.
-
-Attribution
-~~~~~~~~~~~
-
-Everyone who contributes anything to Matrix is welcome to be listed in the
-AUTHORS.rst file for the project in question. Please feel free to include a
-change to AUTHORS.rst in your pull request to list yourself and a short
-description of the area(s) you've worked on. Also, we sometimes have swag to
-give away to contributors - if you feel that Matrix-branded apparel is missing
-from your life, please mail us your shipping address to matrix at matrix.org and we'll try to fix it :)
-
-Sign off
-~~~~~~~~
-
-In order to have a concrete record that your contribution is intentional

 Upgrading Synapse
 =================
 
-Before upgrading check if any special steps are required to upgrade from the
-what you currently have installed to current version of synapse. The extra
-instructions that may be required are listed later in this document.
+This document has moved to the `Synapse documentation website <https://matrix-org.github.io/synapse/latest/upgrade>`_.
+Please update your links.
 
-1. If synapse was installed in a virtualenv then active that virtualenv before
-   upgrading. If synapse is installed in a virtualenv in ``~/.synapse/`` then
-   run:
-
-   .. code:: bash
-
-       source ~/.synapse/bin/activate
-
-2. If synapse was installed using pip then upgrade to the latest version by
-   running:
-
-   .. code:: bash
-
-       pip install --upgrade --process-dependency-links https://github.com/matrix-org/synapse/tarball/master
-
-       # restart synapse
-       synctl restart
-
-
-   If synapse was installed using git then upgrade to the latest version by
-   running:
-
-   .. code:: bash
-
-       # Pull the latest version of the master branch.
-       git pull
-       # Update the versions of synapse's python dependencies.
-       python synapse/python_dependencies.py | xargs pip install --upgrade
-
-       # restart synapse
-       ./synctl restart
-
-
-To check whether your update was sucessful, you can check the Server header
-returned by the Client-Server API:
-
-.. code:: bash
-
-    # replace <host.name> with the hostname of your synapse homeserver.
-    # You may need to specify a port (eg, :8448) if your server is not
-    # configured on port 443.
-    curl -kv https://<host.name>/_matrix/client/versions 2>&1 | grep "Server:"
-
-Upgrading to $NEXT_VERSION
-====================
-
-This release expands the anonymous usage stats sent if the opt-in
-``report_stats`` configuration is set to ``true``. We now capture RSS memory 
-and cpu use at a very coarse level. This requires administrators to install
-the optional ``psutil`` python module.
-
-We would appreciate it if you could assist by ensuring this module is available
-and ``report_stats`` is enabled. This will let us see if performance changes to
-synapse are having an impact to the general community.
-
-Upgrading to v0.15.0
-====================
-
-If you want to use the new URL previewing API (/_matrix/media/r0/preview_url)
-then you have to explicitly enable it in the config and update your dependencies
-dependencies.  See README.rst for details.
-
-
-Upgrading to v0.11.0
-====================
-
-This release includes the option to send anonymous usage stats to matrix.org,
-and requires that administrators explictly opt in or out by setting the
-``report_stats`` option to either ``true`` or ``false``.
-
-We would really appreciate it if you could help our project out by reporting
-anonymized usage statistics from your homeserver. Only very basic aggregate
-data (e.g. number of users) will be reported, but it helps us to track the
-growth of the Matrix community, and helps us to make Matrix a success, as well
-as to convince other networks that they should peer with us.
-
-
-Upgrading to v0.9.0
-===================
-
-Application services have had a breaking API change in this version.
-
-They can no longer register themselves with a home server using the AS HTTP API. This
-decision was made because a compromised application service with free reign to register
-any regex in effect grants full read/write access to the home server if a regex of ``.*``
-is used. An attack where a compromised AS re-registers itself with ``.*`` was deemed too
-big of a security risk to ignore, and so the ability to register with the HS remotely has
-been removed.
-
-It has been replaced by specifying a list of application service registrations in
-``homeserver.yaml``::
-
-  app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
-
-Where ``registration-01.yaml`` looks like::
-
-  url: <String>  # e.g. "https://my.application.service.com"
-  as_token: <String>
-  hs_token: <String>
-  sender_localpart: <String>  # This is a new field which denotes the user_id localpart when using the AS token
-  namespaces:
-    users:
-      - exclusive: <Boolean>
-        regex: <String>  # e.g. "@prefix_.*"
-    aliases:
-      - exclusive: <Boolean>
-        regex: <String>
-    rooms:
-      - exclusive: <Boolean>
-        regex: <String>
-
-Upgrading to v0.8.0
-===================
-
-Servers which use captchas will need to add their public key to::
-
-  static/client/register/register_config.js
-
-    window.matrixRegistrationConfig = {
-        recaptcha_public_key: "YOUR_PUBLIC_KEY"
-    };
-
-This is required in order to support registration fallback (typically used on
-mobile devices).
-
-
-Upgrading to v0.7.0
-===================
-
-New dependencies are:
-
-- pydenticon
-- simplejson
-- syutil
-- matrix-angular-sdk
-
-To pull in these dependencies in a virtual env, run::
-
-    python synapse/python_dependencies.py | xargs -n 1 pip install
-
-Upgrading to v0.6.0
-===================
-
-To pull in new dependencies, run::
-
-    python setup.py develop --user
-
-This update includes a change to the database schema. To upgrade you first need
