What does it take to upgrade iBook G4 from 10.4.11 to Leopard or Snowleopard

I would like to upgrade my iBook G4 to Snow-leopard 10.6, what do I have to do or buy or install first, I'm not a computer-whiz, and electronics make me feel real dumb.
Some body please explain it in a simple language. Thanks :-))
