+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).
+**The single biggest thing you need to know is: please base your changes on
+the develop branch - *not* master.**
 
- * Please include a [changelog entry](#changelog) with each PR.
+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.
 
- * Please [sign off](#sign-off) your contribution.
+We use [Buildkite](https://buildkite.com/matrix-dot-org/synapse) for continuous
+integration. If your change breaks the build, this will be shown in GitHub, so
+please keep an eye on the pull request for feedback.

+1. Create a new directory in `/usr/local` called `_synapse`. Also, create a
+   new user called `_synapse` and set that directory as the new user's home.
+   This is required because, by default, OpenBSD only allows binaries which need
+   write and execute permissions on the same memory space to be run from
+   `/usr/local`.
+2. `su` to the new `_synapse` user and change to their home directory.
+3. Create a new virtualenv: `virtualenv -p python2.7 ~/.synapse`
+4. Source the virtualenv configuration located at
+   `/usr/local/_synapse/.synapse/bin/activate`. This is done in `ksh` by
+   using the `.` command, rather than `bash`'s `source`.
+5. Optionally, use `pip` to install `lxml`, which Synapse needs to parse
+   webpages for their titles.
+6. Use `pip` to install this repository: `pip install matrix-synapse`
+7. Optionally, change `_synapse`'s shell to `/bin/false` to reduce the

+Using PostgreSQL
+================

+Synapse offers two database engines:

+ * `PostgreSQL <https://www.postgresql.org>`_

+By default Synapse uses SQLite in and doing so trades performance for convenience.
+SQLite is only recommended in Synapse for testing purposes or for servers with
+light workloads.
+
+Almost all installations should opt to use PostreSQL. Advantages include:

+* allowing the DB to be run on separate hardware
+* allowing basic active/backup high-availability with a "hot spare" synapse

-====================
-
-Docker `-py3` suffix will be removed in future versions
--------------------------------------------------------
-
-From 10th August 2020, we will no longer publish Docker images with the `-py3` tag suffix. The images tagged with the `-py3` suffix have been identical to the non-suffixed tags since release 0.99.0, and the suffix is obsolete.
-
-On 10th August, we will remove the `latest-py3` tag. Existing per-release tags (such as `v1.18.0-py3`) will not be removed, but no new `-py3` tags will be added.
-
-Scripts relying on the `-py3` suffix will need to be updated.
-
-Redis replication is now recommended in lieu of TCP replication

