 When generating TouchGFX projects using CubeMX and the STM32CubeIDE application, it will clobber a bunch of settings in the project XML that require you to configure each time. Super annoying, and since ST/TouchGFX team can't get around to fixing this in a timely manner this patch was created.
 
 ## Usage
-It's a .NET Core application which you can run from the command line (Windows 10). After running the utility, you should be able to refresh your project (Right-click your project, choose Refresh) and build afterwards. Note that the utility will always create a backup of the project file when run - but as with all software you should rely on your own backups in case of the apocolypse.
