 =========================================================================
 
-Synapse is an open-source `Matrix <https://matrix.org/>`_ homeserver written and
-maintained by the Matrix.org Foundation. We began rapid development in 2014,
-reaching v1.0.0 in 2019. Development on Synapse and the Matrix protocol itself continues
-in earnest today.
-
-Briefly, Matrix is an open standard for communications on the internet, supporting
-federation, encryption and VoIP. Matrix.org has more to say about the `goals of the
-Matrix project <https://matrix.org/docs/guides/introduction>`_, and the `formal specification
-<https://spec.matrix.org/>`_ describes the technical details.

-Installing and configuration
-============================
+Introduction
+============
 
-The Synapse documentation describes `how to install Synapse <https://matrix-org.github.io/synapse/latest/setup/installation.html>`_. We recommend using
-`Docker images <https://matrix-org.github.io/synapse/latest/setup/installation.html#docker-images-and-ansible-playbooks>`_ or `Debian packages from Matrix.org
-<https://matrix-org.github.io/synapse/latest/setup/installation.html#matrixorg-packages>`_.
+Matrix is an ambitious new ecosystem for open federated Instant Messaging and
+VoIP.  The basics you need to know to get up and running are:
+
+- Everything in Matrix happens in a room.  Rooms are distributed and do not
+  exist on any single server.  Rooms can be located using convenience aliases
+  like ``#matrix:matrix.org`` or ``#test:localhost:8448``.
+
+- Matrix user IDs look like ``@matthew:matrix.org`` (although in the future
+  you will normally refer to yourself and others using a third party identifier
+  (3PID): email address, phone number, etc rather than manipulating Matrix user IDs)
+
+The overall architecture is::
+
+      client <----> homeserver <=====================> homeserver <----> client
+             https://somewhere.org/_matrix      https://elsewhere.net/_matrix
+
+``#matrix:matrix.org`` is the official support room for Matrix, and can be
+accessed by any client from https://matrix.org/docs/projects/try-matrix-now.html or
+via IRC bridge at irc://irc.libera.chat/matrix.
+
+Synapse is currently in rapid development, but as of version 0.5 we believe it
+is sufficiently stable to be run as an internet-facing service for real usage!
+
+About Matrix
+============
+
+Matrix specifies a set of pragmatic RESTful HTTP JSON APIs as an open standard,
+which handle:
+
+- Creating and managing fully distributed chat rooms with no
+  single points of control or failure
+- Eventually-consistent cryptographically secure synchronisation of room
+  state across a global open network of federated servers and services
+- Sending and receiving extensible messages in a room with (optional)
+  end-to-end encryption
+- Inviting, joining, leaving, kicking, banning room members
+- Managing user accounts (registration, login, logout)
+- Using 3rd Party IDs (3PIDs) such as email addresses, phone numbers,
+  Facebook accounts to authenticate, identify and discover users on Matrix.
+- Placing 1:1 VoIP and Video calls
+
+These APIs are intended to be implemented on a wide range of servers, services
+and clients, letting developers build messaging and VoIP functionality on top
+of the entirely open Matrix ecosystem rather than using closed or proprietary
+solutions. The hope is for Matrix to act as the building blocks for a new
+generation of fully open and interoperable messaging and VoIP apps for the
+internet.
+
+Synapse is a Matrix "homeserver" implementation developed by the matrix.org core
+team, written in Python 3/Twisted.
+
+In Matrix, every user runs one or more Matrix clients, which connect through to
+a Matrix homeserver. The homeserver stores all their personal chat history and
+user account information - much as a mail client connects through to an
+IMAP/SMTP server. Just like email, you can either run your own Matrix
+homeserver and control and own your own communications and history or use one
+hosted by someone else (e.g. matrix.org) - there is no single point of control
+or mandatory service provider in Matrix, unlike WhatsApp, Facebook, Hangouts,
+etc.
+

+Synapse Installation
+====================
 
 .. _federation:
 
-Synapse has a variety of `config options
-<https://matrix-org.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://matrix-org.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://matrix-org.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.

