That’s exactly what I thought. I had expected F1 to help me get started, but that’s not what it’s doing. Example patches are cool! But a general help/documentation inside the software would be cool, too.
Once when making an internal tool for a client instead of just documenting everything by myself together with the other developers what I did instead was make the help system a kind of in software wiki so the users(designers) could also organically build up the documentation together with the programmers.
Of course in the case of gamma docs you would need to have some kind of moderation/approval for it to work in order to have good quality.
I do realise you probably have enough to work on already though :)
