-# Contributing code to Synapse
+# Welcome to Synapse
 
-Everyone is welcome to contribute code to [matrix.org
-projects](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](LICENSE)).
-
-## How to contribute
-
-The preferred and easiest way to contribute changes is to fork the relevant
-project on github, and then [create a pull request](
-https://help.github.com/articles/using-pull-requests/) to ask us to pull your
-changes into our repo.
-
-Some other points to follow:
-
- * Please base your changes on the `develop` branch.
-
- * Please follow the [code style requirements](#code-style).
-
- * Please include a [changelog entry](#changelog) with each PR.
-
- * Please [sign off](#sign-off) your contribution.
-
- * Please keep an eye on the pull request for feedback from the [continuous
-   integration system](#continuous-integration-and-testing) and try to fix any
-   errors that come up.
-
- * If you need to [update your PR](#updating-your-pull-request), just add new
-   commits to your branch rather than rebasing.
-
-## Code style
-
-Synapse's code style is documented [here](docs/code_style.md). Please follow
-it, including the conventions for the [sample configuration
-file](docs/code_style.md#configuration-file-format).
-
-Many of the conventions are enforced by scripts which are run as part of the
-[continuous integration system](#continuous-integration-and-testing). To help
-check if you have followed the code style, you can run `scripts-dev/lint.sh`
-locally. You'll need python 3.6 or later, and to install a number of tools:
-
-```
-# Install the dependencies
-pip install -e ".[lint,mypy]"
-
-# Run the linter script
-./scripts-dev/lint.sh
-```
-
-**Note that the script does not just test/check, but also reformats code, so you
-may wish to ensure any new code is committed first**.
-
-By default, this script checks all files and can take some time; if you alter
-only certain files, you might wish to specify paths as arguments to reduce the
-run-time:
-
-```
-./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
-```
-
-You can also provide the `-d` option, which will lint the files that have been
-changed since the last git commit. This will often be significantly faster than
-linting the whole codebase.
-
-Before pushing new changes, ensure they don't produce linting errors. Commit any
-files that were corrected.
-
-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.
-
-## Changelog
-
-All changes, even minor ones, need a corresponding changelog / newsfragment
-entry. These are managed by [Towncrier](https://github.com/hawkowl/towncrier).
-
-To create a changelog entry, make a new file in the `changelog.d` directory named
-in the format of `PRnumber.type`. The type can be one of the following:
-
-* `feature`
-* `bugfix`
-* `docker` (for updates to the Docker image)
-* `doc` (for updates to the documentation)
-* `removal` (also used for deprecations)
-* `misc` (for internal-only changes)
-
-This file will become part of our [changelog](
-https://github.com/matrix-org/synapse/blob/master/CHANGES.md) at the next
-release, so the content of the file should be a short description of your
-change in the same style as the rest of the changelog. The file can contain Markdown
-formatting, and should end with a full stop (.) or an exclamation mark (!) for
-consistency.
-
-Adding credits to the changelog is encouraged, we value your
-contributions and would like to have you shouted out in the release notes!
-
-For example, a fix in PR #1234 would have its changelog entry in
-`changelog.d/1234.bugfix`, and contain content like:
-
-> The security levels of Florbs are now validated when received
-> via the `/federation/florb` endpoint. Contributed by Jane Matrix.
-
-If there are multiple pull requests involved in a single bugfix/feature/etc,
-then the content for each `changelog.d` file should be the same. Towncrier will
-merge the matching files together into a single changelog entry when we come to
-release.
-
-### How do I know what to call the changelog file before I create the PR?
-
-Obviously, you don't know if you should call your newsfile
-`1234.bugfix` or `5678.bugfix` until you create the PR, which leads to a
-chicken-and-egg problem.
-
-There are two options for solving this:
-
- 1. Open the PR without a changelog file, see what number you got, and *then*
-    add the changelog file to your branch (see [Updating your pull
-    request](#updating-your-pull-request)), or:
-
- 1. Look at the [list of all
-    issues/PRs](https://github.com/matrix-org/synapse/issues?q=), add one to the
-    highest number you see, and quickly open the PR before somebody else claims
-    your number.
-
-    [This
-    script](https://github.com/richvdh/scripts/blob/master/next_github_number.sh)
-    might be helpful if you find yourself doing this a lot.
-
-Sorry, we know it's a bit fiddly, but it's *really* helpful for us when we come
-to put together a release!
-
-### Debian changelog
-
-Changes which affect the debian packaging files (in `debian`) are an
-exception to the rule that all changes require a `changelog.d` file.
-
-In this case, you will need to add an entry to the debian changelog for the
-next release. For this, run the following command:
-
-```
-dch
-```
-
-This will make up a new version number (if there isn't already an unreleased
-version in flight), and open an editor where you can add a new changelog entry.
-(Our release process will ensure that the version number and maintainer name is
-corrected for the release.)
-
-If your change affects both the debian packaging *and* files outside the debian
-directory, you will need both a regular newsfragment *and* an entry in the
-debian changelog. (Though typically such changes should be submitted as two
-separate pull requests.)
-
-## Documentation
-
-There is a growing amount of documentation located in the [docs](docs)
-directory. This documentation is intended primarily for sysadmins running their
-own Synapse instance, as well as developers interacting externally with
-Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
-Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
-regarding Synapse's Admin API, which is used mostly by sysadmins and external
-service developers.
-
-New files added to both folders should be written in [Github-Flavoured
-Markdown](https://guides.github.com/features/mastering-markdown/), and attempts
-should be made to migrate existing documents to markdown where possible.
-
-Some documentation also exists in [Synapse's Github
-Wiki](https://github.com/matrix-org/synapse/wiki), although this is primarily
-contributed to by community authors.