-to upgrade the database by running::
-
-    python scripts/upgrade_db_to_v0.6.0.py <db> <server_name> <signing_key>
-
-Where `<db>` is the location of the database, `<server_name>` is the
-server name as specified in the synapse configuration, and `<signing_key>` is
-the location of the signing key as specified in the synapse configuration.
-
-This may take some time to complete. Failures of signatures and content hashes
-can safely be ignored.
-
-
-Upgrading to v0.5.1
-===================
-
-Depending on precisely when you installed v0.5.0 you may have ended up with
-a stale release of the reference matrix webclient installed as a python module.
-To uninstall it and ensure you are depending on the latest module, please run::
-
-    $ pip uninstall syweb
-
-Upgrading to v0.5.0
-===================
-
-The webclient has been split out into a seperate repository/pacakage in this
-release. Before you restart your homeserver you will need to pull in the
-webclient package by running::
-
-  python setup.py develop --user
-
-This release completely changes the database schema and so requires upgrading
-it before starting the new version of the homeserver.
-
-The script "database-prepare-for-0.5.0.sh" should be used to upgrade the
-database. This will save all user information, such as logins and profiles,
-but will otherwise purge the database. This includes messages, which
-rooms the home server was a member of and room alias mappings.
-
-If you would like to keep your history, please take a copy of your database
-file and ask for help in #matrix:matrix.org. The upgrade process is,
-unfortunately, non trivial and requires human intervention to resolve any
-resulting conflicts during the upgrade process.
-
-Before running the command the homeserver should be first completely
-shutdown. To run it, simply specify the location of the database, e.g.:
-
-  ./scripts/database-prepare-for-0.5.0.sh "homeserver.db"
-
-Once this has successfully completed it will be safe to restart the
-homeserver. You may notice that the homeserver takes a few seconds longer to
-restart than usual as it reinitializes the database.
-
-On startup of the new version, users can either rejoin remote rooms using room
-aliases or by being reinvited. Alternatively, if any other homeserver sends a
-message to a room that the homeserver was previously in the local HS will
-automatically rejoin the room.
-
-Upgrading to v0.4.0
-===================
-
-This release needs an updated syutil version. Run::
-
-    python setup.py develop
-
-You will also need to upgrade your configuration as the signing key format has
-changed. Run::
-
-    python -m synapse.app.homeserver --config-path <CONFIG> --generate-config
-
-
-Upgrading to v0.3.0
-===================
-
-This registration API now closely matches the login API. This introduces a bit
-more backwards and forwards between the HS and the client, but this improves
-the overall flexibility of the API. You can now GET on /register to retrieve a list
-of valid registration flows. Upon choosing one, they are submitted in the same
-way as login, e.g::
-
-  {
-    type: m.login.password,
-    user: foo,
-    password: bar
-  }
-
-The default HS supports 2 flows, with and without Identity Server email
-authentication. Enabling captcha on the HS will add in an extra step to all
-flows: ``m.login.recaptcha`` which must be completed before you can transition
-to the next stage. There is a new login type: ``m.login.email.identity`` which
-contains the ``threepidCreds`` key which were previously sent in the original
-register request. For more information on this, see the specification.
-
-Web Client
-----------
-
-The VoIP specification has changed between v0.2.0 and v0.3.0. Users should
-refresh any browser tabs to get the latest web client code. Users on
-v0.2.0 of the web client will not be able to call those on v0.3.0 and
-vice versa.
-
-
-Upgrading to v0.2.0
-===================
-
-The home server now requires setting up of SSL config before it can run. To
-automatically generate default config use::
-
-    $ python synapse/app/homeserver.py \
-        --server-name machine.my.domain.name \
-        --bind-port 8448 \
-        --config-path homeserver.config \
-        --generate-config
-
-This config can be edited if desired, for example to specify a different SSL
-certificate to use. Once done you can run the home server using::
-
-    $ python synapse/app/homeserver.py --config-path homeserver.config
-
-See the README.rst for more information.
-
-Also note that some config options have been renamed, including:
-
-- "host" to "server-name"
-- "database" to "database-path"
-- "port" to "bind-port" and "unsecure-port"
-
-
-Upgrading to v0.0.1
-===================
-
-This release completely changes the database schema and so requires upgrading
-it before starting the new version of the homeserver.
-
-The script "database-prepare-for-0.0.1.sh" should be used to upgrade the
-database. This will save all user information, such as logins and profiles,
-but will otherwise purge the database. This includes messages, which
-rooms the home server was a member of and room alias mappings.
-
-Before running the command the homeserver should be first completely
-shutdown. To run it, simply specify the location of the database, e.g.:
-
-  ./scripts/database-prepare-for-0.0.1.sh "homeserver.db"
-
-Once this has successfully completed it will be safe to restart the
-homeserver. You may notice that the homeserver takes a few seconds longer to
-restart than usual as it reinitializes the database.
-
-On startup of the new version, users can either rejoin remote rooms using room
-aliases or by being reinvited. Alternatively, if any other homeserver sends a
-message to a room that the homeserver was previously in the local HS will
-automatically rejoin the room.
