-This page details the process of sending information between the frontend (coach vr) and Unity. Communication occurs via web sockets in a (roughly) event-based manner (somewhat like Socket.IO, but due to lacking a correct server implementation on the Unity-side of things we're using bare web sockets instead).

-## Frontend (Coach VR)
 
+## Multiple Coaches
+We are working on a solution to give the possibility to connect more than one coach with Unity. This is a rough sketch. 
+
+For this, we use a new abstraction: rooms. Unity creates a new room when the participant enters a classroom. Coaches can join these within a one-to-many connection (multi-user).
+
+Management and message flow are done via a central web service with a Socket.io base and uses simple communication protocol. For this, we revised the integration and use it event-based via Scriptable Objects.