-Platform dependencies
----------------------
+Connecting to Synapse from a client
+===================================
 
-Synapse uses a number of platform dependencies such as Python and PostgreSQL,
-and aims to follow supported upstream versions. See the
-`deprecation policy <https://matrix-org.github.io/synapse/latest/deprecation_policy.html>`_
-for more details.
+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://matrix-org.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/docs/projects/clients-matrix>`_.
+
+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, specify ``enable_registration: true`` in ``homeserver.yaml``. (It is then
+recommended to also set up CAPTCHA - see `<docs/CAPTCHA_SETUP.md>`_.)
+
+Once ``enable_registration`` is set to ``true``, it is possible to register a
+user via a Matrix client.
+
+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.

 `#synapse-dev:matrix.org <https://matrix.to/#/#synapse-dev:matrix.org>`_, featuring real humans!
 
 
+Quick start
+-----------
+
+Before setting up a development environment for synapse, make sure you have the
+system dependencies (such as the python header files) installed - see
+`Platform-specific prerequisites <https://matrix-org.github.io/synapse/latest/setup/installation.html#platform-specific-prerequisites>`_.
+
+To check out a synapse for development, clone the git repo into a working
+directory of your choice::
+
+    git clone https://github.com/matrix-org/synapse.git
+    cd synapse
+
+Synapse has a number of external dependencies. We maintain a fixed development
+environment using `Poetry <https://python-poetry.org/>`_. First, install poetry. We recommend::
+
+    pip install --user pipx
+    pipx install poetry
+
+as described `here <https://python-poetry.org/docs/#installing-with-pipx>`_.
+(See `poetry's installation docs <https://python-poetry.org/docs/#installation>`_
+for other installation methods.) Then ask poetry to create a virtual environment
+from the project and install Synapse's dependencies::
+
+    poetry install --extras "all test"
+
+This will run a process of downloading and installing all the needed
+dependencies into a virtual env.
+
+We recommend using the demo which starts 3 federated instances running on ports `8080` - `8082`::
+
+    poetry run ./demo/start.sh
+
+(to stop, you can use ``poetry run ./demo/stop.sh``)
+
+See the `demo documentation <https://matrix-org.github.io/synapse/develop/development/demo.html>`_
+for more information.
+
+If you just want to start a single instance of the app and run it directly::
+
+    # Create the homeserver.yaml config once
+    poetry run synapse_homeserver \
+      --server-name my.domain.name \
+      --config-path homeserver.yaml \
+      --generate-config \
+      --report-stats=[yes|no]
+
+    # Start the app
+    poetry run synapse_homeserver --config-path homeserver.yaml
+
+
+Running the unit tests
+----------------------
+
+After getting up and running, you may wish to run Synapse's unit tests to
+check that everything is installed correctly::
+
+    poetry run trial tests
+
+This should end with a 'PASSED' result (note that exact numbers will
+differ)::
+
+    Ran 1337 tests in 716.064s
+
+    PASSED (skips=15, successes=1322)
+
+For more tips on running the unit tests, like running a specific test or
+to see the logging output, see the `CONTRIBUTING doc <CONTRIBUTING.md#run-the-unit-tests>`_.
+
+
+Running the Integration Tests
+-----------------------------
+
+Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
+a Matrix homeserver integration testing suite, which uses HTTP requests to
+access the API as a Matrix client would. It is able to run Synapse directly from
+the source tree, so installation of the server is not required.
+
+Testing with SyTest is recommended for verifying that changes related to the
+Client-Server API are functioning correctly. See the `SyTest installation
+instructions <https://github.com/matrix-org/sytest#installing>`_ for details.
+
+
+Platform dependencies
+=====================

