+Subscription alternative
+========================
 
-🚀 Getting started
-==================
+Alternatively, for those that need an enterprise-ready solution, Element
+Server Suite (ESS) is `available as a subscription <https://element.io/pricing>`_.
+ESS builds on Synapse to offer a complete Matrix-based backend including the full
+`Admin Console product <https://element.io/enterprise-functionality/admin-console>`_,
+giving admins the power to easily manage an organization-wide
+deployment. It includes advanced identity management, auditing,
+moderation and data retention options as well as Long Term Support and
+SLAs. ESS can be used to support any Matrix-based frontend client.
 
-This component is developed and maintained by `Element <https://element.io>`_.
-It gets shipped as part of the **Element Server Suite (ESS)** which provides the
-official means of deployment.
+.. contents::
 
-ESS is a Matrix distribution from Element with focus on quality and ease of use.
-It ships a full Matrix stack tailored to the respective use case.
+🛠️ Installing and configuration
+===============================
 
-There are three editions of ESS:
+The Synapse documentation describes `how to install Synapse <https://element-hq.github.io/synapse/latest/setup/installation.html>`_. We recommend using
+`Docker images <https://element-hq.github.io/synapse/latest/setup/installation.html#docker-images-and-ansible-playbooks>`_ or `Debian packages from Matrix.org
+<https://element-hq.github.io/synapse/latest/setup/installation.html#matrixorg-packages>`_.
 
-- `ESS Community <https://github.com/element-hq/ess-helm>`_ - the free Matrix
-  distribution from Element tailored to small-/mid-scale, non-commercial
-  community use cases
-- `ESS Pro <https://element.io/server-suite>`_ - the commercial Matrix
-  distribution from Element for professional use
-- `ESS TI-M <https://element.io/server-suite/ti-messenger>`_ - a special version
-  of ESS Pro focused on the requirements of TI-Messenger Pro and ePA as
-  specified by the German National Digital Health Agency Gematik
+.. _federation:
+
+Synapse has a variety of `config options
+<https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html>`_
+which can be used to customise its behaviour after installation.
+There are additional details on how to `configure Synapse for federation here
+<https://element-hq.github.io/synapse/latest/federate.html>`_.
+
+.. _reverse-proxy:
+
+Using a reverse proxy with Synapse
+----------------------------------
+
+It is recommended to put a reverse proxy such as
+`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
+`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
+`Caddy <https://caddyserver.com/docs/quick-starts/reverse-proxy>`_,
+`HAProxy <https://www.haproxy.org/>`_ or
+`relayd <https://man.openbsd.org/relayd.8>`_ in front of Synapse. One advantage of
+doing so is that it means that you can expose the default https port (443) to
+Matrix clients without needing to run Synapse with root privileges.
+For information on configuring one, see `the reverse proxy docs
+<https://element-hq.github.io/synapse/latest/reverse_proxy.html>`_.
+
+Upgrading an existing Synapse
+-----------------------------
+
+The instructions for upgrading Synapse are in `the upgrade notes`_.
+Please check these instructions as upgrading may require extra steps for some
+versions of Synapse.
+
+.. _the upgrade notes: https://element-hq.github.io/synapse/develop/upgrade.html
 
 
-🛠️ Standalone installation and configuration
-============================================
+Platform dependencies
+---------------------
 
-The Synapse documentation describes `options for installing Synapse standalone
-<https://element-hq.github.io/synapse/latest/setup/installation.html>`_. See
-below for more useful documentation links.
+Synapse uses a number of platform dependencies such as Python and PostgreSQL,
+and aims to follow supported upstream versions. See the
+`deprecation policy <https://element-hq.github.io/synapse/latest/deprecation_policy.html>`_
+for more details.
 
-- `Synapse configuration options <https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html>`_
-- `Synapse configuration for federation <https://element-hq.github.io/synapse/latest/federate.html>`_
-- `Using a reverse proxy with Synapse <https://element-hq.github.io/synapse/latest/reverse_proxy.html>`_
-- `Upgrading Synapse <https://element-hq.github.io/synapse/develop/upgrade.html>`_
 
