I have a black nylon USGI silent sling, 50 inches long, 1.25 inches wide, with metal buckles, as seen below.

At the risk of sounding like a moron (a risk I'm prepared to take to get it done right), what is the proper way to install the sling? I'm talking in terms of attaching it to the two mounts, and threading it through the metal buckles. I'd prefer to get it right the first time.
Thanks!