+`#synapse:matrix.org <https://matrix.to/#/#synapse:matrix.org>`_
+
+Running out of File Handles
+---------------------------
+
+If synapse runs out of file handles, it typically fails badly - live-locking
+at 100% CPU, and/or failing to accept new TCP connections (blocking the
+connecting client).  Matrix currently can legitimately use a lot of file handles,
+thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
+servers.  The first time a server talks in a room it will try to connect
+simultaneously to all participating servers, which could exhaust the available
+file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
+to respond. (We need to improve the routing algorithm used to be better than
+full mesh, but as of March 2019 this hasn't happened yet).
+
+If you hit this failure mode, we recommend increasing the maximum number of
+open file handles to be at least 4096 (assuming a default of 1024 or 256).
+This is typically done by editing ``/etc/security/limits.conf``
+
+Separately, Synapse may leak file handles if inbound HTTP requests get stuck
+during processing - e.g. blocked behind a lock or talking to a remote server etc.
+This is best diagnosed by matching up the 'Received request' and 'Processed request'
+log lines and looking for any 'Processed request' lines which take more than
+a few seconds to execute. Please let us know at #synapse:matrix.org if
+you see this failure mode so we can help debug it, however.
+
+Help!! Synapse is slow and eats all my RAM/CPU!
+-----------------------------------------------
+
+First, ensure you are running the latest version of Synapse, using Python 3
+with a PostgreSQL database.
+
+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 ``SYNAPSE_CACHE_FACTOR`` 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.
+
+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.
+
+Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
+improvement in overall memory use, and especially in terms of giving back
+RAM to the OS. To use it, the library must simply be put in the
+LD_PRELOAD environment variable when launching Synapse. On Debian, this
+can be done by installing the ``libjemalloc1`` package and adding this
+line to ``/etc/default/matrix-synapse``::
+
+    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
+
+This can make a significant difference on Python 2.7 - it's unclear how
+much of an improvement it provides on Python 3.x.
+
+If you're encountering high CPU use by the Synapse process itself, you
+may be affected by a bug with presence tracking that leads to a
+massive excess of outgoing federation requests (see `discussion
+<https://github.com/matrix-org/synapse/issues/3971>`_). If metrics
+indicate that your server is also issuing far more outgoing federation
+requests than can be accounted for by your users' activity, this is a
+likely cause. The misbehavior can be worked around by setting
+the following in the Synapse config file:
+
+.. code-block:: yaml
+
+   presence:
+       enabled: false
+
+People can't accept room invitations from me
+--------------------------------------------
+
+The typical failure mode here is that you send an invitation to someone
+to join a room or direct chat, but when they go to accept it, they get an
+error (typically along the lines of "Invalid signature"). They might see
+something like the following in their logs::
+
+    2019-09-11 19:32:04,271 - synapse.federation.transport.server - 288 - WARNING - GET-11752 - authenticate_request failed: 401: Invalid signature for server <server> with key ed25519:a_EqML: Unable to verify signature for <server>
+
+This is normally caused by a misconfiguration in your reverse-proxy. See
+`<docs/reverse_proxy.md>`_ and double-check that your settings are correct.

-
-The Room Messages admin API allows server admins to get all messages

-that allow for filtering and ordering the returned list. This API supports pagination.
-
-To use it, you will need to authenticate by providing an `access_token`
-for a server admin: see [Admin API](../usage/administration/admin_api).
-
-This endpoint mirrors the [Matrix Spec defined Messages API](https://spec.matrix.org/v1.1/client-server-api/#get_matrixclientv3roomsroomidmessages).
-
-The API is:
-```
-GET /_synapse/admin/v1/rooms/<room_id>/messages
-```
-
-**Parameters**
-
-The following path parameters are required:
-
-* `room_id` - The ID of the room you wish you fetch messages from.
-
-The following query parameters are available:
-
-* `from` (required) - The token to start returning events from. This token can be obtained from a prev_batch
-  or next_batch token returned by the /sync endpoint, or from an end token returned by a previous request to this endpoint.
-* `to` - The token to spot returning events at.
-* `limit` - The maximum number of events to return. Defaults to `10`.
-* `filter` - A JSON RoomEventFilter to filter returned events with.
-* `dir` - The direction to return events from. Either `f` for forwards or `b` for backwards. Setting
-  this value to `b` will reverse the above sort order. Defaults to `f`.
-
-**Response**
-
-The following fields are possible in the JSON response body:
-
-* `chunk` - A list of room events. The order depends on the dir parameter.
-          Note that an empty chunk does not necessarily imply that no more events are available. Clients should continue to paginate until no end property is returned.
-* `end` - A token corresponding to the end of chunk. This token can be passed back to this endpoint to request further events.
-          If no further events are available, this property is omitted from the response.
-* `start` - A token corresponding to the start of chunk.
-* `state` - A list of state events relevant to showing the chunk.

