Sorry, just a dumb question: Did you have a look into the link I posted?
Honestly: it is called: "How To Apply Shaders", it is in German and in English, a step by step explanation, and now I read in your last reply: "I was hoping for a tutorial or something" - what do you want? That someone carries you on his hands? Or, would you try at least reading on your own? ;\) :P