-
-## Sign off
-
-In order to have a concrete record that your contribution is intentional
-and you agree to license it under the same terms as the project's license, we've adopted the
-same lightweight approach that the Linux Kernel
-[submitting patches process](
-https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin>),
-[Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
-projects use: the DCO (Developer Certificate of Origin:
-http://developercertificate.org/). This is a simple declaration that you wrote
-the contribution or otherwise have the right to contribute it to Matrix:
-
-```
-Developer Certificate of Origin
-Version 1.1
-
-Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
-660 York Street, Suite 102,
-San Francisco, CA 94110 USA
-
-Everyone is permitted to copy and distribute verbatim copies of this
-license document, but changing it is not allowed.
-
-Developer's Certificate of Origin 1.1
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the open source license
-    indicated in the file; or
-
-(b) The contribution is based upon previous work that, to the best
-    of my knowledge, is covered under an appropriate open source
-    license and I have the right under that license to submit that
-    work with modifications, whether created in whole or in part
-    by me, under the same open source license (unless I am
-    permitted to submit under a different license), as indicated
-    in the file; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a), (b) or (c) and I have not modified
-    it.
-
-(d) I understand and agree that this project and the contribution
-    are public and that a record of the contribution (including all
-    personal information I submit with it, including my sign-off) is
-    maintained indefinitely and may be redistributed consistent with
-    this project or the open source license(s) involved.
-```
-
-If you agree to this for your contribution, then all that's needed is to
-include the line in your commit or pull request comment:
-
-```
-Signed-off-by: Your Name <your@email.example.org>
-```
-
-We accept contributions under a legally identifiable name, such as
-your name on government documentation or common-law names (names
-claimed by legitimate usage or repute). Unfortunately, we cannot
-accept anonymous contributions at this time.
-
-Git allows you to add this signoff automatically when using the `-s`
-flag to `git commit`, which uses the name and email set in your
-`user.name` and `user.email` git configs.
-
-## Continuous integration and testing
-
-[Buildkite](https://buildkite.com/matrix-dot-org/synapse) will automatically
-run a series of checks and tests against any PR which is opened against the
-project; if your change breaks the build, this will be shown in GitHub, with
-links to the build results. If your build fails, please try to fix the errors
-and update your branch.
-
-To run unit tests in a local development environment, you can use:
-
-- ``tox -e py35`` (requires tox to be installed by ``pip install tox``)
-  for SQLite-backed Synapse on Python 3.5.
-- ``tox -e py36`` for SQLite-backed Synapse on Python 3.6.
-- ``tox -e py36-postgres`` for PostgreSQL-backed Synapse on Python 3.6
-  (requires a running local PostgreSQL with access to create databases).
-- ``./test_postgresql.sh`` for PostgreSQL-backed Synapse on Python 3.5
-  (requires Docker). Entirely self-contained, recommended if you don't want to
-  set up PostgreSQL yourself.
-
-Docker images are available for running the integration tests (SyTest) locally,
-see the [documentation in the SyTest repo](
-https://github.com/matrix-org/sytest/blob/develop/docker/README.md) for more
-information.
-
-## Updating your pull request
-
-If you decide to make changes to your pull request - perhaps to address issues
-raised in a review, or to fix problems highlighted by [continuous
-integration](#continuous-integration-and-testing) - just add new commits to your
-branch, and push to GitHub. The pull request will automatically be updated.
-
-Please **avoid** rebasing your branch, especially once the PR has been
-reviewed: doing so makes it very difficult for a reviewer to see what has
-changed since a previous review.
-
-## Notes for maintainers on merging PRs etc
-
-There are some notes for those with commit access to the project on how we
-manage git [here](docs/dev/git.md).
-
-## Conclusion
-
-That's it! Matrix is a very open and collaborative project as you might expect
-given our obsession with open communication. If we're going to successfully
-matrix together all the fragmented communication technologies out there we are
-reliant on contributions and collaboration from the community to do so. So
-please get involved - and we hope you have as much fun hacking on Matrix as we
-do!

-## Choosing your server name
-
-It is important to choose the name for your server before you install Synapse,
-because it cannot be changed later.
-
-The server name determines the "domain" part of user-ids for users on your
-server: these will all be of the format `@user:my.domain.name`. It also
-determines how other matrix servers will reach yours for federation.
-
-For a test configuration, set this to the hostname of your server. For a more
-production-ready setup, you will probably want to specify your domain
-(`example.com`) rather than a matrix-specific hostname here (in the same way
-that your email address is probably `user@example.com` rather than
-`user@email.example.com`) - but doing so may require more advanced setup: see
-[Setting up Federation](docs/federate.md).
-
-## Installing Synapse
-
-### Installing from source
-
-(Prebuilt packages are available for some platforms - see [Prebuilt packages](#prebuilt-packages).)
-
-System requirements:
-
-- POSIX-compliant system (tested on Linux & OS X)
-- Python 3.5.2 or later, up to Python 3.9.
-- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
-
-Synapse is written in Python but some of the libraries it uses are written in
-C. So before we can install Synapse itself we need a working C compiler and the
-header files for Python C extensions. See [Platform-Specific
-Instructions](#platform-specific-instructions) for information on installing
-these on various platforms.
-
-To install the Synapse homeserver run:
-
-```sh
-mkdir -p ~/synapse
-virtualenv -p python3 ~/synapse/env
-source ~/synapse/env/bin/activate
-pip install --upgrade pip
-pip install --upgrade setuptools
-pip install matrix-synapse
-```
-
-This will download Synapse from [PyPI](https://pypi.org/project/matrix-synapse)
-and install it, along with the python libraries it uses, into a virtual environment
-under `~/synapse/env`.  Feel free to pick a different directory if you
-prefer.
