 5 **MksPaintable** - A GDK paintable object that receives rendering updates from QEMU, supporting both traditional framebuffer updates and DMA-BUF based updates for better performance.
 
 The library uses D-Bus communication with QEMU's display interface to:
+
 - Attach to VM screens and receive visual updates
 - Send keyboard/mouse/touch events to the VM
 - Configure screen properties                          
 - Handle clipboard sharing
 
 It's designed to work with QEMU's D-Bus display interface and provides a GTK-friendly API for integrating VM displays into GTK applications. The library supports both synchronous and asynchronous operations for all its functions.
+
 The project uses GTK 4, GIO, and various GTK components for the UI integration, with D-Bus for communication with QEMU.
