+# Websocket chat broker example
+
+This is a different implementation of the
+[websocket chat example](https://github.com/actix/examples/tree/master/websocket-chat)
+
+Differences:
+
+* Chat Server Actor is a System Service that runs in the same thread as the HttpServer/WS Listener.
+* The [actix-broker](https://github.com/Chris-Ricketts/actix-broker) crate is used to facilitate the sending of some messages between the Chat Session and Server Actors where the session does not require a response.
+* The Client is not required to send Ping messages. The Chat Server Actor auto-clears dead sessions.
+
+Possible Improvements:
+
+* Could the Chat Server Actor be simultaneously a System Service (accessible to the Chat Session via the System Registry) and also run in a seperate thread?
+
+## Server
+
+Chat server listens for incoming tcp connections. Server can access several types of message:
+
+* `/list` - list all available rooms
+* `/join name` - join room, if room does not exist, create new one
+* `/name name` - set session name
+* `some message` - just string, send message to all peers in same room
+
+To start server use command: `cargo run`
