+Quick Start
+===========
+
+The basics you need to know about Matrix are:
+
+    - Chatrooms look like ``#matrix:matrix.org`` or ``#test:localhost:8080``
+    
+    - Matrix user IDs look like ``@matthew:matrix.org`` (although in the future
+      you will normally refer to yourself and others using a 3PID: email
+      address, phone number, etc rather than manipulating matrix user IDs)
+      
+    - To simply play with an **existing** homeserver (e.g. matrix.org), you can
+      just go straight to http://matrix.org/alpha, specify a homeserver 
+      (defaults to matrix.org) and sign up and use it. (Sign-up security is
+      currently work-in-progress)
+    
+    - To run your own **private** homeserver on localhost:8080, install synapse 
+      with ``python setup.py develop --user`` and then run one with
+      ``python synapse/app/homeserver.py``
+      
+    - To run your own webclient:
+      ``cd webclient; python -m SimpleHTTPServer`` and hit http://localhost:8000
+      in your web browser (a recent Chrome, Safari or Firefox for now,
+      please...)
+       
+    - For now, register some accounts like ``@testing:localhost:8080`` from 
+      different browsers, join a room like ``#test:localhost:8080`` and have a 
+      play.
+      
+    - To quickly run a **public** homeserver that can exchange messages with 
+      other homeservers and participate in the overall Matrix federation, open 
+      up port 8080 and run ``python synapse/app/homeserver.py --host 
+      machine.my.domain.name``.  Then come join ``#matrix:matrix.org`` and
+      say hi! :)

+Identity Servers
+================
 
-Building Documentation
+The job of authenticating 3PIDs and tracking which 3PIDs are associated with a
+given matrix user 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. Meanwhile
+the job of publishing the end-to-end encryption public keys for Matrix users is
+also very security-sensitive for similar reasons.
+
+Therefore 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``, whose role is purely to authenticate and
+track 3PID logins and publish end-user public keys.
+
+It's currently early days for identity servers as Matrix is not yet using 3PIDs
+as the primary means of identity and E2E encryption is not complete. As such,
+we're not yet running an identity server in public.
