NIKON CLS system

While I was looking for information about the NIKON CLS system I came across this website:

NIKONCLS.COM

Looks like a very easy explanation of the NIKON CLS system with a step by step procedure and screen shots of how to set your Nikon speedlight in master or slave mode.

AMAZON has a nice book about the NIKON CLS too;
