+
+## PP Websocket API
+The websocket server uses the WS library built into [combi-server](https://github.com/Commander-lol/combi-server) for
+standardised communications. The WS server expects JSON formatted into utf-8 text and will communicate back with such.
+Binary and slimmer string based versions of the protocols will be available when combi-server has been updated to 
+handle those.
+
+### Basic JSON format
+WS requests should contain two keys: a `type` key and a `payload` key; other data will be ignored. The value of the `type`
+key should be a string dictating the command being sent, while the value of `payload` should be a String, Number or JSON 
+object depending on what the server expects for the given type.
+
+If you're using ws.lib, as provided by combi-server, the `socket.message(type, payload)` method handles the formatting
+required, otherwise you'll need to manually create the command object.
+
+### PP Commands
+Currently the PP server listens for the following commands (`type` parameter) and expects the described data (`payload`):
+* _input_: A JSON object containing a `key` property that describes the key being input. This is a virtual key mapped to
+a gamepad, and not the actual keyboard key that might have caused the message to be sent or that might be pressed as a 
+result. Optionally contains an `auth` property with a Web Token hash.
+
+### PP Events
+Currently the PP server sends the following messages to clients (Listen to those that you want to handle):
+* _input-response_: Sent in response to an input. Payload will be undefined unless something was wrong with the request,
+safe to ignore in most cases