-the chain contains a path `E -> F` or a path `F -> E`. This forces a chain to be
-linear (without forks), e.g. `E -> F -> G -> ... -> H`. Each event in the chain
-is given a *sequence number* local to that chain. The oldest event `E` in the
-chain has sequence number 1. If `E` has a child `F` in the chain, then `F` has
-sequence number 2. If `E` has a grandchild `G` in the chain, then `G` has
-sequence number 3; and so on.

-Synapse ensures that each persisted event belongs to exactly one chain, and

-two events with the same `event_id` (in the same or different rooms). After room

-# coturn TURN server
-
-The following sections describe how to install [coturn](<https://github.com/coturn/coturn>) (which implements the TURN REST API).
-
-## `coturn` setup
-
-### Initial installation
-
-The TURN daemon `coturn` is available from a variety of sources such as native package managers, or installation from source.
-
-#### Debian and Ubuntu based distributions
-
-Just install the debian package:
-
-```sh
-sudo apt install coturn
-```
-
-This will install and start a systemd service called `coturn`.
-
-#### Source installation
-
-1. Download the [latest release](https://github.com/coturn/coturn/releases/latest) from github.  Unpack it and `cd` into the directory.
-
-1.  Configure it:
-
-    ```sh
-    ./configure
-    ```
-
-    You may need to install `libevent2`: if so, you should do so in
-    the way recommended by your operating system. You can ignore
-    warnings about lack of database support: a database is unnecessary
-    for this purpose.
-
-1.  Build and install it:
-
-    ```sh
-    make
-    sudo make install
-    ```
-
-### Configuration
-
-1.  Create or edit the config file in `/etc/turnserver.conf`. The relevant
-    lines, with example values, are:
-
-    ```
-    use-auth-secret
-    static-auth-secret=[your secret key here]
-    realm=turn.myserver.org
-    ```
-
-    See `turnserver.conf` for explanations of the options. One way to generate
-    the `static-auth-secret` is with `pwgen`:
-
-    ```sh
-    pwgen -s 64 1
-    ```
-
-    A `realm` must be specified, but its value is somewhat arbitrary. (It is
-    sent to clients as part of the authentication flow.) It is conventional to
-    set it to be your server name.
-
-1.  You will most likely want to configure `coturn` to write logs somewhere. The
-    easiest way is normally to send them to the syslog:
-
-    ```sh
-    syslog
-    ```
-
-    (in which case, the logs will be available via `journalctl -u coturn` on a
-    systemd system). Alternatively, `coturn` can be configured to write to a
-    logfile - check the example config file supplied with `coturn`.
-
-1.  Consider your security settings. TURN lets users request a relay which will
-    connect to arbitrary IP addresses and ports. The following configuration is
-    suggested as a minimum starting point:
-
-    ```
-    # VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
-    no-tcp-relay
-
-    # don't let the relay ever try to connect to private IP address ranges within your network (if any)
-    # given the turn server is likely behind your firewall, remember to include any privileged public IPs too.

-
-    # consider whether you want to limit the quota of relayed streams per user (or total) to avoid risk of DoS.
-    user-quota=12 # 4 streams per video call, so 12 streams = 3 simultaneous relayed calls per user.
-    total-quota=1200
-    ```
-
-1.  Also consider supporting TLS/DTLS. To do this, add the following settings
-    to `turnserver.conf`:
-
-    ```
-    # TLS certificates, including intermediate certs.
-    # For Let's Encrypt certificates, use `fullchain.pem` here.
-    cert=/path/to/fullchain.pem
-
-    # TLS private key file
-    pkey=/path/to/privkey.pem
-
-    # Ensure the configuration lines that disable TLS/DTLS are commented-out or removed
-    #no-tls
-    #no-dtls
-    ```
-
-    In this case, replace the `turn:` schemes in the `turn_uris` settings below
-    with `turns:`.
-
-    We recommend that you only try to set up TLS/DTLS once you have set up a
-    basic installation and got it working.
-
-    NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will
-    not work with any Matrix client that uses Chromium's WebRTC library. This
-    currently includes Element Android & iOS; for more details, see their
-    [respective](https://github.com/vector-im/element-android/issues/1533)
-    [issues](https://github.com/vector-im/element-ios/issues/2712) as well as the underlying
-    [WebRTC issue](https://bugs.chromium.org/p/webrtc/issues/detail?id=11710).
-    Consider using a ZeroSSL certificate for your TURN server as a working alternative.
-
-1.  Ensure your firewall allows traffic into the TURN server on the ports
-    you've configured it to listen on (By default: 3478 and 5349 for TURN
-    traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
-    for the UDP relay.)
-
-1.  If your TURN server is behind NAT, the NAT gateway must have an external,
-    publicly-reachable IP address. You must configure `coturn` to advertise that
-    address to connecting clients:
-
-    ```
-    external-ip=EXTERNAL_NAT_IPv4_ADDRESS
-    ```
-
-    You may optionally limit the TURN server to listen only on the local
-    address that is mapped by NAT to the external address:
-
-    ```
-    listening-ip=INTERNAL_TURNSERVER_IPv4_ADDRESS
-    ```
-
-    If your NAT gateway is reachable over both IPv4 and IPv6, you may
-    configure `coturn` to advertise each available address:
-
-    ```
-    external-ip=EXTERNAL_NAT_IPv4_ADDRESS
-    external-ip=EXTERNAL_NAT_IPv6_ADDRESS
-    ```
-
-    When advertising an external IPv6 address, ensure that the firewall and
-    network settings of the system running your TURN server are configured to
-    accept IPv6 traffic, and that the TURN server is listening on the local
-    IPv6 address that is mapped by NAT to the external IPv6 address.
-
-1.  (Re)start the turn server:
-
-    * If you used the Debian package (or have set up a systemd unit yourself):
-      ```sh
-      sudo systemctl restart coturn
-      ```
-
-    * If you built from source:
-
-      ```sh
-      /usr/local/bin/turnserver -o
-      ```

