 ## 🐛 Troubleshooting
 
 ### "No module named 'face_recognition'"
+The project ships its own local `src/face_recognition.py` module (no installation needed).
+If you see this error, make sure you are running the app from the repository root so that
+`src/` is on the Python path, or run via the provided entry points:
 ```bash
-pip install face-recognition
-# Note: First install takes 5-10 minutes
+python web_app.py        # web UI
+cd src && python main.py # CLI
 ```
