 # vKVM GUI
-
+The GUI is based on the FLTK (Fast Light Toolkit) and creates a window,
+which processes incoming signals from the Shared Memory into an visual image.
+The image refreshes on each change within the Shared Memory and periodically by itself.
 ## Installation
 
 Use the installation script provided in the Scripts repository