-
-When setting up worker processes, we now recommend the use of a Redis server for replication. **The old direct TCP connection method is deprecated and will be removed in a future release.**
-See `docs/workers.md <docs/workers.md>`_ for more details.
-
-Upgrading to v1.14.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take a couple of minutes in the case of a large server. Synapse
-will not respond to HTTP requests while this update is taking place.
-
-Upgrading to v1.13.0
-====================
-
-Incorrect database migration in old synapse versions
-----------------------------------------------------
-
-A bug was introduced in Synapse 1.4.0 which could cause the room directory to
-be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
-earlier, to versions between v1.4.0 and v1.12.x.
-
-This will *not* be a problem for Synapse installations which were:
- * created at v1.4.0 or later,
- * upgraded via v1.3.x, or
- * upgraded straight from v1.2.1 or earlier to v1.13.0 or later.
-
-If completeness of the room directory is a concern, installations which are
-affected can be repaired as follows:
-
-1. Run the following sql from a `psql` or `sqlite3` console:
-
-   .. code:: sql
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_rooms', '{}', 'current_state_events_membership');
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_users', '{}', 'populate_stats_process_rooms');
-
-2. Restart synapse.
-
-New Single Sign-on HTML Templates
----------------------------------
-
-New templates (``sso_auth_confirm.html``, ``sso_auth_success.html``, and
-``sso_account_deactivated.html``) were added to Synapse. If your Synapse is
-configured to use SSO and a custom  ``sso_redirect_confirm_template_dir``
-configuration then these templates will need to be copied from
-`synapse/res/templates <synapse/res/templates>`_ into that directory.
-
-Synapse SSO Plugins Method Deprecation
---------------------------------------
-
-Plugins using the ``complete_sso_login`` method of
-``synapse.module_api.ModuleApi`` should update to using the async/await
-version ``complete_sso_login_async`` which includes additional checks. The
-non-async version is considered deprecated.
-
-Rolling back to v1.12.4 after a failed upgrade
-----------------------------------------------
-
-v1.13.0 includes a lot of large changes. If something problematic occurs, you
-may want to roll-back to a previous version of Synapse. Because v1.13.0 also
-includes a new database schema version, reverting that version is also required
-alongside the generic rollback instructions mentioned above. In short, to roll
-back to v1.12.4 you need to:
-
-1. Stop the server
-2. Decrease the schema version in the database:
-
-   .. code:: sql
-
-      UPDATE schema_version SET version = 57;
-
-3. Downgrade Synapse by following the instructions for your installation method
-   in the "Rolling back to older versions" section above.
-
-
-Upgrading to v1.12.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take some time (several hours in the case of a large
-server). Synapse will not respond to HTTP requests while this update is taking
-place.
-
-This is only likely to be a problem in the case of a server which is
-participating in many rooms.
-
-0. As with all upgrades, it is recommended that you have a recent backup of
-   your database which can be used for recovery in the event of any problems.
-
-1. As an initial check to see if you will be affected, you can try running the
-   following query from the `psql` or `sqlite3` console. It is safe to run it
-   while Synapse is still running.
-
-   .. code:: sql
-
-      SELECT MAX(q.v) FROM (
-        SELECT (
-          SELECT ej.json AS v
-          FROM state_events se INNER JOIN event_json ej USING (event_id)
-          WHERE se.room_id=rooms.room_id AND se.type='m.room.create' AND se.state_key=''
-          LIMIT 1
-        ) FROM rooms WHERE rooms.room_version IS NULL
-      ) q;
-
-   This query will take about the same amount of time as the upgrade process: ie,
-   if it takes 5 minutes, then it is likely that Synapse will be unresponsive for
-   5 minutes during the upgrade.
-
-   If you consider an outage of this duration to be acceptable, no further
-   action is necessary and you can simply start Synapse 1.12.0.
-
-   If you would prefer to reduce the downtime, continue with the steps below.
-
-2. The easiest workaround for this issue is to manually
-   create a new index before upgrading. On PostgreSQL, his can be done as follows:
-
-   .. code:: sql
-
-      CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
-      ON state_events(room_id) WHERE type = 'm.room.create';
-
-   The above query may take some time, but is also safe to run while Synapse is
-   running.
-
-   We assume that no SQLite users have databases large enough to be
-   affected. If you *are* affected, you can run a similar query, omitting the
-   ``CONCURRENTLY`` keyword. Note however that this operation may in itself cause
-   Synapse to stop running for some time. Synapse admins are reminded that
-   `SQLite is not recommended for use outside a test
-   environment <https://github.com/matrix-org/synapse/blob/master/README.rst#using-postgresql>`_.
-
-3. Once the index has been created, the ``SELECT`` query in step 1 above should
-   complete quickly. It is therefore safe to upgrade to Synapse 1.12.0.
-
-4. Once Synapse 1.12.0 has successfully started and is responding to HTTP
-   requests, the temporary index can be removed:
-
-   .. code:: sql
-
-      DROP INDEX tmp_upgrade_1_12_0_index;
-
-Upgrading to v1.10.0
-====================
-
-Synapse will now log a warning on start up if used with a PostgreSQL database
-that has a non-recommended locale set.
-
-See `docs/postgres.md <docs/postgres.md>`_ for details.

