+# Jitsi Rooms
+
+Provides a small wrapper UI around Jitsi Meet with discord like rooms functionality.
+
+## Architecture
+
+The application consists of:
+
+- a plugin for the Jitsi Meet component prosody that pushes event data to a rest endpoint
+  - written in Lua
+  - location: ./prosody
+  - also provides a Jitsi Meet setup with docker
+- a backend that accepts the events with an rest endpoint and distributes it to the clients via websockets
+  - written in Haskell
+  - location: ./backend
+- a frontend that uses the Jitsi Meet iFrame Api and connects to the backend via websockets
+  - written in Typescript with react and vite
+  - location: ./frontend
+
+## Development
+
+Each subfolder contains a Readme with instructions
