Using a capo is easy. You just have to think of it as a movable nut. Clamp it on the fret you will use for the key you are playing in, and just play chords or picking from a key you know. You can play in G using chords from the key of F if you put the capo on the second fret.
Some instruments have 6 strings (often the first and third course doubled), or 8 strings (all courses doubled) - called the taropatch, see under. A ukulele always has nylon (or gut) strings, never steel. Playing is strumming with the fingers or with a pick, to accompany singing or Hawaiian dance music.
