-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::

                            python-pip python-setuptools

 Installing prerequisites on Mac OS X::
 
     $ xcode-select --install
+    
+To install the synapse homeserver run::
+
+    $ pip install --user --process-dependency-links https://github.com/matrix-org/synapse/tarball/master
+
+This installs synapse, along with the libraries it uses, into

-Synapse uses NaCl (http://nacl.cr.yp.to/) for encryption and digital signatures.
+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.