-
-This Synapse installation can then be later upgraded by using pip again with the
-update flag:
-
-```sh
-source ~/synapse/env/bin/activate
-pip install -U matrix-synapse
-```
-
-Before you can start Synapse, you will need to generate a configuration
-file. To do this, run (in your virtualenv, as before):
-
-```sh
-cd ~/synapse
-python -m synapse.app.homeserver \
-    --server-name my.domain.name \
-    --config-path homeserver.yaml \
-    --generate-config \
-    --report-stats=[yes|no]
-```
-
-... substituting an appropriate value for `--server-name`.
-
-This command will generate you a config file that you can then customise, but it will
-also generate a set of keys for you. These keys will allow your homeserver to
-identify itself to other homeserver, so don't lose or delete them. It would be
-wise to back them up somewhere safe. (If, for whatever reason, you do need to
-change your homeserver's keys, you may find that other homeserver have the
-old key cached. If you update the signing key, you should change the name of the
-key in the `<server name>.signing.key` file (the second word) to something
-different. See the [spec](https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys) for more information on key management).
-
-To actually run your new homeserver, pick a working directory for Synapse to
-run (e.g. `~/synapse`), and:
-
-```sh
-cd ~/synapse
-source env/bin/activate
-synctl start
-```
-
-#### Platform-Specific Instructions
-
-##### Debian/Ubuntu/Raspbian
-
-Installing prerequisites on Ubuntu or Debian:
-
-```sh
-sudo apt install build-essential python3-dev libffi-dev \
-                     python3-pip python3-setuptools sqlite3 \
-                     libssl-dev virtualenv libjpeg-dev libxslt1-dev
-```
-
-##### ArchLinux
-
-Installing prerequisites on ArchLinux:
-
-```sh
-sudo pacman -S base-devel python python-pip \
-               python-setuptools python-virtualenv sqlite3
-```
-
-##### CentOS/Fedora
-
-Installing prerequisites on CentOS 8 or Fedora>26:
-
-```sh
-sudo dnf install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
-                 libwebp-devel tk-devel redhat-rpm-config \
-                 python3-virtualenv libffi-devel openssl-devel
-sudo dnf groupinstall "Development Tools"
-```
-
-Installing prerequisites on CentOS 7 or Fedora<=25:
-
-```sh
-sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
-                 lcms2-devel libwebp-devel tcl-devel tk-devel redhat-rpm-config \
-                 python3-virtualenv libffi-devel openssl-devel
-sudo yum groupinstall "Development Tools"
-```
-
-Note that Synapse does not support versions of SQLite before 3.11, and CentOS 7
-uses SQLite 3.7. You may be able to work around this by installing a more
-recent SQLite version, but it is recommended that you instead use a Postgres
-database: see [docs/postgres.md](docs/postgres.md).
-
-##### macOS
-
-Installing prerequisites on macOS:
-
-```sh
-xcode-select --install
-sudo easy_install pip
-sudo pip install virtualenv
-brew install pkg-config libffi
-```
-
-On macOS Catalina (10.15) you may need to explicitly install OpenSSL
-via brew and inform `pip` about it so that `psycopg2` builds:
-
-```sh
-brew install openssl@1.1
-export LDFLAGS="-L/usr/local/opt/openssl/lib"
-export CPPFLAGS="-I/usr/local/opt/openssl/include"
-```
-
-##### OpenSUSE
-
-Installing prerequisites on openSUSE:
-
-```sh
-sudo zypper in -t pattern devel_basis
-sudo zypper in python-pip python-setuptools sqlite3 python-virtualenv \
-               python-devel libffi-devel libopenssl-devel libjpeg62-devel
-```
-
-##### OpenBSD
-
-A port of Synapse is available under `net/synapse`. The filesystem
-underlying the homeserver directory (defaults to `/var/synapse`) has to be
-mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
-and mounting it to `/var/synapse` should be taken into consideration.
-
-To be able to build Synapse's dependency on python the `WRKOBJDIR`
-(cf. `bsd.port.mk(5)`) for building python, too, needs to be on a filesystem
-mounted with `wxallowed` (cf. `mount(8)`).
-
-Creating a `WRKOBJDIR` for building python under `/usr/local` (which on a
-default OpenBSD installation is mounted with `wxallowed`):
-
-```sh
-doas mkdir /usr/local/pobj_wxallowed
-```
-
-Assuming `PORTS_PRIVSEP=Yes` (cf. `bsd.port.mk(5)`) and `SUDO=doas` are
-configured in `/etc/mk.conf`:
-
-```sh
-doas chown _pbuild:_pbuild /usr/local/pobj_wxallowed
-```
-
-Setting the `WRKOBJDIR` for building python:
-
-```sh
-echo WRKOBJDIR_lang/python/3.7=/usr/local/pobj_wxallowed  \\nWRKOBJDIR_lang/python/2.7=/usr/local/pobj_wxallowed >> /etc/mk.conf
-```
-
-Building Synapse:
-
-```sh
-cd /usr/ports/net/synapse
-make install
-```
-
-##### Windows
-
-If you wish to run or develop Synapse on Windows, the Windows Subsystem For
-Linux provides a Linux environment on Windows 10 which is capable of using the
-Debian, Fedora, or source installation methods. More information about WSL can
-be found at <https://docs.microsoft.com/en-us/windows/wsl/install-win10> for
-Windows 10 and <https://docs.microsoft.com/en-us/windows/wsl/install-on-server>
-for Windows Server.
-
-### Prebuilt packages
-
-As an alternative to installing from source, prebuilt packages are available
-for a number of platforms.
-
-#### Docker images and Ansible playbooks
-
-There is an official synapse image available at
-<https://hub.docker.com/r/matrixdotorg/synapse> which can be used with
-the docker-compose file available at [contrib/docker](contrib/docker). Further
-information on this including configuration options is available in the README
-on hub.docker.com.