-# eturnal TURN server
-
-The following sections describe how to install [eturnal](<https://github.com/processone/eturnal>) 
-(which implements the TURN REST API).
-
-## `eturnal` setup
-
-### Initial installation
-
-The `eturnal` TURN server implementation is available from a variety of sources 
-such as native package managers, binary packages, installation from source or 
-[container image](https://eturnal.net/documentation/code/docker.html). They are 
-all described [here](https://github.com/processone/eturnal#installation).
-
-Quick-Test instructions in a [Linux Shell](https://github.com/processone/eturnal/blob/master/QUICK-TEST.md) 
-or with [Docker](https://github.com/processone/eturnal/blob/master/docker-k8s/QUICK-TEST.md) 
-are available as well.
-
-### Configuration
-
-After installation, `eturnal` usually ships a [default configuration file](https://github.com/processone/eturnal/blob/master/config/eturnal.yml) 
-here: `/etc/eturnal.yml` (and, if not found there, there is a backup file here: 
-`/opt/eturnal/etc/eturnal.yml`). It uses the (indentation-sensitive!) [YAML](https://en.wikipedia.org/wiki/YAML) 
-format. The file contains further explanations.
-
-Here are some hints how to configure eturnal on your [host machine](https://github.com/processone/eturnal#configuration) 
-or when using e.g. [Docker](https://eturnal.net/documentation/code/docker.html).
-You may also further deep dive into the [reference documentation](https://eturnal.net/documentation/).
-
-`eturnal` runs out of the box with the default configuration. To enable TURN and 
-to integrate it with your homeserver, some aspects in `eturnal`'s default configuration file 
-must be edited:
-
-1.  Homeserver's [`turn_shared_secret`](../../usage/configuration/config_documentation.md#turn_shared_secret) 
-    and eturnal's shared `secret` for authentication
-
-    Both need to have the same value. Uncomment and adjust this line in `eturnal`'s 
-    configuration file:
-
-    ```yaml
-    secret: "long-and-cryptic"     # Shared secret, CHANGE THIS.
-    ```
-
-    One way to generate a `secret` is with `pwgen`:
-
-    ```sh
-    pwgen -s 64 1
-    ```
-
-1.  Public IP address
-
-    If your TURN server is behind NAT, the NAT gateway must have an external,
-    publicly-reachable IP address. `eturnal` tries to autodetect the public IP address, 
-    however, it may also be configured by uncommenting and adjusting this line, so 
-    `eturnal` advertises that address to connecting clients:
-
-    ```yaml
-    relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address.
-    ```
-
-    If your NAT gateway is reachable over both IPv4 and IPv6, you may
-    configure `eturnal` to advertise each available address:
-
-    ```yaml
-    relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address.
-    relay_ipv6_addr: "2001:db8::4" # The server's public IPv6 address (optional).
-    ```
-
-    When advertising an external IPv6 address, ensure that the firewall and
-    network settings of the system running your TURN server are configured to
-    accept IPv6 traffic, and that the TURN server is listening on the local
-    IPv6 address that is mapped by NAT to the external IPv6 address.
-
-1.  Logging
-
