 TL;DR - If you need to build an application with neatly wrapped classes without caring to much about the internals, go with Ratchet. If you want to work with websockets in the same way you work with sockets in ReactPHP, go with this library.
 
+## Missing Features
+
+The following features are missing, or work in progress:
+
+* Idle timeout and ping timeout
+* Protocol errors should close with error codes
+* Exceptions
+
 ## Server
 
 The WebSocket handler is built as a HttpServer middleware. This makes sense as WebSocket as a protocol is running over HTTP. Connections are set up by the middleware and exposed via the `connect` event.

+## Sending messages
+
+You can use the `ConnectionGoup::writeAll(string $payload)` method to send the payload to all members of the group.
+
+## Disconnecting clients
+
+You can disconnect clients cleanly on shutdown by using the `GroupManager::closeAll(string $reason, int $code)` method. You can also call on `ConnectionGrroup::closeAll` manually do disconnect a whole group.
+
 ## Future
 
 * Add a GroupManagerImplementation so custom logic can be provided.
