Learning the triads was well worth the effort.
I reasoned that learning the notes on frets open through 22 would be helpful. Frets 1-12 may be easily broken down into six positions. I chose the Hal Leonard fake book, two volumes -- traditional hymns and country gospel. They are basically lead sheets -- chords, lyrics, and melody in handy CMajor, strong in Public Domain works. Band in a Box makes it easy to produce backing tracks. A digital recorder rounded out the setup.

F on the first fret string #1. Just as with any other band instrument, master one position at a time. Repeat at 12th fret. Follow along with vocal as appropriate. Takes time, but when finished, you have a set. I used NCH Crescendo to add and print out lead sheets in GMaj and Fmaj. I filled in some of the blanks with videos on

Really no different from steel guitar lessons I took in elementary school. it does take time, no way around that.