-
-Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
-Dockerfile to automate a synapse server in a single Docker image, at
-<https://hub.docker.com/r/avhost/docker-matrix/tags/>
-
-Slavi Pantaleev has created an Ansible playbook,
-which installs the offical Docker image of Matrix Synapse
-along with many other Matrix-related services (Postgres database, Element, coturn,
-ma1sd, SSL support, etc.).
-For more details, see
-<https://github.com/spantaleev/matrix-docker-ansible-deploy>
-
-#### Debian/Ubuntu
-
-##### Matrix.org packages
-
-Matrix.org provides Debian/Ubuntu packages of the latest stable version of
-Synapse via <https://packages.matrix.org/debian/>. They are available for Debian
-9 (Stretch), Ubuntu 16.04 (Xenial), and later. To use them:
-
-```sh
-sudo apt install -y lsb-release wget apt-transport-https
-sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
-echo "deb [signed-by=/usr/share/keyrings/matrix-org-archive-keyring.gpg] https://packages.matrix.org/debian/ $(lsb_release -cs) main" |
-    sudo tee /etc/apt/sources.list.d/matrix-org.list
-sudo apt update
-sudo apt install matrix-synapse-py3
-```
-
-**Note**: if you followed a previous version of these instructions which
-recommended using `apt-key add` to add an old key from
-`https://matrix.org/packages/debian/`, you should note that this key has been
-revoked. You should remove the old key with `sudo apt-key remove
-C35EB17E1EAE708E6603A9B3AD0592FE47F0DF61`, and follow the above instructions to
-update your configuration.
-
-The fingerprint of the repository signing key (as shown by `gpg
-/usr/share/keyrings/matrix-org-archive-keyring.gpg`) is
-`AAF9AE843A7584B5A3E4CD2BCF45A512DE2DA058`.
-
-##### Downstream Debian packages
-
-We do not recommend using the packages from the default Debian `buster`
-repository at this time, as they are old and suffer from known security
-vulnerabilities. You can install the latest version of Synapse from
-[our repository](#matrixorg-packages) or from `buster-backports`. Please
-see the [Debian documentation](https://backports.debian.org/Instructions/)
-for information on how to use backports.
-
-If you are using Debian `sid` or testing, Synapse is available in the default
-repositories and it should be possible to install it simply with:
-
-```sh
-sudo apt install matrix-synapse
-```
-
-##### Downstream Ubuntu packages
-
-We do not recommend using the packages in the default Ubuntu repository
-at this time, as they are old and suffer from known security vulnerabilities.
-The latest version of Synapse can be installed from [our repository](#matrixorg-packages).
-
-#### Fedora
-
-Synapse is in the Fedora repositories as `matrix-synapse`:
-
-```sh
-sudo dnf install matrix-synapse
-```
-
-Oleg Girko provides Fedora RPMs at
-<https://obs.infoserver.lv/project/monitor/matrix-synapse>
-
-#### OpenSUSE
-
-Synapse is in the OpenSUSE repositories as `matrix-synapse`:
-
-```sh
-sudo zypper install matrix-synapse
-```
-
-#### SUSE Linux Enterprise Server
-
-Unofficial package are built for SLES 15 in the openSUSE:Backports:SLE-15 repository at
-<https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/>
-
-#### ArchLinux
-
-The quickest way to get up and running with ArchLinux is probably with the community package
-<https://www.archlinux.org/packages/community/any/matrix-synapse/>, which should pull in most of
-the necessary dependencies.
-
-pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 ):
-
-```sh
-sudo pip install --upgrade pip
-```
-
-If you encounter an error with lib bcrypt causing an Wrong ELF Class:
-ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
-compile it under the right architecture. (This should not be needed if
-installing under virtualenv):
-
-```sh
-sudo pip uninstall py-bcrypt
-sudo pip install py-bcrypt
-```
-
-#### Void Linux
-
-Synapse can be found in the void repositories as 'synapse':
-
-```sh
-xbps-install -Su
-xbps-install -S synapse
-```
-
-#### FreeBSD
-
-Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
-
-- Ports: `cd /usr/ports/net-im/py-matrix-synapse && make install clean`
-- Packages: `pkg install py37-matrix-synapse`
-
-#### OpenBSD
-
-As of OpenBSD 6.7 Synapse is available as a pre-compiled binary. The filesystem
-underlying the homeserver directory (defaults to `/var/synapse`) has to be
-mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
-and mounting it to `/var/synapse` should be taken into consideration.
-
-Installing Synapse:
-
-```sh
-doas pkg_add synapse
-```
-
-#### NixOS
-
-Robin Lambertz has packaged Synapse for NixOS at:
-<https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix>
-
-## Setting up Synapse
-
-Once you have installed synapse as above, you will need to configure it.
-
-### Using PostgreSQL
-
-By default Synapse uses [SQLite](https://sqlite.org/) and in doing so trades performance for convenience.
-SQLite is only recommended in Synapse for testing purposes or for servers with
-very light workloads.
-
-Almost all installations should opt to use [PostgreSQL](https://www.postgresql.org). Advantages include:
-
-- significant performance improvements due to the superior threading and
-  caching model, smarter query optimiser
-- allowing the DB to be run on separate hardware
-
-For information on how to install and use PostgreSQL in Synapse, please see
-[docs/postgres.md](docs/postgres.md)
-
-### TLS certificates
-
-The default configuration exposes a single HTTP port on the local
-interface: `http://localhost:8008`. It is suitable for local testing,
-but for any practical use, you will need Synapse's APIs to be served
-over HTTPS.
-
-The recommended way to do so is to set up a reverse proxy on port
-`8448`. You can find documentation on doing so in
-[docs/reverse_proxy.md](docs/reverse_proxy.md).
