-## Frontend
-
-Since the frontend is using [Vite.js](https://vitejs.dev/), all changes in this area will be hot-reloaded.
-You don't need to restart the frontend, unless you try to add a new frontend dependency.
-
-## Backend
-
-The backend does not automatically hot-reload.
-You will need to restart the backend after changing something using these steps:
-
-1. Click `Terminal`
-2. Click `Codespaces: server-dev` in the right panel
-3. Press `Ctrl + C` to stop the server
-4. Press `Up` to run `npm run start-server-dev`
