Try the information on the A&H archery website (acsbows.com). Toward the bottom of the menu on the home page there is a link called "Knowledge base" that has a good breakdown on setting up and tuning a bow including bare shaft tuning.
It's a very simple process once you get used to it but it can be a little confusing at first. It's basically a process of shooting two or three bare shafts along with two or three identical fletched shafts and tuning until the bare shafts and fletched group together (point weight, shaft length, nock point...ect.). Start close and move back as your tune improves. The further back you go the better but I've found once my bare shafts and fletched are grouping together at 25 yards or so that's usually good enough. At that point you should be able to swap field points for same weight broadheads, confirm, and be set.