-
-Alternatively, you can configure Synapse to expose an HTTPS port. To do
-so, you will need to edit `homeserver.yaml`, as follows:
-
-- First, under the `listeners` section, uncomment the configuration for the
-  TLS-enabled listener. (Remove the hash sign (`#`) at the start of
-  each line). The relevant lines are like this:
-
-```yaml
-  - port: 8448
-    type: http
-    tls: true
-    resources:
-      - names: [client, federation]
-  ```
-
-- You will also need to uncomment the `tls_certificate_path` and
-  `tls_private_key_path` lines under the `TLS` section. You will need to manage
-  provisioning of these certificates yourself — Synapse had built-in ACME
-  support, but the ACMEv1 protocol Synapse implements is deprecated, not
-  allowed by LetsEncrypt for new sites, and will break for existing sites in
-  late 2020. See [ACME.md](docs/ACME.md).
-
-  If you are using your own certificate, be sure to use a `.pem` file that
-  includes the full certificate chain including any intermediate certificates
-  (for instance, if using certbot, use `fullchain.pem` as your certificate, not
-  `cert.pem`).
-
-For a more detailed guide to configuring your server for federation, see
-[federate.md](docs/federate.md).
-
-### Client Well-Known URI
-
-Setting up the client Well-Known URI is optional but if you set it up, it will
-allow users to enter their full username (e.g. `@user:<server_name>`) into clients
-which support well-known lookup to automatically configure the homeserver and
-identity server URLs. This is useful so that users don't have to memorize or think
-about the actual homeserver URL you are using.
-
-The URL `https://<server_name>/.well-known/matrix/client` should return JSON in
-the following format.
-
-```json
-{
-  "m.homeserver": {
-    "base_url": "https://<matrix.example.com>"
-  }
-}
-```
-
-It can optionally contain identity server information as well.
-
-```json
-{
-  "m.homeserver": {
-    "base_url": "https://<matrix.example.com>"
-  },
-  "m.identity_server": {
-    "base_url": "https://<identity.example.com>"
-  }
-}
-```
-
-To work in browser based clients, the file must be served with the appropriate
-Cross-Origin Resource Sharing (CORS) headers. A recommended value would be
-`Access-Control-Allow-Origin: *` which would allow all browser based clients to
-view it.
-
-In nginx this would be something like:
-
-```nginx
-location /.well-known/matrix/client {
-    return 200 '{"m.homeserver": {"base_url": "https://<matrix.example.com>"}}';
-    default_type application/json;
-    add_header Access-Control-Allow-Origin *;
-}
-```
-
-You should also ensure the `public_baseurl` option in `homeserver.yaml` is set
-correctly. `public_baseurl` should be set to the URL that clients will use to
-connect to your server. This is the same URL you put for the `m.homeserver`
-`base_url` above.
-
-```yaml
-public_baseurl: "https://<matrix.example.com>"
-```
-
-### Email
-
-It is desirable for Synapse to have the capability to send email. This allows
-Synapse to send password reset emails, send verifications when an email address
-is added to a user's account, and send email notifications to users when they
-receive new messages.
-
-To configure an SMTP server for Synapse, modify the configuration section
-headed `email`, and be sure to have at least the `smtp_host`, `smtp_port`
-and `notif_from` fields filled out.  You may also need to set `smtp_user`,
-`smtp_pass`, and `require_transport_security`.
-
-If email is not configured, password reset, registration and notifications via
-email will be disabled.
-
-### Registering a user
-
-The easiest way to create a new user is to do so from a client like [Element](https://element.io/).
-
-Alternatively you can do so from the command line if you have installed via pip.
-
-This can be done as follows:
-
-```sh
-$ source ~/synapse/env/bin/activate
-$ synctl start # if not already running
-$ register_new_matrix_user -c homeserver.yaml http://localhost:8008
-New user localpart: erikj
-Password:
-Confirm password:
-Make admin [no]:
-Success!
-```
-
-This process uses a setting `registration_shared_secret` in
-`homeserver.yaml`, which is shared between Synapse itself and the
-`register_new_matrix_user` script. It doesn't matter what it is (a random
-value is generated by `--generate-config`), but it should be kept secret, as
-anyone with knowledge of it can register users, including admin accounts,
-on your server even if `enable_registration` is `false`.
-
-### Setting up a TURN server
-
-For reliable VoIP calls to be routed via this homeserver, you MUST configure
-a TURN server. See [docs/turn-howto.md](docs/turn-howto.md) for details.
-
-### URL previews
-
-Synapse includes support for previewing URLs, which is disabled by default.  To
-turn it on you must enable the `url_preview_enabled: True` config parameter
-and explicitly specify the IP ranges that Synapse is not allowed to spider for
-previewing in the `url_preview_ip_range_blacklist` configuration parameter.
-This is critical from a security perspective to stop arbitrary Matrix users
-spidering 'internal' URLs on your network. At the very least we recommend that
-your loopback and RFC1918 IP addresses are blacklisted.
-
-This also requires the optional `lxml` python dependency to be  installed. This
-in turn requires the `libxml2` library to be available - on  Debian/Ubuntu this
-means `apt-get install libxml2-dev`, or equivalent for your OS.
-
-### Troubleshooting Installation
-
-`pip` seems to leak *lots* of memory during installation. For instance, a Linux
-host with 512MB of RAM may run out of memory whilst installing Twisted. If this
-happens, you will have to individually install the dependencies which are
-failing, e.g.:
-
-```sh
-pip install twisted
-```
-
-If you have any other problems, feel free to ask in
-[#synapse:matrix.org](https://matrix.to/#/#synapse:matrix.org).

-https://developer.github.com/changes/2014-04-25-user-content-security for more details.