+Security note
+-------------
+
+Matrix serves raw, user-supplied data in some APIs -- specifically the `content
+repository endpoints`_.
+
+.. _content repository endpoints: https://matrix.org/docs/spec/client_server/latest.html#get-matrix-media-r0-download-servername-mediaid
+
+Whilst we make a reasonable effort to mitigate against XSS attacks (for
+instance, by using `CSP`_), a Matrix homeserver should not be hosted on a
+domain hosting other web applications. This especially applies to sharing
+the domain with Matrix web clients and other sensitive applications like
+webmail. See
+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.
+
+
+🧪 Testing a new installation
+=============================
+
+The easiest way to try out your new Synapse installation is by connecting to it
+from a web client.
+
+Unless you are running a test instance of Synapse on your local machine, in
+general, you will need to enable TLS support before you can successfully
+connect from a client: see
+`TLS certificates <https://element-hq.github.io/synapse/latest/setup/installation.html#tls-certificates>`_.
+
+An easy way to get started is to login or register via Element at
+https://app.element.io/#/login or https://app.element.io/#/register respectively.
+You will need to change the server you are logging into from ``matrix.org``
+and instead specify a Homeserver URL of ``https://<server_name>:8448``
+(or just ``https://<server_name>`` if you are using a reverse proxy).
+If you prefer to use another client, refer to our
+`client breakdown <https://matrix.org/ecosystem/clients/>`_.
+
+If all goes well you should at least be able to log in, create a room, and
+start sending messages.
+
+.. _`client-user-reg`:
+
+Registering a new user from a client
+------------------------------------
+
+By default, registration of new users via Matrix clients is disabled. To enable
+it:
+
+1. In the
+   `registration config section <https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#registration>`_
+   set ``enable_registration: true`` in ``homeserver.yaml``.
+2. Then **either**:
+
+   a. set up a `CAPTCHA <https://element-hq.github.io/synapse/latest/CAPTCHA_SETUP.html>`_, or
+   b. set ``enable_registration_without_verification: true`` in ``homeserver.yaml``.
+
+We **strongly** recommend using a CAPTCHA, particularly if your homeserver is exposed to
+the public internet. Without it, anyone can freely register accounts on your homeserver.
+This can be exploited by attackers to create spambots targetting the rest of the Matrix
+federation.
+
+Your new user name will be formed partly from the ``server_name``, and partly
+from a localpart you specify when you create the account. Your name will take
+the form of::
+
+    @localpart:my.domain.name
+
+(pronounced "at localpart on my dot domain dot name").
+
+As when logging in, you will need to specify a "Custom server".  Specify your
+desired ``localpart`` in the 'User name' box.

+🪪 Identity Servers
+===================
+
+Identity servers have the job of mapping email addresses and other 3rd Party
+IDs (3PIDs) to Matrix user IDs, as well as verifying the ownership of 3PIDs
+before creating that mapping.
+
+**They are not where accounts or credentials are stored - these live on home
+servers. Identity Servers are just for mapping 3rd party IDs to matrix IDs.**
+
+This process is very security-sensitive, as there is obvious risk of spam if it
+is too easy to sign up for Matrix accounts or harvest 3PID data. In the longer
+term, we hope to create a decentralised system to manage it (`matrix-doc #712
+<https://github.com/matrix-org/matrix-doc/issues/712>`_), but in the meantime,
+the role of managing trusted identity in the Matrix ecosystem is farmed out to
+a cluster of known trusted ecosystem partners, who run 'Matrix Identity
+Servers' such as `Sydent <https://github.com/matrix-org/sydent>`_, whose role
+is purely to authenticate and track 3PID logins and publish end-user public
+keys.
+
+You can host your own copy of Sydent, but this will prevent you reaching other
+users in the Matrix ecosystem via their email address, and prevent them finding
+you. We therefore recommend that you use one of the centralised identity servers
+at ``https://matrix.org`` or ``https://vector.im`` for now.
+
+To reiterate: the Identity server will only be used if you choose to associate
+an email address with your account, or send an invite to another user via their
+email address.

