The F1 help text helps in that direction, but only once you're in the
GUI.

I did limited testing this time, couldn't get what is in the help text
in the GUI, close but not exactly, I'm applying, since this doesn't
affects anything outside these scripts and I think that if some set of
instructions, which I encourage you to detail next time, are followed,
then the expected result looks promising.
