+
+### Docker Setup
+- **Dockerfile** - Python 3.11 slim image, production optimized
+- **docker-compose.yml** - Two services: MariaDB + Flask app
+- **docker-entrypoint.sh** - Automatic DB initialization and health checks
+
+### Services
+1. **MariaDB** (mariadb:11.0)
+   - Port: 3306
+   - Persistent volume: `mariadb_data`
+   - Health checks enabled
+   
+2. **Flask App** (custom Python image)
+   - Port: 8080
+   - Volumes: code, logs, uploads, backups
+   - Depends on MariaDB
+   - Health checks enabled
+
+### Quick Deploy
+```bash
+./quick-deploy.sh
+```
+
+---
+
+## 📊 Database Schema
+
+### Tables (4 tables)
+1. **users** - User accounts (id, username, email, role, active status)
+2. **user_credentials** - Password hashes (separate for security)
+3. **quality_inspections** - Inspection records
+4. **application_settings** - App configuration
+
+### Features
+- Foreign key relationships
+- Timestamps (created_at, updated_at)
+- UTF8MB4 encoding for international support
+- Appropriate indexing
+
+---
+
+## 🔐 Security Features
+
+### Implemented
+- ✅ Secure password hashing (SHA256)
+- ✅ SQL injection prevention (parameterized queries)
+- ✅ CSRF protection (Flask default)
+- ✅ Secure session cookies (HTTPOnly)
+- ✅ Login required for protected routes
+- ✅ User role tracking
+- ✅ Connection pooling prevents exhaustion
+- ✅ Error messages don't expose system info
+
+### Production Considerations
+- Change default admin password immediately
+- Use strong SECRET_KEY
+- Enable HTTPS/TLS
+- Configure CORS if needed
+- Implement rate limiting
+- Add audit logging
+- Enable database encryption
+
+---
+
+## 📈 Scalability & Performance
+
+### Performance Features
+- Connection pooling (10 connections default)
+- Request/response compression ready
+- Static file caching via CDN ready
+- Rotating file logging

+2. Multiple app instances
+3. Shared database
+4. Redis caching (future)
+5. Elasticsearch (future)
+
+---
+
