I, too, got my start using the Paterek manual, although in paper form, not on disk. Found it to be the right amount of information to get my head wrapped around building a frame. Experiencing the build is the authoritative teacher, but Paterek manual is a good place to start provided you already have some very basic brazing experience at some point in your life. It was 30 years between brazing sessions when I built the first frame. Not until the 3rd frame did I feel comfortable getting good flow. Still don't trust myself with building a fork! Yes, a cautious one I am.