-The documentation for using systemd to manage synapse workers is now part of
-the main synapse distribution. See [docs/systemd-with-workers](../../docs/systemd-with-workers).
+# Setup Synapse with Workers and Systemd
+
+This is a setup for managing synapse with systemd including support for
+managing workers. It provides a `matrix-synapse`, as well as a
+`matrix-synapse-worker@` service for any workers you require. Additionally to
+group the required services it sets up a `matrix.target`. You can use this to
+automatically start any bot- or bridge-services. More on this in
+[Bots and Bridges](#bots-and-bridges).
+
+See the folder [system](system) for any service and target files.
+
+The folder [workers](workers) contains an example configuration for the
+`federation_reader` worker. Pay special attention to the name of the
+configuration file. In order to work with the `matrix-synapse-worker@.service`
+service, it needs to have the exact same name as the worker app.
+
+This setup expects neither the homeserver nor any workers to fork. Forking is
+handled by systemd.
+
+## Setup
+
+1. Adjust your matrix configs. Make sure that the worker config files have the
+exact same name as the worker app. Compare `matrix-synapse-worker@.service` for
+why. You can find an example worker config in the [workers](workers) folder. See
+below for relevant settings in the `homeserver.yaml`.
+2. Copy the `*.service` and `*.target` files in [system](system) to
+`/etc/systemd/system`.
+3. `systemctl enable matrix-synapse.service` this adds the homeserver
+app to the `matrix.target`
+4. *Optional.* `systemctl enable
+matrix-synapse-worker@federation_reader.service` this adds the federation_reader
+app to the `matrix-synapse.service`
+5. *Optional.* Repeat step 4 for any additional workers you require.
+6. *Optional.* Add any bots or bridges by enabling them.
+7. Start all matrix related services via `systemctl start matrix.target`
+8. *Optional.* Enable autostart of all matrix related services on system boot
+via `systemctl enable matrix.target`
+
+## Usage
+
+After you have setup you can use the following commands to manage your synapse
+installation:
+
+```
+# Start matrix-synapse, all workers and any enabled bots or bridges.
+systemctl start matrix.target
+
+# Restart matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl restart matrix-synapse.service
+
+# Stop matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl stop matrix-synapse.service
+
+# Restart a specific worker (i. e. federation_reader), the homeserver is
+# unaffected by this.
+systemctl restart matrix-synapse-worker@federation_reader.service
+
+# Add a new worker (assuming all configs are setup already)
+systemctl enable matrix-synapse-worker@federation_writer.service
+systemctl restart matrix-synapse.service
+```
+
+## The Configs
+
+Make sure the `worker_app` is set in the `homeserver.yaml` and it does not fork.
+
+```
+worker_app: synapse.app.homeserver 
+daemonize: false
+```
+
+None of the workers should fork, as forking is handled by systemd. Hence make
+sure this is present in all worker config files.
+
+```
+worker_daemonize: false
+```
+
+The config files of all workers are expected to be located in
+`/etc/matrix-synapse/workers`. If you want to use a different location you have
+to edit the provided `*.service` files accordingly.  
+
+## Bots and Bridges
+
+Most bots and bridges do not care if the homeserver goes down or is restarted.
+Depending on the implementation this may crash them though. So look up the docs
+or ask the community of the specific bridge or bot you want to run to make sure
+you choose the correct setup.
+
+Whichever configuration you choose, after the setup the following will enable
+automatically starting (and potentially restarting) your bot/bridge with the
+`matrix.target`.
+
+```
+systemctl enable <yourBotOrBridgeName>.service
+```
+
+**Note** that from an inactive synapse the bots/bridges will only be started with
+synapse if you start the `matrix.target`, not if you start the
+`matrix-synapse.service`. This is on purpose. Think of `matrix-synapse.service`
+as *just* synapse, but `matrix.target` being anything matrix related, including
+synapse and any and all enabled bots and bridges.
+
+### Start with synapse but ignore synapse going down
+
+If the bridge can handle shutdowns of the homeserver you'll want to install the
+service in the `matrix.target` and optionally add a
+`After=matrix-synapse.service` dependency to have the bot/bridge start after
+synapse on starting everything.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Optional, this will only ensure that if you start everything, synapse will
+# be started before the bot/bridge will be started.
+After=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]
+WantedBy=matrix.target
+```
+
+### Stop/restart when synapse stops/restarts
+
+If the bridge can't handle shutdowns of the homeserver you'll still want to
+install the service in the `matrix.target` but also have to specify the
+`After=matrix-synapse.service` *and* `BindsTo=matrix-synapse.service`
+dependencies to have the bot/bridge stop/restart with synapse.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Mandatory
+After=matrix-synapse.service
+BindsTo=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]
+WantedBy=matrix.target
+```

