When you say that you are new to this, do you mean to paper tuning, or new to the bow or archery in general?

If you are new to the bow or archery in general, this is what I would do, have a proshop set you up (or do it yourself if you can) at the correct centershot, both horizontally and vertically. Set the nock at about 1/4 - 3/8ths over 90 degrees. Get the correct arrows for the bow and shoot for a while. The tune should be fairly close to allow you to group pretty good. After you are grouping well, then do the final tuning.

The correct tuning can and will corelate with your shooting skills.
