+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, install synapse 
-      with ``python setup.py develop --user`` and then run one with
-      ``python synapse/app/homeserver.py`` - you will find a webclient running
-      at http://localhost:8008 (use a recent Chrome, Safari or Firefox for now,
-      please...)
+    - To run your own **private** homeserver on localhost:8008, install synapse with
+      ``python setup.py develop --user`` and then run ``./synctl start`` twice (once to
+      generate a config; once to actually run) - you will find a webclient running at
+      http://localhost:8008. Please use a recent Chrome, Safari or Firefox for now...
              
-    - To make the homeserver **public** and let it exchange messages with 
-      other homeservers and participate in the overall Matrix federation, open 
-      up port 8448 and run ``python synapse/app/homeserver.py --host 
-      machine.my.domain.name``.  Then come join ``#matrix:matrix.org`` and
-      say hi! :)
+    - 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! :)

+This document outlines the format for human-readable IDs within matrix.
+
+Overview
+--------
+UTF-8 is quickly becoming the standard character encoding set on the web. As
+such, Matrix requires that all strings MUST be encoded as UTF-8. However,
+using Unicode as the character set for human-readable IDs is troublesome. There
+are many different characters which appear identical to each other, but would
+identify different users. In addition, there are non-printable characters which
+cannot be rendered by the end-user. This opens up a security vulnerability with
+phishing/spoofing of IDs, commonly known as a homograph attack.
+
+Web browers encountered this problem when International Domain Names were
+introduced. A variety of checks were put in place in order to protect users. If
+an address failed the check, the raw punycode would be displayed to disambiguate
+the address. Similar checks are performed by home servers in Matrix. However, 
+Matrix does not use punycode representations, and so does not show raw punycode 
+on a failed check. Instead, home servers must outright reject these misleading 
+IDs.
+
+Types of human-readable IDs
+---------------------------
+There are two main human-readable IDs in question:
+
+- Room aliases
+- User IDs
+ 
+Room aliases look like ``#localpart:domain``. These aliases point to opaque
+non human-readable room IDs. These pointers can change, so there is already an
+issue present with the same ID pointing to a different destination at a later
+date.
+
+User IDs look like ``@localpart:domain``. These represent actual end-users, and
+unlike room aliases, there is no layer of indirection. This presents a much
+greater concern with homograph attacks. 
+
+Checks
+------
+- Similar to web browsers.
+- blacklisted chars (e.g. non-printable characters)
+- mix of language sets from 'preferred' language not allowed. 
+- Language sets from CLDR dataset.
+- Treated in segments (localpart, domain)
+- Additional restrictions for ease of processing IDs.
+   - Room alias localparts MUST NOT have ``#`` or ``:``.
+   - User ID localparts MUST NOT have ``@`` or ``:``.
+
+Rejecting
+---------
+- Home servers MUST reject room aliases which do not pass the check, both on 
+  GETs and PUTs.
+- Home servers MUST reject user ID localparts which do not pass the check, both
+  on creation and on events.
+- Any home server whose domain does not pass this check, MUST use their punycode
+  domain name instead of the IDN, to prevent other home servers rejecting you.
+- Error code is ``M_FAILED_HUMAN_ID_CHECK``. (generic enough for both failing 
+  due to homograph attacks, and failing due to including ``:`` s, etc)
+- Error message MAY go into further information about which characters were
+  rejected and why.
+- Error message SHOULD contain a ``failed_keys`` key which contains an array
+  of strings which represent the keys which failed the check e.g::
+  
+    failed_keys: [ user_id, room_alias ]
+  
+Other considerations
+--------------------
+- Basic security: Informational key on the event attached by HS to say "unsafe 
+  ID". Problem: clients can just ignore it, and since it will appear only very
+  rarely, easy to forget when implementing clients.
+- Moderate security: Requires client handshake. Forces clients to implement
+  a check, else they cannot communicate with the misleading ID. However, this is
+  extra overhead in both client implementations and round-trips.
+- High security: Outright rejection of the ID at the point of creation / 
+  receiving event. Point of creation rejection is preferable to avoid the ID
+  entering the system in the first place. However, malicious HSes can just allow
+  the ID. Hence, other home servers must reject them if they see them in events.
+  Client never sees the problem ID, provided the HS is correctly implemented.
+- High security decided; client doesn't need to worry about it, no additional
+  protocol complexity aside from rejection of an event.

+
+Glare
+-----
+This specification aims to address the problem of two users calling each other
+at roughly the same time and their invites crossing on the wire. It is a far
+better experience for the users if their calls are connected if it is clear
+that their intention is to set up a call with one another.
+
+In Matrix, calls are to rooms rather than users (even if those rooms may only
+contain one other user) so we consider calls which are to the same room.
+
+The rules for dealing with such a situation are as follows:
+
+ - If an invite to a room is received whilst the client is preparing to send an
+   invite to the same room, the client should cancel its outgoing call and
+   instead automatically accept the incoming call on behalf of the user.
+ - If an invite to a room is received after the client has sent an invite to the
+   same room and is waiting for a response, the client should perform a
+   lexicographical comparison of the call IDs of the two calls and use the
+   lesser of the two calls, aborting the greater. If the incoming call is the
+   lesser, the client should accept this call on behalf of the user.
+
+The call setup should appear seamless to the user as if they had simply placed
+a call and the other party had accepted. Thusly, any media stream that had been
+setup for use on a call should be transferred and used for the call that
+replaces it.

webclient/CAPTCHA_SETUP

@@ -0,0 +1,46 @@
+Captcha can be enabled for this web client / home server. This file explains how to do that.
+The captcha mechanism used is Google's ReCaptcha. This requires API keys from Google.
+
+Getting keys
+------------
+Requires a public/private key pair from:
+
+https://developers.google.com/recaptcha/
+
+
+Setting Private ReCaptcha Key
+-----------------------------
+The private key is a config option on the home server config. If it is not 
+visible, you can generate it via --generate-config. Set the following value:
+
+  recaptcha_private_key: YOUR_PRIVATE_KEY
+  
+In addition, you MUST enable captchas via:
+
+  enable_registration_captcha: true
+
+Setting Public ReCaptcha Key
+----------------------------
+The web client will look for the global variable webClientConfig for config 
+options. You should put your ReCaptcha public key there like so:
+
+webClientConfig = {
+    useCaptcha: true,
+    recaptcha_public_key: "YOUR_PUBLIC_KEY"
+}
+
+This should be put in webclient/config.js which is already .gitignored, rather 
+than in the web client source files. You MUST set useCaptcha to true else a
+ReCaptcha widget will not be generated.
+
+Configuring IP used for auth
+----------------------------
+The ReCaptcha API requires that the IP address of the user who solved the
+captcha is sent. If the client is connecting through a proxy or load balancer,
+it may be required to use the X-Forwarded-For (XFF) header instead of the origin
+IP address. This can be configured as an option on the home server like so:
+
+  captcha_ip_origin_is_x_forwarded: true
+
+
+

 Basic Usage
 -----------
 
-The Synapse web client needs to be hosted by a basic HTTP server.
-
-You can use the Python simple HTTP server::
+The web client should automatically run when running the home server. Alternatively, you can run
+it stand-alone:
 
     $ python -m SimpleHTTPServer
 
 Then, open this URL in a WEB browser::
