+# Chat example
+
+
+## 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
+  * `some message` - just string, send message to all peers in same room
+  * client has to send heartbeat `Ping` messages, if server does not receive a heartbeat 
+  message for 10 seconds connection gets dropped
+  
+To start server use command: `cargo run --bin server`
+
+## Client
+
+Client connects to server. Reads input from stdin and sends to server.
+
+To run client use command: `cargo run --bin client`