+Whilst we make a reasonable effort to mitigate against XSS attacks (for

+https://developer.github.com/changes/2014-04-25-user-content-security for more
+information.
+
+.. _CSP: https://github.com/matrix-org/synapse/pull/1021
+
+Ideally, the homeserver should not simply be on a different subdomain, but on
+a completely different `registered domain`_ (also known as top-level site or
+eTLD+1). This is because `some attacks`_ are still possible as long as the two
+applications share the same registered domain.
+
+.. _registered domain: https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-03#section-2.3
+
+.. _some attacks: https://en.wikipedia.org/wiki/Session_fixation#Attacks_using_cross-subdomain_cookie
+
+To illustrate this with an example, if your Element Web or other sensitive web
+application is hosted on ``A.example1.com``, you should ideally host Synapse on
+``example2.com``. Some amount of protection is offered by hosting on
+``B.example1.com`` instead, so this is also acceptable in some scenarios.
+However, you should *not* host your Synapse on ``A.example1.com``.
+
+Note that all of the above refers exclusively to the domain used in Synapse's
+``public_baseurl`` setting. In particular, it has no bearing on the domain
+mentioned in MXIDs hosted on that server.
+
+Following this advice ensures that even if an XSS is found in Synapse, the
+impact to other applications will be minimal.

 \fBSYNAPSE_CACHE_FACTOR\fR
-Synapse\'s architecture is quite RAM hungry currently \- a lot of recent room data and metadata is deliberately cached in RAM in order to speed up common requests\. This will be improved in future, but for now the easiest way to either reduce the RAM usage (at the risk of slowing things down) is to set the SYNAPSE_CACHE_FACTOR environment variable\. Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1\.0 will max out at around 3\-4GB of resident memory \- this is what we currently run the matrix\.org on\. The default setting is currently 0\.1, which is probably around a ~700MB footprint\. You can dial it down further to 0\.02 if desired, which targets roughly ~512MB\. Conversely you can dial it up if you need performance for lots of users and have a box with a lot of RAM\.

+Synapse\'s architecture is quite RAM hungry currently \- we deliberately cache a lot of recent room data and metadata in RAM in order to speed up common requests\. We\'ll improve this in the future, but for now the easiest way to either reduce the RAM usage (at the risk of slowing things down) is to set the almost\-undocumented \fBSYNAPSE_CACHE_FACTOR\fR environment variable\. The default is 0\.5, which can be decreased to reduce RAM usage in memory constrained enviroments, or increased if performance starts to degrade\.
+.IP
+However, degraded performance due to a low cache factor, common on machines with slow disks, often leads to explosions in memory use due backlogged requests\. In this case, reducing the cache factor will make things worse\. Instead, try increasing it drastically\. 2\.0 is a good starting value\.

+# Running tests against a dockerised Synapse
+
+It's possible to run integration tests against Synapse
+using [Complement](https://github.com/matrix-org/complement). Complement is a Matrix Spec
+compliance test suite for homeservers, and supports any homeserver docker image configured
+to listen on ports 8008/8448. This document contains instructions for building Synapse
+docker images that can be run inside Complement for testing purposes.
+
+Note that running Synapse's unit tests from within the docker image is not supported.
+
+## Testing with SQLite and single-process Synapse
+
+> Note that `scripts-dev/complement.sh` is a script that will automatically build 
+> and run an SQLite-based, single-process of Synapse against Complement.
+
+The instructions below will set up Complement testing for a single-process, 
+SQLite-based Synapse deployment.
+
+Start by building the base Synapse docker image. If you wish to run tests with the latest
+release of Synapse, instead of your current checkout, you can skip this step. From the
+root of the repository:
+
+```sh
+docker build -t matrixdotorg/synapse -f docker/Dockerfile .
+```
+
+This will build an image with the tag `matrixdotorg/synapse`.
+
+Next, build the Synapse image for Complement. You will need a local checkout 
+of Complement. Change to the root of your Complement checkout and run:
+
+```sh
+docker build -t complement-synapse -f "dockerfiles/Synapse.Dockerfile" dockerfiles
+```
+
+This will build an image with the tag `complement-synapse`, which can be handed to 
+Complement for testing via the `COMPLEMENT_BASE_IMAGE` environment variable. Refer to 
+[Complement's documentation](https://github.com/matrix-org/complement/#running) for 
+how to run the tests, as well as the various available command line flags.
+
+## Testing with PostgreSQL and single or multi-process Synapse
+
+The above docker image only supports running Synapse with SQLite and in a 
+single-process topology. The following instructions are used to build a Synapse image for 
+Complement that supports either single or multi-process topology with a PostgreSQL 
+database backend.
+
+As with the single-process image, build the base Synapse docker image. If you wish to run
+tests with the latest release of Synapse, instead of your current checkout, you can skip
+this step. From the root of the repository:
+
+```sh
+docker build -t matrixdotorg/synapse -f docker/Dockerfile .
+```
+
+This will build an image with the tag `matrixdotorg/synapse`.
+
+Next, we build a new image with worker support based on `matrixdotorg/synapse:latest`. 
+Again, from the root of the repository:
+
+```sh
+docker build -t matrixdotorg/synapse-workers -f docker/Dockerfile-workers .
+```
+
+This will build an image with the tag` matrixdotorg/synapse-workers`.
+
+It's worth noting at this point that this image is fully functional, and 
+can be used for testing against locally. See instructions for using the container 
+under
+[Running the Dockerfile-worker image standalone](#running-the-dockerfile-worker-image-standalone)
+below.
