Can you be a bit more specific in your question, please? Are you looking for a beginner's guide to biblatex? (In that case https://tex.stackexchange.com/questions/13509/ would be a good place to start.) Or are you looking for an introduction into LaTeX in general? (Then you may want to start with https://tex.stackexchange.com/questions/11.)