 # 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

-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

-server. There are various parameters available that allow for filtering and
-sorting the returned list. This API supports pagination.
-
-## Parameters
-
-The following query parameters are available:
-
-* `from` - Offset in the returned list. Defaults to `0`.
-* `limit` - Maximum amount of rooms to return. Defaults to `100`.
-* `order_by` - The method in which to sort the returned list of rooms. Valid values are:
-  - `alphabetical` - Same as `name`. This is deprecated.
-  - `size` - Same as `joined_members`. This is deprecated.
-  - `name` - Rooms are ordered alphabetically by room name. This is the default.
-  - `canonical_alias` - Rooms are ordered alphabetically by main alias address of the room.
-  - `joined_members` - Rooms are ordered by the number of members. Largest to smallest.
-  - `joined_local_members` - Rooms are ordered by the number of local members. Largest to smallest.
-  - `version` - Rooms are ordered by room version. Largest to smallest.
-  - `creator` - Rooms are ordered alphabetically by creator of the room.
-  - `encryption` - Rooms are ordered alphabetically by the end-to-end encryption algorithm.
-  - `federatable` - Rooms are ordered by whether the room is federatable.
-  - `public` - Rooms are ordered by visibility in room list.
-  - `join_rules` - Rooms are ordered alphabetically by join rules of the room.
-  - `guest_access` - Rooms are ordered alphabetically by guest access option of the room.
-  - `history_visibility` - Rooms are ordered alphabetically by visibility of history of the room.
-  - `state_events` - Rooms are ordered by number of state events. Largest to smallest.
-* `dir` - Direction of room order. Either `f` for forwards or `b` for backwards. Setting
-          this value to `b` will reverse the above sort order. Defaults to `f`.
-* `search_term` - Filter rooms by their room name. Search term can be contained in any
-                  part of the room name. Defaults to no filtering.
-
-The following fields are possible in the JSON response body:
-
-* `rooms` - An array of objects, each containing information about a room.
-  - Room objects contain the following fields:
-    - `room_id` - The ID of the room.
-    - `name` - The name of the room.
-    - `canonical_alias` - The canonical (main) alias address of the room.
-    - `joined_members` - How many users are currently in the room.
-    - `joined_local_members` - How many local users are currently in the room.
-    - `version` - The version of the room as a string.
-    - `creator` - The `user_id` of the room creator.
-    - `encryption` - Algorithm of end-to-end encryption of messages. Is `null` if encryption is not active.
-    - `federatable` - Whether users on other servers can join this room.
-    - `public` - Whether the room is visible in room directory.
-    - `join_rules` - The type of rules used for users wishing to join this room. One of: ["public", "knock", "invite", "private"].
-    - `guest_access` - Whether guests can join the room. One of: ["can_join", "forbidden"].
-    - `history_visibility` - Who can see the room history. One of: ["invited", "joined", "shared", "world_readable"].
-    - `state_events` - Total number of state_events of a room. Complexity of the room.
-* `offset` - The current pagination offset in rooms. This parameter should be
-             used instead of `next_token` for room offset as `next_token` is
-             not intended to be parsed.
-* `total_rooms` - The total number of rooms this query can return. Using this
-                  and `offset`, you have enough information to know the current
-                  progression through the list.
-* `next_batch` - If this field is present, we know that there are potentially
-                 more rooms on the server that did not all fit into this response.
-                 We can use `next_batch` to get the "next page" of results. To do
-                 so, simply repeat your request, setting the `from` parameter to
-                 the value of `next_batch`.
-* `prev_batch` - If this field is present, it is possible to paginate backwards.
-                 Use `prev_batch` for the `from` value in the next request to
-                 get the "previous page" of results.