+
+Finally, build the Synapse image for Complement, which is based on
+`matrixdotorg/synapse-workers`. You will need a local checkout of Complement. Change to
+the root of your Complement checkout and run:
+
+```sh
+docker build -t matrixdotorg/complement-synapse-workers -f dockerfiles/SynapseWorkers.Dockerfile dockerfiles
+```
+
+This will build an image with the tag `complement-synapse`, which can be handed to
+Complement for testing via the `COMPLEMENT_BASE_IMAGE` environment variable. Refer to
+[Complement's documentation](https://github.com/matrix-org/complement/#running) for
+how to run the tests, as well as the various available command line flags.
+
+## Running the Dockerfile-worker image standalone
+
+For manual testing of a multi-process Synapse instance in Docker,
+[Dockerfile-workers](Dockerfile-workers) is a Dockerfile that will produce an image
+bundling all necessary components together for a workerised homeserver instance.
+
+This includes any desired Synapse worker processes, a nginx to route traffic accordingly,
+a redis for worker communication and a supervisord instance to start up and monitor all
+processes. You will need to provide your own postgres container to connect to, and TLS 
+is not handled by the container.
+
+Once you've built the image using the above instructions, you can run it. Be sure 
+you've set up a volume according to the [usual Synapse docker instructions](README.md).
+Then run something along the lines of:
+
+```
+docker run -d --name synapse \
+    --mount type=volume,src=synapse-data,dst=/data \
+    -p 8008:8008 \
+    -e SYNAPSE_SERVER_NAME=my.matrix.host \
+    -e SYNAPSE_REPORT_STATS=no \
+    -e POSTGRES_HOST=postgres \
+    -e POSTGRES_USER=postgres \
+    -e POSTGRES_PASSWORD=somesecret \
+    -e SYNAPSE_WORKER_TYPES=synchrotron,media_repository,user_dir \
+    -e SYNAPSE_WORKERS_WRITE_LOGS_TO_DISK=1 \
+    matrixdotorg/synapse-workers
+```
+
+...substituting `POSTGRES*` variables for those that match a postgres host you have 
+available (usually a running postgres docker container).
+
+The `SYNAPSE_WORKER_TYPES` environment variable is a comma-separated list of workers to
+use when running the container. All possible worker names are defined by the keys of the
+`WORKERS_CONFIG` variable in [this script](configure_workers_and_start.py), which the
+Dockerfile makes use of to generate appropriate worker, nginx and supervisord config
+files.
+
+Sharding is supported for a subset of workers, in line with the
+[worker documentation](../docs/workers.md). To run multiple instances of a given worker
+type, simply specify the type multiple times in `SYNAPSE_WORKER_TYPES`
+(e.g `SYNAPSE_WORKER_TYPES=event_creator,event_creator...`).
+
+Otherwise, `SYNAPSE_WORKER_TYPES` can either be left empty or unset to spawn no workers
+(leaving only the main process). The container is configured to use redis-based worker
+mode.
+
+Logs for workers and the main process are logged to stdout and can be viewed with 
+standard `docker logs` tooling. Worker logs contain their worker name 
+after the timestamp.
+
+Setting `SYNAPSE_WORKERS_WRITE_LOGS_TO_DISK=1` will cause worker logs to be written to
+`<data_dir>/logs/<worker_name>.log`. Logs are kept for 1 week and rotate every day at 00:
+00, according to the container's clock. Logging for the main process must still be 
+configured by modifying the homeserver's log config in your Synapse data volume.

-# ACME
-
-From version 1.0 (June 2019) onwards, Synapse requires valid TLS
-certificates for communication between servers (by default on port
-`8448`) in addition to those that are client-facing (port `443`). To
-help homeserver admins fulfil this new requirement, Synapse v0.99.0
-introduced support for automatically provisioning certificates through 
-[Let's Encrypt](https://letsencrypt.org/) using the ACME protocol.
-
-## Deprecation of ACME v1
-
-In [March 2019](https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430),
-Let's Encrypt announced that they were deprecating version 1 of the ACME
-protocol, with the plan to disable the use of it for new accounts in
-November 2019, for new domains in June 2020, and for existing accounts and
-domains in June 2021.
-
-Synapse doesn't currently support version 2 of the ACME protocol, which
-means that:
-
-* for existing installs, Synapse's built-in ACME support will continue
-  to work until June 2021.
-* for new installs, this feature will not work at all.
-
-Either way, it is recommended to move from Synapse's ACME support
-feature to an external automated tool such as [certbot](https://github.com/certbot/certbot)
-(or browse [this list](https://letsencrypt.org/fr/docs/client-options/)
-for an alternative ACME client).
-
-It's also recommended to use a reverse proxy for the server-facing
-communications (more documentation about this can be found
-[here](/docs/reverse_proxy.md)) as well as the client-facing ones and
-have it serve the certificates.
-
-In case you can't do that and need Synapse to serve them itself, make
-sure to set the `tls_certificate_path` configuration setting to the path
-of the certificate (make sure to use the certificate containing the full
-certification chain, e.g. `fullchain.pem` if using certbot) and
-`tls_private_key_path` to the path of the matching private key. Note
-that in this case you will need to restart Synapse after each
-certificate renewal so that Synapse stops using the old certificate.
-
-If you still want to use Synapse's built-in ACME support, the rest of
-this document explains how to set it up. 
-
-## Initial setup 
-
-In the case that your `server_name` config variable is the same as
-the hostname that the client connects to, then the same certificate can be
-used between client and federation ports without issue.
-
-If your configuration file does not already have an `acme` section, you can
-generate an example config by running the `generate_config` executable. For
-example:

-
-You will need to provide Let's Encrypt (or another ACME provider) access to
-your Synapse ACME challenge responder on port 80, at the domain of your
-homeserver. This requires you to either change the port of the ACME listener
-provided by Synapse to a high port and reverse proxy to it, or use a tool
-like `authbind` to allow Synapse to listen on port 80 without root access.
-(Do not run Synapse with root permissions!) Detailed instructions are
-available under "ACME setup" below.
