+# Raspberry Pi Deployment Guide
+
+## Prerequisites
+- Raspberry Pi 4 (recommended) or 3B+
+- Raspbian OS (latest)
+- Python 3.7+
+- nginx (optional, for production)
+
+## Quick Start
+
+1. **Clone the repository**
+   ```bash
+   git clone <repository-url> /home/pi/myp-platform
+   cd /home/pi/myp-platform
+   ```
+
+2. **Install dependencies**
+   ```bash
+   sudo apt-get update
+   sudo apt-get install python3-pip python3-venv nginx
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+3. **Run deployment script**
+   ```bash
+   python deploy_raspberry_pi.py
+   ```
+
+4. **Start the application**
+   ```bash
+   python run_optimized.py
+   ```
+
+## Production Deployment
+
+1. **Install as systemd service**
+   ```bash
+   sudo cp myp-platform.service /etc/systemd/system/
+   sudo systemctl daemon-reload
+   sudo systemctl enable myp-platform
+   sudo systemctl start myp-platform
+   ```
+
+2. **Configure nginx (optional)**
+   ```bash
+   sudo cp nginx-myp-platform.conf /etc/nginx/sites-available/myp-platform
+   sudo ln -s /etc/nginx/sites-available/myp-platform /etc/nginx/sites-enabled/
+   sudo nginx -t
+   sudo systemctl reload nginx
+   ```
+
+## Performance Tips
+
+1. **Use a fast SD card** (Class 10 or better)
+2. **Enable swap** if you have less than 4GB RAM
+3. **Use nginx** for serving static files
+4. **Monitor temperature** and use cooling if needed
+5. **Disable unnecessary services** to free up resources
+
+## Monitoring
+
+Check application status:
+```bash
+sudo systemctl status myp-platform
+```
+
+View logs:
+```bash
+sudo journalctl -u myp-platform -f
+```
+
+## Troubleshooting
+
+- If the app doesn't start, check logs with `journalctl`
+- Ensure all Python dependencies are installed
+- Check that port 5000 is not in use
+- Verify file permissions in the app directory
