-### Backend
+   ```bash
+   ./build.sh --switch --[local|testing|staging|production]
+   ```
 
-Go inside virtual environment:
+3. Build the APK:
 
-`source ./venv/bin/activate`
+   ```bash
+   # For debug build
+   ./build.sh --build --[local|testing|staging|production] --debug
 
-Start UWSGI backend:
+   # For release build
+   ./build.sh --build --[local|testing|staging|production] --release
+   ```
 
-```bash
-uwsgi --http :5000 --gevent 1000 --http-websockets --master --wsgi-file __main__.py --callable app -s 0.0.0.0:3030