-
-If you already have certificates, you will need to back up or delete them
-(files `example.com.tls.crt` and `example.com.tls.key` in Synapse's root
-directory), Synapse's ACME implementation will not overwrite them.
-
-## ACME setup
-
-The main steps for enabling ACME support in short summary are:
-
-1. Allow Synapse to listen for incoming ACME challenges.
-1. Enable ACME support in `homeserver.yaml`.
-1. Move your old certificates (files `example.com.tls.crt` and `example.com.tls.key` out of the way if they currently exist at the paths specified in `homeserver.yaml`.
-1. Restart Synapse.
-
-Detailed instructions for each step are provided below.
-
-### Listening on port 80
-
-In order for Synapse to complete the ACME challenge to provision a
-certificate, it needs access to port 80. Typically listening on port 80 is
-only granted to applications running as root. There are thus two solutions to
-this problem.
-
-#### Using a reverse proxy
-
-A reverse proxy such as Apache or nginx allows a single process (the web
-server) to listen on port 80 and proxy traffic to the appropriate program
-running on your server. It is the recommended method for setting up ACME as
-it allows you to use your existing webserver while also allowing Synapse to
-provision certificates as needed.
-
-For nginx users, add the following line to your existing `server` block:
-
-```
-location /.well-known/acme-challenge {
-    proxy_pass http://localhost:8009;
-}
-```
-
-For Apache, add the following to your existing webserver config:
-
-```
-ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge
-```
-
-Make sure to restart/reload your webserver after making changes.
-
-Now make the relevant changes in `homeserver.yaml` to enable ACME support:
-
-```
-acme:
-    enabled: true
-    port: 8009
-```
-
-#### Authbind
-
-`authbind` allows a program which does not run as root to bind to
-low-numbered ports in a controlled way. The setup is simpler, but requires a
-webserver not to already be running on port 80. **This includes every time
-Synapse renews a certificate**, which may be cumbersome if you usually run a
-web server on port 80. Nevertheless, if you're sure port 80 is not being used
-for any other purpose then all that is necessary is the following:
-
-Install `authbind`. For example, on Debian/Ubuntu:
-
-```
-sudo apt-get install authbind
-```
-
-Allow `authbind` to bind port 80:
-
-```
-sudo touch /etc/authbind/byport/80
-sudo chmod 777 /etc/authbind/byport/80
-```
-
-When Synapse is started, use the following syntax:
-
-```
-authbind --deep <synapse start command>
-```
-
-Make the relevant changes in `homeserver.yaml` to enable ACME support:
-
-```
-acme:
-    enabled: true
-```
-
-### (Re)starting synapse
-
-Ensure that the certificate paths specified in `homeserver.yaml` (`tls_certificate_path` and `tls_private_key_path`) do not currently point to any files. Synapse will not provision certificates if files exist, as it does not want to overwrite existing certificates.
-
-Finally, start/restart Synapse.

 # Synapse Documentation
 
-This directory contains documentation specific to the `synapse` homeserver.
+**The documentation is currently hosted [here](https://matrix-org.github.io/synapse).**
+Please update any links to point to the new website instead.
 
-All matrix-generic documentation now lives in its own project, located at [matrix-org/matrix-doc](https://github.com/matrix-org/matrix-doc)
+## About
 
-(Note:  some items here may be moved to [matrix-org/matrix-doc](https://github.com/matrix-org/matrix-doc) at some point in the future.)
+This directory currently holds a series of markdown files documenting how to install, use
+and develop Synapse, the reference Matrix homeserver. The documentation is readable directly
+from this repository, but it is recommended to instead browse through the
+[website](https://matrix-org.github.io/synapse) for easier discoverability.
+
+## Adding to the documentation
+
+Most of the documentation currently exists as top-level files, as when organising them into
+a structured website, these files were kept in place so that existing links would not break.
+The rest of the documentation is stored in folders, such as `setup`, `usage`, and `development`
+etc. **All new documentation files should be placed in structured folders.** For example:
+
+To create a new user-facing documentation page about a new Single Sign-On protocol named
+"MyCoolProtocol", one should create a new file with a relevant name, such as "my_cool_protocol.md".
+This file might fit into the documentation structure at:
+
+- Usage
+  - Configuration
+    - User Authentication
+      - Single Sign-On
+        - **My Cool Protocol**
+
+Given that, one would place the new file under
+`usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md`.
+
+Note that the structure of the documentation (and thus the left sidebar on the website) is determined
+by the list in [SUMMARY.md](SUMMARY.md). The final thing to do when adding a new page is to add a new
+line linking to the new documentation file:
+
+```markdown
+- [My Cool Protocol](usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md)
+```
+
+## Building the documentation
+
+The documentation is built with [mdbook](https://rust-lang.github.io/mdBook/), and the outline of the
+documentation is determined by the structure of [SUMMARY.md](SUMMARY.md).
+
+First, [get mdbook](https://github.com/rust-lang/mdBook#installation). Then, **from the root of the repository**,
+build the documentation with:
+
+```sh
+mdbook build
+```
+
+The rendered contents will be outputted to a new `book/` directory at the root of the repository. You can
+browse the book by opening `book/index.html` in a web browser.
+
+You can also have mdbook host the docs on a local webserver with hot-reload functionality via:
+
+```sh
+mdbook serve
+```
+
+The URL at which the docs can be viewed at will be logged.
+
+## Configuration and theming
+
+The look and behaviour of the website is configured by the [book.toml](../book.toml) file
+at the root of the repository. See
+[mdbook's documentation on configuration](https://rust-lang.github.io/mdBook/format/config.html)
+for available options.
+
+The site can be themed and additionally extended with extra UI and features. See
+[website_files/README.md](website_files/README.md) for details.
