+
+## System Requirements
+
+- Python 3.7+
+- Flask web framework

+- Linux environment (Raspberry Pi OS recommended)
+- Network connectivity for device communication
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone https://gitea.moto-adv.com/ske087/Server_Monitorizare.git
+cd Server_Monitorizare
+```
+
+2. Install dependencies:
+```bash
+pip3 install flask requests sqlite3
+```
+
+3. Set up the database:
+```bash
+python3 Working_Files/initalizedb.py
+```
+
+4. Configure port capabilities (for port 80):
+```bash
+sudo setcap 'cap_net_bind_service=+ep' $(which python3)
+```
+
+5. Start the server:
+```bash
+python3 server.py
+```
+
+## Configuration
+
+### Device Communication
+The server communicates with devices on **port 80**. Ensure your devices are configured to run on this port.
+
+### Database Setup
+The system uses SQLite database located at `data/database.db`. The database is automatically created on first run.
+
+## API Endpoints
+
+### Device Logging
+- `POST /logs` - Submit device logs
+- `POST /log` - Alternative logging endpoint
+
+### Device Management
+- `GET /` - Main dashboard
+- `GET /devices` - Device management interface
+- `GET /device_logs/<hostname>` - Device-specific logs
+
+### Command Execution
+- `POST /execute_command` - Execute command on specific device
+- `GET /device_status/<ip>` - Get device status
+
+### Auto-Update
+- `POST /auto_update_devices` - Trigger auto-update on all devices
+- Database reset and management endpoints
+
+### Server Operations
+- `GET /server_logs` - Server operations logs
+- `POST /reset_database` - Reset database (with confirmation)

+
+## Security Features
+
+- Secure command execution with timeout protection
+- Database transaction safety
+- Input validation and sanitization
+- Error logging and monitoring
+
+## Device Integration
+
+This server works in conjunction with device applications running on Raspberry Pi devices. The devices should:
+
+1. Run the companion app on port 80
+2. Send logs to the server via POST requests
+3. Respond to remote commands and status requests
+4. Support auto-update functionality
+
+## Development
+
+### Adding New Features
+1. Create new routes in `server.py`
+2. Add corresponding HTML templates in `templates/`
+3. Update database schema if needed
+4. Test thoroughly before deployment
+
+### Database Schema
+The system uses a simple logging table with fields:
+- hostname, device_ip, nume_masa, timestamp, event_description
+
+## Troubleshooting
+
+### Common Issues
+1. **Port 80 Permission Denied**: Use `setcap` command as shown in installation
+2. **Database Locked**: Ensure no other processes are accessing the database
+3. **Device Communication Errors**: Check network connectivity and firewall settings
+
+### Logs Location
+- Server logs: Check terminal output or use `/server_logs` endpoint
+- Database logs: Stored in SQLite database, accessible via web interface
