Teaching NL to someone who has never played poker before

[Yeti]

How would you go about this?

I once tried to teach it to my girlfriend and didn't have much success. Once you start talking you realise how much there is to say, and it's tons to take in.

My friend is keen to play to make some money. He is a very smart kid and I'm confident that with the right guidance he could tear through the limits.

Where to start though? Are there any good books that could do the majority of the ground work for me?

Is it worth giving him a very basic idea of limit first and then moving to NL? Do I start on full tables or 6-max?
