 ### Things to know about the structure
 
-1. Everything depends on Redis (API and frontend).
-2. The proxy-container is optional (Caddy), but makes your life easier
-3. You need to set your reverse proxy up, so that it allows Socket.io-connections.
+Since this repo is a monorepo, the frontend is located in
+the [`frontend/`](https://github.com/mawoka-myblock/ClassQuiz/tree/master/frontend)-directory.
+The backend-project (Pipfile) is in the root, but all the code is located in
+the [`classquiz/`](https://github.com/mawoka-myblock/ClassQuiz/tree/master/frontend)-folder.
