Instructions are online and in the software. There is also an "FAQ" page on the website.

Basically you take a picture of your group, or scan it on a printer/scanner (which is what I do now, and probably more precise). Then you copy the group pic to your computer, open the software, import the group pic, and then it's just a matter of:

1. telling the s/w your hole size (.224, in my case)
2. showing the s/w a known distance on the pic, for reference (the 1-inch X-ring, in my case)
3. inputting the center of each shot (this part is imperfect and subject to user honesty)

It's really easy once you do it a couple times.

The software is free but if you like it the guy who made it will take a $12 payment, which I recommend.

Thanks buddy, I just downloaded it, now for me to get some shooting in so I can see how I'm doing.
