How to set the yongnuo rf-603 up with my nikon d3100?

The instructions that came with it have been translated from chinese, but believe me, attempting to read chinese would be easier!

The best I could do was to find a link to a pdf file.

My best suggestion is to find someone mechanically inclined and work with them.