-# Delete Room API
-
-The Delete Room admin API allows server admins to remove rooms from server
-and block these rooms.
-It is a combination and improvement of "[Shutdown room](shutdown_room.md)"
-and "[Purge room](purge_room.md)" API.
-
-Shuts down a room. Moves all local users and room aliases automatically to a
-new room if `new_room_user_id` is set. Otherwise local users only
-leave the room without any information.
-
-The new room will be created with the user specified by the `new_room_user_id` parameter
-as room administrator and will contain a message explaining what happened. Users invited
-to the new room will have power level `-10` by default, and thus be unable to speak.
-
-If `block` is `True` it prevents new joins to the old room.
-
-This API will remove all trace of the old room from your database after removing
-all local users. If `purge` is `true` (the default), all traces of the old room will
-be removed from your database after removing all local users. If you do not want
-this to happen, set `purge` to `false`.
-Depending on the amount of history being purged a call to the API may take
-several minutes or longer.
-
-The local server will only have the power to move local user and room aliases to
-the new room. Users on other servers will be unaffected.
-
-The API is:
-
-```json
-POST /_synapse/admin/v1/rooms/<room_id>/delete
-```
-
-with a body of:
-```json
-{
-    "new_room_user_id": "@someuser:example.com",
-    "room_name": "Content Violation Notification",
-    "message": "Bad Room has been shutdown due to content violations on this server. Please review our Terms of Service.",
-    "block": true,
-    "purge": true
-}
-```
-
-To use it, you will need to authenticate by providing an ``access_token`` for a
-server admin: see [README.rst](README.rst).
-
-A response body like the following is returned:
-
-```json
-{
-    "kicked_users": [
-        "@foobar:example.com"
-    ],
-    "failed_to_kick_users": [],

-}
-```
-
-## Parameters
-
-The following parameters should be set in the URL:
-
-* `room_id` - The ID of the room.
-
-The following JSON body parameters are available:
-
-* `new_room_user_id` - Optional. If set, a new room will be created with this user ID
-      as the creator and admin, and all users in the old room will be moved into that
-      room. If not set, no new room will be created and the users will just be removed
-      from the old room. The user ID must be on the local server, but does not necessarily
-      have to belong to a registered user.
-* `room_name` - Optional. A string representing the name of the room that new users will be
-                invited to. Defaults to `Content Violation Notification`
-* `message` - Optional. A string containing the first message that will be sent as
-              `new_room_user_id` in the new room. Ideally this will clearly convey why the
-               original room was shut down. Defaults to `Sharing illegal content on this server
-               is not permitted and rooms in violation will be blocked.`
-* `block` - Optional. If set to `true`, this room will be added to a blocking list, preventing
-            future attempts to join the room. Defaults to `false`.
-* `purge` - Optional. If set to `true`, it will remove all traces of the room from your database.
-            Defaults to `true`.
-
-The JSON body must not be empty. The body must be at least `{}`.
-
-## Response
-
-The following fields are returned in the JSON response body:
-
-* `kicked_users` - An array of users (`user_id`) that were kicked.
-* `failed_to_kick_users` - An array of users (`user_id`) that that were not kicked.
-* `local_aliases` - An array of strings representing the local aliases that were migrated from
-                    the old room to the new.
-* `new_room_id` - A string representing the room ID of the new room.

-## Undoing room shutdowns
-
-*Note*: This guide may be outdated by the time you read it. By nature of room shutdowns being performed at the database level,
-the structure can and does change without notice.
-
-First, it's important to understand that a room shutdown is very destructive. Undoing a shutdown is not as simple as pretending it
-never happened - work has to be done to move forward instead of resetting the past. In fact, in some cases it might not be possible
-to recover at all:
-
-* If the room was invite-only, your users will need to be re-invited.
-* If the room no longer has any members at all, it'll be impossible to rejoin.
-* The first user to rejoin will have to do so via an alias on a different server.
-
-With all that being said, if you still want to try and recover the room:
-
-1. For safety reasons, shut down Synapse.
-2. In the database, run `DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';`
-   * For caution: it's recommended to run this in a transaction: `BEGIN; DELETE ...;`, verify you got 1 result, then `COMMIT;`.
-   * The room ID is the same one supplied to the shutdown room API, not the Content Violation room.
-3. Restart Synapse.
-
-You will have to manually handle, if you so choose, the following:
-
-* Aliases that would have been redirected to the Content Violation room.
-* Users that would have been booted from the room (and will have been force-joined to the Content Violation room).
-* Removal of the Content Violation room if desired.

