+# Professional RDP Client
+
+A modern Python-based RDP client with GUI interface that replaces the zenity-based bash script with enhanced functionality and better user experience.
+
+## Features
+
+- **Professional GUI Interface**: Modern tkinter-based interface with Microsoft RDP Client-like design
+- **Connection Management**: Save, load, and manage multiple RDP connections
+- **Credential Storage**: Encrypted password storage with automatic credential management
+- **Connection History**: Track and quickly access recently used connections
+- **Full Feature Support**: 
+  - Multiple monitor support
+  - Sound and microphone redirection
+  - Clipboard sharing
+  - Drive sharing
+  - Custom resolutions and color depths
+  - Various display options (wallpaper, themes, fonts)
+
+## Requirements
+
+- Python 3.6+
+- xfreerdp (FreeRDP client)
+- Required Python packages:
+  - tkinter (usually included with Python)
+  - cryptography
+  - threading
+  - subprocess
+
+## Installation
+
+1. Clone this repository:
+```bash
+git clone git@gitea.egonetix.de:root/rdp_client.git
+cd rdp_client
+```
+
+2. Install dependencies:
+```bash
+# Install FreeRDP
+sudo apt-get install freerdp2-x11  # Ubuntu/Debian
+# or
+sudo dnf install freerdp            # Fedora/RHEL
+
+# Install Python dependencies
+pip install cryptography
+```
+
+3. Make the script executable:
+```bash
+chmod +x rdp_client.py
+```
+
+## Usage
+
+### Running the Application
+
+```bash
+./rdp_client.py
+```
+
+Or with Python directly:
+```bash
+python3 rdp_client.py
+```
+
+### Virtual Environment Support
+
+The script automatically detects and uses a virtual environment if available in the same directory:
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install cryptography
+./rdp_client.py
+```
+
+### Creating Connections
+
+1. Click "New Connection" or press Ctrl+N
+2. Fill in the connection details:
+   - Server/IP address
+   - Username and password
+   - Domain (optional)
+   - Display settings
+   - Feature options
+3. Save the connection for future use
+
+### Managing Connections
+
+- **Connect**: Double-click a saved connection or select and click "Connect"
+- **Edit**: Right-click a connection and select "Edit"
+- **Delete**: Right-click a connection and select "Delete"
+- **Recent Connections**: Access recently used connections from the history list
+
+## Configuration
+
+Configuration files are stored in `~/.config/rdp-client/`:
+- `connections.json`: Saved connection profiles
+- `credentials.json`: Encrypted passwords
+- `history.json`: Connection history
+- `rdp_client.log`: Application logs
+
+## Security
+
+- Passwords are encrypted using Fernet (symmetric encryption)
+- Encryption key is derived from username@hostname
+- Credential files have restricted permissions (600)
+
+## Keyboard Shortcuts
+
+- **F1**: Show help and shortcuts
+- **Ctrl+N**: New connection
+- **Ctrl+Q**: Quit application
+- **Delete**: Delete selected connection
+- **Enter**: Connect to selected connection
+
+## Troubleshooting
+
+### Connection Issues
+
+1. Verify FreeRDP is installed: `which xfreerdp`
+2. Test manual connection with generated command (shown in logs)
+3. Check server accessibility: `ping your-server`
+4. Verify credentials and domain settings
+
+### Common Error Solutions
+
+- **STATUS_ACCOUNT_RESTRICTION**: Usually resolved by the built-in security parameter handling
+- **Connection timeout**: Check network connectivity and server availability
+- **Authentication failure**: Verify username, password, and domain
+
+### Logs
+
+Check the log file for detailed error information:
+```bash
+tail -f ~/.config/rdp-client/rdp_client.log
+```
+
+## Migration from Bash Script
+
+If migrating from the old zenity-based bash script:
+
+1. Connection profiles are compatible and will be automatically detected
+2. Encrypted credentials from the Python version will be used
+3. The bash script's .cred files (if any) need to be recreated in the new interface
+
+## Development
+
+### File Structure
+
+- `rdp_client.py`: Main application file
+- `README.md`: Documentation
+- `.venv/`: Virtual environment (if used)
+
+### Contributing
+
+1. Fork the repository
+2. Create a feature branch
+3. Make your changes
+4. Test thoroughly
+5. Submit a pull request
