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:
- Chatrooms are distributed and do not exist on any single server. Rooms
can be found using aliases like ``#matrix:matrix.org`` or
``#test:localhost:8008`` or they can be ephemeral.
- 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:8008``.
- Matrix user IDs look like ``@matthew:matrix.org`` (although in the future
you will normally refer to yourself and others using a 3PID: email

WARNING
=======
**Synapse is currently in a state of rapid development, and not all features
are yet functional. Critically, some security features are still in
development, which means Synapse can *not* be considered secure or reliable at
this point.** For instance:
- **SSL Certificates used by server-server federation are not yet validated.**
- **Room permissions are not yet enforced on traffic received via federation.**
- **Homeservers do not yet cryptographically sign their events to avoid
tampering**
- Default configuration provides open signup to the service from the internet
Despite this, we believe Synapse is more than useful as a way for experimenting
and exploring Synapse, and the missing features will land shortly. **Until
then, please do *NOT* use Synapse for any remotely important or secure
communication.**
Quick Start
===========
System requirements:
- POSIX-compliant system (tested on Linux & OSX)
- Python 2.7
To get up and running:
- To simply play with an **existing** homeserver you can
just go straight to http://matrix.org/alpha.
- To run your own **private** homeserver on localhost:8008, generate a basic
config file: ``./synctl start`` will give you instructions on how to do this.
For this purpose, you can use 'localhost' or your hostname as a server name.
Once you've done so, running ``./synctl start`` again will start your private
home server. You will find a webclient running at http://localhost:8008.
Please use a recent Chrome or Firefox for now (or Safari if you don't need
VoIP support).
- To run a **public** homeserver and let it exchange messages with other
homeservers and participate in the global Matrix federation, you must expose
port 8448 to the internet and edit homeserver.yaml to specify server_name
(the public DNS entry for this server) and then run ``synctl start``. If you
changed the server_name, you may need to move the old database
(homeserver.db) out of the way first. Then come join ``#matrix:matrix.org``
and say hi! :)
For more detailed setup instructions, please see further down this document.
``#matrix:matrix.org`` is the official support room for Matrix, and can be
accessed by the web client at http://matrix.org/alpha or via an IRC bridge at
irc://irc.freenode.net/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!

Homeserver Installation
=======================
System requirements:
- POSIX-compliant system (tested on Linux & OSX)
- Python 2.7
Synapse is written in python but some of the libraries is uses are written in
C. So before we can install synapse itself we need a working C compiler and the
header files for python C extensions.
Installing prerequisites on Ubuntu::
Installing prerequisites on Ubuntu or Debian::
$ sudo apt-get install build-essential python2.7-dev libffi-dev \
python-pip python-setuptools
@ -137,8 +99,62 @@ Installing prerequisites on Ubuntu::
Installing prerequisites on Mac OS X::
$ xcode-select --install
To install the synapse homeserver run::
Synapse uses NaCl (http://nacl.cr.yp.to/) for encryption and digital signatures.
$ pip install --user --process-dependency-links https://github.com/matrix-org/synapse/tarball/master
This installs synapse, along with the libraries it uses, into
``$HOME/.local/lib/`` on Linux or ``$HOME/Library/Python/2.7/lib/`` on OSX.
Troubleshooting Installation
----------------------------
Synapse requires pip 1.7 or later, so if your OS provides too old a version and
you get errors about ``error: no such option: --process-dependency-links`` you
may need to manually upgrade it::
$ sudo pip install --upgrade pip
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
$ rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.:
$ pip install --user twisted
Running Your Homeserver
=======================
To actually run your new homeserver, pick a working directory for Synapse to run
(e.g. ``~/.synapse``), and::
$ mkdir ~/.synapse
$ cd ~/.synapse
$ # on Linux
$ ~/.local/bin/synctl start
$ # on OSX
$ ~/Library/Python/2.7/bin/synctl start
Troubleshooting Running
-----------------------
If ``synctl`` fails with ``pkg_resources.DistributionNotFound`` errors you may
need a newer version of setuptools than that provided by your OS.
$ sudo pip install setuptools --upgrade
If synapse fails with ``missing "sodium.h"`` crypto errors, you may need
to manually upgrade PyNaCL, as synapse uses NaCl (http://nacl.cr.yp.to/) for
encryption and digital signatures.
Unfortunately PyNACL currently has a few issues
(https://github.com/pyca/pynacl/issues/53) and
(https://github.com/pyca/pynacl/issues/79) that mean it may not install
