 ## 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.
+The preferred and easiest way to contribute changes to Matrix 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:
+**The single biggest thing you need to know is: please base your changes on
+the develop branch - *not* master.**
 
- * Please base your changes on the `develop` branch.
+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 follow the [code style requirements](#code-style).
+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.
 
- * Please include a [changelog entry](#changelog) with each PR.
+To run unit tests in a local development environment, you can use:
 
- * Please [sign off](#sign-off) your contribution.

 # Install the dependencies
-pip install -e ".[lint]"
+pip install -U black flake8 flake8-comprehensions isort
 
 # Run the linter script

 ```
 
 **Note that the script does not just test/check, but also reformats code, so you

-Almost all installations should opt to use PostgreSQL. Advantages include:

-Upgrading to v1.22.0
-====================
-
-ThirdPartyEventRules breaking changes
--------------------------------------
-
-This release introduces a backwards-incompatible change to modules making use of
-``ThirdPartyEventRules`` in Synapse. If you make use of a module defined under the
-``third_party_event_rules`` config option, please make sure it is updated to handle
-the below change:
-
-The ``http_client`` argument is no longer passed to modules as they are initialised. Instead,
-modules are expected to make use of the ``http_client`` property on the ``ModuleApi`` class.
-Modules are now passed a ``module_api`` argument during initialisation, which is an instance of
-``ModuleApi``. ``ModuleApi`` instances have a ``http_client`` property which acts the same as
-the ``http_client`` argument previously passed to ``ThirdPartyEventRules`` modules.
-
-Upgrading to v1.21.0
-====================
-
-Forwarding ``/_synapse/client`` through your reverse proxy
-----------------------------------------------------------
-
-The `reverse proxy documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/reverse_proxy.md>`_ has been updated
-to include reverse proxy directives for ``/_synapse/client/*`` endpoints. As the user password
-reset flow now uses endpoints under this prefix, **you must update your reverse proxy
-configurations for user password reset to work**.
-
-Additionally, note that the `Synapse worker documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/workers.md>`_ has been updated to
- state that the ``/_synapse/client/password_reset/email/submit_token`` endpoint can be handled
-by all workers. If you make use of Synapse's worker feature, please update your reverse proxy
-configuration to reflect this change.
-
-New HTML templates
-------------------
-
-A new HTML template,
-`password_reset_confirmation.html <https://github.com/matrix-org/synapse/blob/develop/synapse/res/templates/password_reset_confirmation.html>`_,
-has been added to the ``synapse/res/templates`` directory. If you are using a
-custom template directory, you may want to copy the template over and modify it.
-
-Note that as of v1.20.0, templates do not need to be included in custom template
-directories for Synapse to start. The default templates will be used if a custom
-template cannot be found.
-
-This page will appear to the user after clicking a password reset link that has
-been emailed to them.
-
-To complete password reset, the page must include a way to make a `POST`
-request to
-``/_synapse/client/password_reset/{medium}/submit_token``
-with the query parameters from the original link, presented as a URL-encoded form. See the file
-itself for more details.
-
-Updated Single Sign-on HTML Templates
--------------------------------------
-
-The ``saml_error.html`` template was removed from Synapse and replaced with the
-``sso_error.html`` template. If your Synapse is configured to use SAML and a
-custom ``sso_redirect_confirm_template_dir`` configuration then any customisations
-of the ``saml_error.html`` template will need to be merged into the ``sso_error.html``
-template. These templates are similar, but the parameters are slightly different:
-
-* The ``msg`` parameter should be renamed to ``error_description``.
-* There is no longer a ``code`` parameter for the response code.
-* A string ``error`` parameter is available that includes a short hint of why a
-  user is seeing the error page.
-
-Upgrading to v1.18.0
-====================
-
-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;
