-- Node.js (v14 or higher)
+- Python 3.11 (required - Python 3.13 has compatibility issues with some dependencies)
+- Node.js (v18 or higher)

+## Development
+
+### Running in Development Mode
+```bash
+# Ensure virtual environment is activated
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Run backend (will also serve frontend)
+python main.py
+```
+
+The application runs on port 3000 by default.
+
+### Troubleshooting
+
+If you encounter issues:
+
+1. **Python version issues**: Ensure you're using Python 3.11. Python 3.13 has compatibility issues with current SQLAlchemy versions.
+2. **Installing Python 3.11**:
+   - macOS: `brew install python@3.11`
+   - Ubuntu: `sudo apt install python3.11 python3.11-venv`
+   - Windows: Download from python.org
+3. **Module not found errors**: Make sure virtual environment is activated and dependencies are installed
+4. **Port already in use**: The app will try to use port 3000
+5. **Database issues**: Delete `database.sqlite` file and restart
+
 ## API Endpoints
 
 - `POST /api/auth/login` - User authentication
 - `POST /api/auth/register` - User registration
 - `POST /api/snippets` - Create/update snippets
 - `GET /api/snippets/:id` - Retrieve a specific snippet
 
-## Development
-
-Both backend and frontend run on port 8000:
-```bash
-python main.py
-```
