+=== QUICK START ===
+
+Execute script guimain.py to start graphical application.
+This application can start floppy disk emulator and provides means to download/upload patterns and modify them.
+It is based on existing python scripts, which were slightly modified for better user experience in graphical application.
+
+=================

 These files are related to the Brother KH-930E knitting machine, and other similar models.
