Simple as pie. The Lyman sight has 3 screws: one on top (elevation) and one on the side (windage), and a locking screw. The 2 adjustment screws are for moving the rear sight up/down and left/right, the locking screw locks the sight in place after sighting in.

When shooting the rifle, you sight the rifle by looking through the hole in the rear sight. First, get a good sight picture. When you raise the rifle and look through the rear peep, the tip of the front sight should be centered in the circle of the peep sight. Make sure you focus on the front sight, your target will be blurry but you can see it in the background. Fire a few shots to get a group. Using the screws on the rear sight, move the rear sight in the direction you want the group to move in order to hit your intended point of impact. If the group is too low, raise the rear sight. If too high, lower the rear sight. If too far left, move the rear sight to the right. Easy, right?

There are vernier lines on the sight that you use to judge how far you are moving the sight.