-# Delegation
-
-By default, other homeservers will expect to be able to reach yours via
-your `server_name`, on port 8448. For example, if you set your `server_name`
-to `example.com` (so that your user names look like `@user:example.com`),
-other servers will try to connect to yours at `https://example.com:8448/`.
-
-Delegation is a Matrix feature allowing a homeserver admin to retain a
-`server_name` of `example.com` so that user IDs, room aliases, etc continue
-to look like `*:example.com`, whilst having federation traffic routed
-to a different server and/or port (e.g. `synapse.example.com:443`).
-
-## .well-known delegation
-
-To use this method, you need to be able to alter the
-`server_name` 's https server to serve the `/.well-known/matrix/server`
-URL. Having an active server (with a valid TLS certificate) serving your
-`server_name` domain is out of the scope of this documentation.
-
-The URL `https://<server_name>/.well-known/matrix/server` should
-return a JSON structure containing the key `m.server` like so:
-
-```json
-{
-    "m.server": "<synapse.server.name>[:<yourport>]"
-}
-```
-
-In our example, this would mean that URL `https://example.com/.well-known/matrix/server`
-should return:
-
-```json
-{
-    "m.server": "synapse.example.com:443"
-}
-```
-
-Note, specifying a port is optional. If no port is specified, then it defaults
-to 8448.
-
-With .well-known delegation, federating servers will check for a valid TLS
-certificate for the delegated hostname (in our example: `synapse.example.com`).
-
-## SRV DNS record delegation
-
-It is also possible to do delegation using a SRV DNS record. However, that is
-considered an advanced topic since it's a bit complex to set up, and `.well-known`
-delegation is already enough in most cases.
-
-However, if you really need it, you can find some documentation on how such a
-record should look like and how Synapse will use it in [the Matrix
-specification](https://matrix.org/docs/spec/server_server/latest#resolving-server-names).
-
-## Delegation FAQ
-
-### When do I need delegation?
-
-If your homeserver's APIs are accessible on the default federation port (8448)
-and the domain your `server_name` points to, you do not need any delegation.
-
-For instance, if you registered `example.com` and pointed its DNS A record at a
-fresh server, you could install Synapse on that host, giving it a `server_name`
-of `example.com`, and once a reverse proxy has been set up to proxy all requests
-sent to the port `8448` and serve TLS certificates for `example.com`, you
-wouldn't need any delegation set up.
-
-**However**, if your homeserver's APIs aren't accessible on port 8448 and on the
-domain `server_name` points to, you will need to let other servers know how to
-find it using delegation.
-
-### Do you still recommend against using a reverse proxy on the federation port?
-
-We no longer actively recommend against using a reverse proxy. Many admins will
-find it easier to direct federation traffic to a reverse proxy and manage their
-own TLS certificates, and this is a supported configuration.
-
-See [reverse_proxy.md](reverse_proxy.md) for information on setting up a
-reverse proxy.
-
-### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?
-
-This is no longer necessary. If you are using a reverse proxy for all of your
-TLS traffic, then you can set `no_tls: True` in the Synapse config.
-
-In that case, the only reason Synapse needs the certificate is to populate a legacy
-`tls_fingerprints` field in the federation API. This is ignored by Synapse 0.99.0
-and later, and the only time pre-0.99 Synapses will check it is when attempting to
-fetch the server keys - and generally this is delegated via `matrix.org`, which
-is running a modern version of Synapse.
-
-### Do I need the same certificate for the client and federation port?
-
-No. There is nothing stopping you from using different certificates,
-particularly if you are using a reverse proxy.

