Interesting but very simplistic.
3 strings (or courses) tuned to DAD, DGD, or CGC, usually with no's 2 & 3 being drones and 1 being melody. Frets are space diatonically so it plays a straight full note scale with no half-notes.
As they say in the tutorials and related books ..... just keep playing and you can't play a wrong note!
The other oft used description is 'a bagpipe with strings'.
