Shading Tutorial?

[Chazzanova]

Hi! I'm very interested in achieving a concise and accurate shading for a project. The problem is that I'm terrible at this point, so I would like to appeal to you.

Does anyone have a basic tutorial of shading? I would like to learn from CVS, but at this moment anyone is fine. I really need a foolproof's tutorial, because I'm new to this subject.

Anyway, thanks, and sorry for my bad english.

Not really a tutorial, but Rolento's site has some nice in-depth explanation of how things work (CVS,KOF, etc.) :
