+# RDP Client - Python Version
+

+- Timestamped export files
+
+### 🧪 **Connection Testing**
+- Test server reachability before connecting
+- RDP service availability checking
+- Detailed test results with troubleshooting hints
+- Network connectivity validation
+
+### ⌨️ **Keyboard Shortcuts**
+- **Ctrl+N** - Create new connection
+- **Ctrl+O** - Import connections
+- **Ctrl+S** - Export connections
+- **Ctrl+T** - Test selected connection
+- **F5** - Refresh connections list
+- **Enter** - Connect to selected connection
+- **Delete** - Delete selected connection
+- **F2** - Edit selected connection
+- **F1** - Show help dialog
+- **Tab/Shift+Tab** - Navigate between connection lists
+
+### 🔧 **Advanced RDP Features**
+- Full resolution control (including full screen)
+- Multiple monitor support (extend/span)
+- Audio redirection (local/remote/off)
+- Microphone redirection
+- Clipboard sharing
+- Drive sharing (home directory)
+- Printer redirection
+- USB device redirection
+- COM port redirection
+- Performance optimizations (compression, wallpaper, themes, fonts)
+
+### 📝 **Comprehensive Logging**
+- Detailed connection logs
+- Error tracking and diagnosis
+- User action logging
+- Automatic log rotation
+
+### 🚨 **Enhanced Error Handling**
+- User-friendly error messages
+- Detailed troubleshooting information
+- Network connectivity validation
+- RDP-specific error interpretation
+- Connection timeout handling
+
+## Installation
+
+### Prerequisites
+- Python 3.8 or higher
+- `xfreerdp` (FreeRDP client)
+- tkinter (usually included with Python)
+
+### Install FreeRDP
+```bash
+# Ubuntu/Debian
+sudo apt install freerdp2-x11
+
+# Fedora/RHEL
+sudo dnf install freerdp
+
+# Arch Linux
+sudo pacman -S freerdp
+```
+
+### Install Python Dependencies
+The script will automatically create a virtual environment and install dependencies:
+
+```bash
+# The cryptography package is automatically installed when first run
+pip install cryptography  # or let the script handle it
+```
+
+## Usage
+
+### Quick Start
+```bash
+# Make executable and run
+chmod +x rdp_client.sh
+./rdp_client.sh
+```
+
+### Direct Python Execution
+```bash
+# Using the virtual environment
+.venv/bin/python rdp_client.py
+
+# Or if you have dependencies installed globally
+python3 rdp_client.py
+```
+
+### Creating Your First Connection
+1. Click "New Connection" or press **Ctrl+N**
+2. Fill in the connection details:
+   - **Connection Name**: A friendly name for this connection
+   - **Server/IP**: The RDP server address
+   - **Username**: Your username
+   - **Password**: Your password (encrypted and stored securely)
+   - **Domain**: Optional domain name
+3. Configure advanced settings in the tabs:
+   - **Advanced**: Resolution, monitors, audio, clipboard, drive sharing
+   - **Performance**: Compression, visual effects, hardware redirection
+4. Click "Save" to store the connection
+
+### Connecting
+- **Double-click** any connection to connect immediately
+- **Select** and click "Connect" 
+- **Select** and press **Enter**
+- Use **Recent Connections** for quick access to frequently used servers
+
+### Testing Connections
+- Select a connection and click "Test Connection" or press **Ctrl+T**
+- The test will verify:
+  - Network reachability
+  - RDP service availability
+  - Port accessibility
+- Detailed results help troubleshoot connection issues
+
+## File Locations
+
+All configuration files are stored in `~/.config/rdp-client/`:
+
+- `connections.json` - Saved connection profiles
+- `credentials.json` - Encrypted credentials
+- `history.json` - Connection history
+- `rdp_client.log` - Application logs
+
+## Migration from rdp.sh
+
+The Python version can coexist with the original `rdp.sh` script. While they use different storage formats, you can:
+
+1. Export connections from the old script (if supported)
+2. Manually recreate important connections in the new GUI
+3. Use the import functionality to bulk-add connections
+
+## Security Notes
+
+- Passwords are encrypted using Fernet (AES 128) with PBKDF2 key derivation
+- Encryption key is derived from username@hostname combination
+- Credentials are only decryptable by the same user on the same machine
+- Log files do not contain passwords (shown as ***)
+- Export files can optionally include encrypted credentials
+
+## Troubleshooting
+
+### Common Issues
+
+**"xfreerdp not found"**
+- Install FreeRDP: `sudo apt install freerdp2-x11`
+
+**"Connection failed - Authentication error"**
+- Verify username, password, and domain
+- Check if account is locked or disabled
+- Use "Test Connection" to verify server accessibility
+
+**"Server unreachable"**
+- Check server address and network connectivity
+- Verify firewall settings
+- Ensure RDP is enabled on the target server
+
+**"GUI doesn't start"**
+- Ensure tkinter is installed: `sudo apt install python3-tk`
+- Check Python version: `python3 --version` (3.8+ required)
+
+### Logs and Debugging
+
+Check the log file for detailed error information:
+```bash
+tail -f ~/.config/rdp-client/rdp_client.log
+```
+
+## Contributing
+
+The RDP client is designed to be modular and extensible. Key areas for enhancement:
+
+- Additional RDP client backends (rdesktop, xrdp)
+- LDAP/Active Directory integration
+- Connection profiles with templates
+- Multi-language support
+- Plugin system for custom authentication
+
+## License
+
+This project follows the same license as the original rdp.sh script.
+
+## Version History
+
+- **v2.0** - Complete Python rewrite with GUI
+- **v1.x** - Original bash/zenity implementation
+