-# How to test CAS as a developer without a server
-
-The [django-mama-cas](https://github.com/jbittel/django-mama-cas) project is an
-easy to run CAS implementation built on top of Django.
-
-## Prerequisites
-
-1. Create a new virtualenv: `python3 -m venv <your virtualenv>`
-2. Activate your virtualenv: `source /path/to/your/virtualenv/bin/activate`
-3. Install Django and django-mama-cas:
-   ```
-   python -m pip install "django<3" "django-mama-cas==2.4.0"
-   ```
-4. Create a Django project in the current directory:
-   ```
-   django-admin startproject cas_test .
-   ```
-5. Follow the [install directions](https://django-mama-cas.readthedocs.io/en/latest/installation.html#configuring) for django-mama-cas
-6. Setup the SQLite database: `python manage.py migrate`
-7. Create a user:
-   ```
-   python manage.py createsuperuser
-   ```
-   1. Use whatever you want as the username and password.
-   2. Leave the other fields blank.
-8. Use the built-in Django test server to serve the CAS endpoints on port 8000:
-   ```
-   python manage.py runserver
-   ```
-
-You should now have a Django project configured to serve CAS authentication with
-a single user created.
-
-## Configure Synapse (and Riot) to use CAS
-
-1. Modify your `homeserver.yaml` to enable CAS and point it to your locally
-   running Django test server:
-   ```yaml
-   cas_config:
-     enabled: true
-     server_url: "http://localhost:8000"
-     service_url: "http://localhost:8081"
-     #displayname_attribute: name
-     #required_attributes:
-     #    name: value
-   ```
-2. Restart Synapse.
-
-Note that the above configuration assumes the homeserver is running on port 8081
-and that the CAS server is on port 8000, both on localhost.
-
-## Testing the configuration
-
-Then in Riot:
-
-1. Visit the login page with a Riot pointing at your homeserver.
-2. Click the Single Sign-On button.
-3. Login using the credentials created with `createsuperuser`.
-4. You should be logged in.
-
-If you want to repeat this process you'll need to manually logout first:
-
-1. http://localhost:8000/admin/
-2. Click "logout" in the top right.

