 =========================================================================
 
-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.
+
+We'd like to invite you to join #matrix:matrix.org (via
+https://matrix.org/docs/projects/try-matrix-now.html), run a homeserver, take a look
+at the `Matrix spec <https://matrix.org/docs/spec>`_, and experiment with the
+`APIs <https://matrix.org/docs/api>`_ and `Client SDKs
+<https://matrix.org/docs/projects/try-matrix-now.html#client-sdks>`_.
+
+Thanks for using Matrix!

+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.
-
-.. _the upgrade notes: https://matrix-org.github.io/synapse/develop/upgrade.html

-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.

+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, that are easiest
+to install using pip and a virtualenv::
+
+    python3 -m venv ./env
+    source ./env/bin/activate
+    pip install -e ".[all,dev]"
+
+This will run a process of downloading and installing all the needed
+dependencies into a virtual env. If any dependencies fail to install,
+try installing the failing modules individually::
+
+    pip install -e "module-name"
+
+We recommend using the demo which starts 3 federated instances running on ports `8080` - `8082`
+
+    ./demo/start.sh
+
+(to stop, you can use `./demo/stop.sh`)
+
+If you just want to start a single instance of the app and run it directly::
+
+    # Create the homeserver.yaml config once
+    python -m synapse.app.homeserver \
+      --server-name my.domain.name \
+      --config-path homeserver.yaml \
+      --generate-config \
+      --report-stats=[yes|no]
+
+    # Start the app
+    python -m synapse.app.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::
+
+    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.

+Need help? Join our community support room on Matrix:
+`#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.