-    If `eturnal` was started by systemd, log files are written into the
-    `/var/log/eturnal` directory by default. In order to log to the [journal](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html)
-    instead, the `log_dir` option can be set to `stdout` in the configuration file.
-
-1.  Security considerations
-
-    Consider your security settings. TURN lets users request a relay which will
-    connect to arbitrary IP addresses and ports. The following configuration is
-    suggested as a minimum starting point, [see also the official documentation](https://eturnal.net/documentation/#blacklist):
-
-    ```yaml
-    ## Reject TURN relaying from/to the following addresses/networks:
-    blacklist:                 # This is the default blacklist.
-        - "127.0.0.0/8"        # IPv4 loopback.
-        - "::1"                # IPv6 loopback.
-        - recommended          # Expands to a number of networks recommended to be
-                               # blocked, but includes private networks. Those
-                               # would have to be 'whitelist'ed if eturnal serves
-                               # local clients/peers within such networks.
-    ```
-
-    To whitelist IP addresses or specific (private) networks, you need to **add** a 
-    whitelist part into the configuration file, e.g.:
-
-    ```yaml
-    whitelist:
-        - "192.168.0.0/16"
-        - "203.0.113.113"
-        - "2001:db8::/64"
-    ```
-
-    The more specific, the better.
-
-1.  TURNS (TURN via TLS/DTLS)
-
-    Also consider supporting TLS/DTLS. To do this, adjust the following settings
-    in the `eturnal.yml` configuration file (TLS parts should not be commented anymore):
-
-    ```yaml
-    listen:
-        - ip: "::"
-          port: 3478
-          transport: udp
-        - ip: "::"
-          port: 3478
-          transport: tcp
-        - ip: "::"
-          port: 5349
-          transport: tls
-
-    ## TLS certificate/key files (must be readable by 'eturnal' user!):
-    tls_crt_file: /etc/eturnal/tls/crt.pem
-    tls_key_file: /etc/eturnal/tls/key.pem
-    ```
-
-    In this case, replace the `turn:` schemes in homeserver's `turn_uris` settings
-    with `turns:`. More is described [here](../../usage/configuration/config_documentation.md#turn_uris).
-
-    We recommend that you only try to set up TLS/DTLS once you have set up a
-    basic installation and got it working.
-
-    NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will
-    not work with any Matrix client that uses Chromium's WebRTC library. This
-    currently includes Element Android & iOS; for more details, see their
-    [respective](https://github.com/vector-im/element-android/issues/1533)
-    [issues](https://github.com/vector-im/element-ios/issues/2712) as well as the underlying
-    [WebRTC issue](https://bugs.chromium.org/p/webrtc/issues/detail?id=11710).
-    Consider using a ZeroSSL certificate for your TURN server as a working alternative.
-
-1.  Firewall
-
-    Ensure your firewall allows traffic into the TURN server on the ports
-    you've configured it to listen on (By default: 3478 and 5349 for TURN
-    traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
-    for the UDP relay.)
-
-1.  Reload/ restarting `eturnal`