-Some notes on how we use git
-============================
-
-On keeping the commit history clean
------------------------------------
-
-In an ideal world, our git commit history would be a linear progression of
-commits each of which contains a single change building on what came
-before. Here, by way of an arbitrary example, is the top of `git log --graph
-b2dba0607`:
-
-<img src="git/clean.png" alt="clean git graph" width="500px">
-
-Note how the commit comment explains clearly what is changing and why. Also
-note the *absence* of merge commits, as well as the absence of commits called
-things like (to pick a few culprits):
-[“pep8”](https://github.com/matrix-org/synapse/commit/84691da6c), [“fix broken
-test”](https://github.com/matrix-org/synapse/commit/474810d9d),
-[“oops”](https://github.com/matrix-org/synapse/commit/c9d72e457),
-[“typo”](https://github.com/matrix-org/synapse/commit/836358823), or [“Who's
-the president?”](https://github.com/matrix-org/synapse/commit/707374d5d).
-
-There are a number of reasons why keeping a clean commit history is a good
-thing:
-
- * From time to time, after a change lands, it turns out to be necessary to
-   revert it, or to backport it to a release branch. Those operations are
-   *much* easier when the change is contained in a single commit.
-
- * Similarly, it's much easier to answer questions like “is the fix for
-   `/publicRooms` on the release branch?” if that change consists of a single
-   commit.
-
- * Likewise: “what has changed on this branch in the last week?” is much
-   clearer without merges and “pep8” commits everywhere.
-
- * Sometimes we need to figure out where a bug got introduced, or some
-   behaviour changed. One way of doing that is with `git bisect`: pick an
-   arbitrary commit between the known good point and the known bad point, and
-   see how the code behaves. However, that strategy fails if the commit you
-   chose is the middle of someone's epic branch in which they broke the world
-   before putting it back together again.
-
-One counterargument is that it is sometimes useful to see how a PR evolved as
-it went through review cycles. This is true, but that information is always
-available via the GitHub UI (or via the little-known [refs/pull
-namespace](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally)).
-
-
-Of course, in reality, things are more complicated than that. We have release
-branches as well as `develop` and `master`, and we deliberately merge changes
-between them. Bugs often slip through and have to be fixed later. That's all
-fine: this not a cast-iron rule which must be obeyed, but an ideal to aim
-towards.
-
-Merges, squashes, rebases: wtf?
--------------------------------
-
-Ok, so that's what we'd like to achieve. How do we achieve it?
-
-The TL;DR is: when you come to merge a pull request, you *probably* want to
-“squash and merge”:
-
-![squash and merge](git/squash.png).
-
-(This applies whether you are merging your own PR, or that of another
-contributor.)
-
-“Squash and merge”<sup id="a1">[1](#f1)</sup> takes all of the changes in the
-PR, and bundles them into a single commit. GitHub gives you the opportunity to
-edit the commit message before you confirm, and normally you should do so,
-because the default will be useless (again: `* woops typo` is not a useful
-thing to keep in the historical record).
-
-The main problem with this approach comes when you have a series of pull
-requests which build on top of one another: as soon as you squash-merge the
-first PR, you'll end up with a stack of conflicts to resolve in all of the
-others. In general, it's best to avoid this situation in the first place by
-trying not to have multiple related PRs in flight at the same time. Still,
-sometimes that's not possible and doing a regular merge is the lesser evil.
-
-Another occasion in which a regular merge makes more sense is a PR where you've
-deliberately created a series of commits each of which makes sense in its own
-right. For example: [a PR which gradually propagates a refactoring operation
-through the codebase](https://github.com/matrix-org/synapse/pull/6837), or [a
-PR which is the culmination of several other
-PRs](https://github.com/matrix-org/synapse/pull/5987). In this case the ability
-to figure out when a particular change/bug was introduced could be very useful.
-
-Ultimately: **this is not a hard-and-fast-rule**. If in doubt, ask yourself “do
-each of the commits I am about to merge make sense in their own right”, but
-remember that we're just doing our best to balance “keeping the commit history
-clean” with other factors.
-
-Git branching model
--------------------
-
-A [lot](https://nvie.com/posts/a-successful-git-branching-model/)
-[of](http://scottchacon.com/2011/08/31/github-flow.html)
-[words](https://www.endoflineblog.com/gitflow-considered-harmful) have been
-written in the past about git branching models (no really, [a
-lot](https://martinfowler.com/articles/branching-patterns.html)). I tend to
-think the whole thing is overblown. Fundamentally, it's not that
-complicated. Here's how we do it.
-
-Let's start with a picture:
-
-![branching model](git/branches.jpg)
-
-It looks complicated, but it's really not. There's one basic rule: *anyone* is
-free to merge from *any* more-stable branch to *any* less-stable branch at
-*any* time<sup id="a2">[2](#f2)</sup>. (The principle behind this is that if a
-change is good enough for the more-stable branch, then it's also good enough go
-put in a less-stable branch.)
-
-Meanwhile, merging (or squashing, as per the above) from a less-stable to a
-more-stable branch is a deliberate action in which you want to publish a change
-or a set of changes to (some subset of) the world: for example, this happens
-when a PR is landed, or as part of our release process.
-
-So, what counts as a more- or less-stable branch? A little reflection will show
-that our active branches are ordered thus, from more-stable to less-stable:
-
- * `master` (tracks our last release).
- * `release-vX.Y.Z` (the branch where we prepare the next release)<sup
-   id="a3">[3](#f3)</sup>.
- * PR branches which are targeting the release.
- * `develop` (our "mainline" branch containing our bleeding-edge).
- * regular PR branches.
-
-The corollary is: if you have a bugfix that needs to land in both
-`release-vX.Y.Z` *and* `develop`, then you should base your PR on
-`release-vX.Y.Z`, get it merged there, and then merge from `release-vX.Y.Z` to
-`develop`. (If a fix lands in `develop` and we later need it in a
-release-branch, we can of course cherry-pick it, but landing it in the release
-branch first helps reduce the chance of annoying conflicts.)