-ensure everything works at a holistic level.
-
-
-## Setup
-
-Nothing beyond a [normal Complement
-setup](https://github.com/matrix-org/complement?tab=readme-ov-file#running) (just Go and
-Docker).
-
-
-## Running tests
-
-Run tests from the [Complement](https://github.com/matrix-org/complement) repo:
-
-```shell
-# Run the tests
-./scripts-dev/complement.sh
-
-# To run a whole group of tests, you can specify part of the test path:
-scripts-dev/complement.sh ./tests/csapi/... -run TestRoomCreate
-# To run a specific test, you can specify the whole name structure:
-scripts-dev/complement.sh ./tests/csapi/... -run TestRoomCreate/Parallel/POST_/createRoom_makes_a_public_room
-# Generally though, the `-run` parameter accepts regex patterns, so you can match however you like:
-scripts-dev/complement.sh ./tests/... -run 'TestRoomCreate/Parallel/POST_/createRoom_makes_a_(.*)'
-```
-
-Typically, if you're developing the Synapse and Complement tests side-by-side, you will
-run something like this:
-
-```shell
-# To run a specific test
-COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh ./tests/csapi/... -run TestRoomCreate
-```
-
-
-### Running in-repo tests
-
-In-repo Complement tests are tests that are vendored into this project. We use the
-in-repo test suite to test Synapse specific behaviors like the admin API.
-
-To run the in-repo Complement tests, use the `--in-repo` command line argument.
-
-```shell
-# Run only a specific test package.
-# Note: test packages are relative to the `./complement` directory in this project
-./scripts-dev/complement.sh --in-repo ./tests/...
-
-# Similarly, you can also use `-run` to specify all or part of a specific test path to run
-scripts-dev/complement.sh --in-repo ./tests/... -run TestIntraShardFederation
-```

 ## Worker Service Examples in Docker Compose
 
 In order to start the Synapse container as a worker, you must specify an `entrypoint` that loads both the `homeserver.yaml` and the configuration for the worker (`synapse-generic-worker-1.yaml` in the example below). You must also include the worker type in the environment variable `SYNAPSE_WORKER` or alternatively pass `-m synapse.app.generic_worker` as part of the `entrypoint` after `"/start.py", "run"`).

-
-Set `SYNAPSE_ENABLE_METRICS=1` to configure `enable_metrics: true` and setup the
-`metrics` listener on the main and worker processes. Defaults to `0` (disabled). The
-main process will listen on port `19090` and workers on port `19091 + <worker index>`.
-
-When using `docker/Dockerfile-workers`, to ease the complexity with the metrics setup,
-we also have a [Prometheus HTTP service
-discovery](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#http_sd_config)
-endpoint available at `http://<synapse_container>:9469/metrics/service_discovery`.
-
-The metrics from each worker can also be accessed via
-`http://<synapse_container>:9469/metrics/worker/<worker_name>` which is what the service
-discovery response points to behind the scenes. This way, you only need to expose a
-single port (9469) to access all metrics.

-# Client-Server API Extensions
-
-Server administrators can set special account data to change how the Client-Server API behaves for
-their clients. Setting the account data, or having it already set, as a non-admin has no effect.
-
-All configuration options can be set through the `io.element.synapse.admin_client_config` global 
-account data on the admin's user account. 
-
-Example:
-```
-PUT /_matrix/client/v3/user/{adminUserId}/account_data/io.element.synapse.admin_client_config
-{
-    "return_soft_failed_events": true
-}
-```
-
-## See soft failed events
-
-Learn more about soft failure from [the spec](https://spec.matrix.org/v1.14/server-server-api/#soft-failure).
-
-To receive soft failed events in APIs like `/sync` and `/messages`, set `return_soft_failed_events`
-to `true` in the admin client config. When `false`, the normal behaviour of these endpoints is to
-exclude soft failed events.
-
-**Note**: If the policy server flagged the event as spam and that caused soft failure, that will be indicated
-in the event's `unsigned` content like so:
-
-```json
-{
-  "type": "m.room.message",
-  "other": "event_fields_go_here",
-  "unsigned": {
-    "io.element.synapse.soft_failed": true,
-    "io.element.synapse.policy_server_spammy": true
-  }
-}
-```
-
-Default: `false`
-
-## See events marked spammy by policy servers
-
-Learn more about policy servers from [MSC4284](https://github.com/matrix-org/matrix-spec-proposals/pull/4284).
-
-Similar to `return_soft_failed_events`, clients logged in with admin accounts can see events which were
-flagged by the policy server as spammy (and thus soft failed) by setting `return_policy_server_spammy_events`
-to `true`.
-
-`return_policy_server_spammy_events` may be `true` while `return_soft_failed_events` is `false` to only see
-policy server-flagged events. When `return_soft_failed_events` is `true` however, `return_policy_server_spammy_events`
-is always `true`.
-
-Events which were flagged by the policy will be flagged as `io.element.synapse.policy_server_spammy` in the
-event's `unsigned` content, like so:
-
-```json
-{
-  "type": "m.room.message",
-  "other": "event_fields_go_here",
-  "unsigned": {
-    "io.element.synapse.soft_failed": true,
-    "io.element.synapse.policy_server_spammy": true
-  }
-}
-```
-
-Default: `true` if `return_soft_failed_events` is `true`, otherwise `false`