-to query how many active sessions exist, to change logging behaviour and so on.

-This documentation provides two TURN server configuration examples:
-
-* [coturn](setup/turn/coturn.md)
-* [eturnal](setup/turn/eturnal.md)
+The following sections describe how to install [coturn](<https://github.com/coturn/coturn>) (which implements the TURN REST API) and integrate it with synapse.
 
 ## Requirements
 
-For TURN relaying to work, the TURN service must be hosted on a server/endpoint with a public IP.
+For TURN relaying with `coturn` to work, it must be hosted on a server/endpoint with a public IP.
 
 Hosting TURN behind NAT requires port forwaring and for the NAT gateway to have a public IP.
 However, even with appropriate configuration, NAT is known to cause issues and to often not work.
 
-Afterwards, the homeserver needs some further configuration.
+## `coturn` setup
+
+### Initial installation
+
+The TURN daemon `coturn` is available from a variety of sources such as native package managers, or installation from source.
+
+#### Debian installation
+
+Just install the debian package:
+
+```sh
+apt install coturn
+```
+
+This will install and start a systemd service called `coturn`.
+
+#### Source installation
+
+1. Download the [latest release](https://github.com/coturn/coturn/releases/latest) from github.  Unpack it and `cd` into the directory.
+
+1.  Configure it:
+
+    ```sh
+    ./configure
+    ```
+
+    You may need to install `libevent2`: if so, you should do so in
+    the way recommended by your operating system. You can ignore
+    warnings about lack of database support: a database is unnecessary
+    for this purpose.
+
+1.  Build and install it:
+
+    ```sh
+    make
+    make install
+    ```
+
+### Configuration
+
+1.  Create or edit the config file in `/etc/turnserver.conf`. The relevant
+    lines, with example values, are:
+
+    ```
+    use-auth-secret
+    static-auth-secret=[your secret key here]
+    realm=turn.myserver.org
+    ```
+
+    See `turnserver.conf` for explanations of the options. One way to generate
+    the `static-auth-secret` is with `pwgen`:
+
+    ```sh
+    pwgen -s 64 1
+    ```
+
+    A `realm` must be specified, but its value is somewhat arbitrary. (It is
+    sent to clients as part of the authentication flow.) It is conventional to
+    set it to be your server name.
+
+1.  You will most likely want to configure coturn to write logs somewhere. The
+    easiest way is normally to send them to the syslog:
+
+    ```sh
+    syslog
+    ```
+
+    (in which case, the logs will be available via `journalctl -u coturn` on a
+    systemd system). Alternatively, coturn can be configured to write to a
+    logfile - check the example config file supplied with coturn.
+
+1.  Consider your security settings. TURN lets users request a relay which will
+    connect to arbitrary IP addresses and ports. The following configuration is
+    suggested as a minimum starting point:
+
+    ```
+    # VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
+    no-tcp-relay
+
+    # don't let the relay ever try to connect to private IP address ranges within your network (if any)
+    # given the turn server is likely behind your firewall, remember to include any privileged public IPs too.

+    allowed-peer-ip=10.0.0.1
+
+    # consider whether you want to limit the quota of relayed streams per user (or total) to avoid risk of DoS.
+    user-quota=12 # 4 streams per video call, so 12 streams = 3 simultaneous relayed calls per user.
+    total-quota=1200
+    ```
+
+1.  Also consider supporting TLS/DTLS. To do this, add the following settings
+    to `turnserver.conf`:
+
+    ```
+    # TLS certificates, including intermediate certs.
+    # For Let's Encrypt certificates, use `fullchain.pem` here.
+    cert=/path/to/fullchain.pem
+
+    # TLS private key file
+    pkey=/path/to/privkey.pem
+
+    # Ensure the configuration lines that disable TLS/DTLS are commented-out or removed
+    #no-tls
+    #no-dtls
+    ```
+
+    In this case, replace the `turn:` schemes in the `turn_uris` settings below
+    with `turns:`.
+
+    We recommend that you only try to set up TLS/DTLS once you have set up a
+    basic installation and got it working.
+
+    NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will
+    not work with any Matrix client that uses Chromium's WebRTC library. This
+    currently includes Element Android & iOS; for more details, see their
+    [respective](https://github.com/vector-im/element-android/issues/1533)
+    [issues](https://github.com/vector-im/element-ios/issues/2712) as well as the underlying
+    [WebRTC issue](https://bugs.chromium.org/p/webrtc/issues/detail?id=11710).
+    Consider using a ZeroSSL certificate for your TURN server as a working alternative.
+
+1.  Ensure your firewall allows traffic into the TURN server on the ports
+    you've configured it to listen on (By default: 3478 and 5349 for TURN
+    traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
+    for the UDP relay.)
+
+1.  If your TURN server is behind NAT, the NAT gateway must have an external,
+    publicly-reachable IP address. You must configure coturn to advertise that
+    address to connecting clients:
+
+    ```
+    external-ip=EXTERNAL_NAT_IPv4_ADDRESS
+    ```
+
+    You may optionally limit the TURN server to listen only on the local
+    address that is mapped by NAT to the external address:
+
+    ```
+    listening-ip=INTERNAL_TURNSERVER_IPv4_ADDRESS
+    ```
+
+    If your NAT gateway is reachable over both IPv4 and IPv6, you may
+    configure coturn to advertise each available address:
+
+    ```
+    external-ip=EXTERNAL_NAT_IPv4_ADDRESS
+    external-ip=EXTERNAL_NAT_IPv6_ADDRESS
+    ```
+
+    When advertising an external IPv6 address, ensure that the firewall and
+    network settings of the system running your TURN server are configured to
+    accept IPv6 traffic, and that the TURN server is listening on the local
+    IPv6 address that is mapped by NAT to the external IPv6 address.
+
+1.  (Re)start the turn server:
+
+    * If you used the Debian package (or have set up a systemd unit yourself):
+      ```sh
+      systemctl restart coturn
+      ```
+
+    * If you installed from source:
+
+      ```sh
+      bin/turnserver -o
+      ```
 
