+What is it?
+===========
+PHP WebSockets is a PHP library that implements the WebSockets protocol.
+The [WebSockets protocol](http://www.rfc-editor.org/rfc/rfc6455.txt) (RFC6455) is currently being
 standardized by the IETF. With WebSockets, a client (e.g.: a browser) and
 a server can set up a two-way communication channel with little overhead
-compared to a XMLHttpRequest or long polling.
-
-Usage
------
-The demo can be started by starting the `Demo/run.php` file from the command-
-line. You might need to edit the file to change the servers IP and/or port.
-
-The `ChatServer` demo is a basic chatserver that has little functionality. You
-can use it as a basis to build more complex `WebSocketServers` using this library.
-
-The basic idea is that your `WebSocketServer` should implement the `ServerObserver`
-interface and subscribe to (or observe) a `WebSocketServer` instance. If you want to
-observer or subscribe to events that accur on the incomming `WebSocketConnections` too,
-you should implement the `ConnectionObserver` interface too and subscribe to the
-incomming connections in the `ServerObserver :: onNewConnection()` method.
