Addons for dummies

[Mirrikh]

This was probably asked many times before, and i most likely know the answer, but would anyone have kind of newbie guide to lua/addon creating. I know theres sites on learning lua and creating addons, but i feel its easier to learn it from someone firsthand instead of a "textbook" per-say. I guess for starters, i would focus on learning to create unitframes. Any and all advise/knowledge is welcomed.