 ## Synapse setup
 
 Your homeserver configuration file needs the following extra keys:
 
-1.  [`turn_uris`](usage/configuration/config_documentation.md#turn_uris)
-2.  [`turn_shared_secret`](usage/configuration/config_documentation.md#turn_shared_secret)
-3.  [`turn_user_lifetime`](usage/configuration/config_documentation.md#turn_user_lifetime)
-4.  [`turn_allow_guests`](usage/configuration/config_documentation.md#turn_allow_guests)
+1.  "`turn_uris`": This needs to be a yaml list of public-facing URIs
+    for your TURN server to be given out to your clients. Add separate
+    entries for each transport your TURN server supports.
+2.  "`turn_shared_secret`": This is the secret shared between your
+    homeserver and your TURN server, so you should set it to the same
+    string you used in turnserver.conf.
+3.  "`turn_user_lifetime`": This is the amount of time credentials
+    generated by your homeserver are valid for (in milliseconds).
+    Shorter times offer less potential for abuse at the expense of
+    increased traffic between web clients and your homeserver to
+    refresh credentials. The TURN REST API specification recommends
+    one day (86400000).
+4.  "`turn_allow_guests`": Whether to allow guest users to use the
+    TURN server. This is enabled by default, as otherwise VoIP will
+    not work reliably for guests. However, it does introduce a
+    security risk as it lets guests connect to arbitrary endpoints
+    without having gone through a CAPTCHA or similar to register a
+    real account.
 
 As an example, here is the relevant section of the config file for `matrix.org`. The
 `turn_uris` are appropriate for TURN servers listening on the default ports, with no TLS.
