Any one have any experience with the I Ching?

I understand about using it as a divination system but am seeking further sharpening of my abilities to properly discern what I'm getting out of it. I don't completely get the relations between yin and yan lines and how I can derive any meaning from where they fall.

I also don't know how to approach the book simply as a philosophical text.

Any one have any good links for interpreting results? I am looking through a google search right now.
