There was a website even with pictures how to do it, but I can't find it anymore. So I'll do my best to describe it to you, it's simple enough anyway. You position your camera to focus with the AF point on the focus target which is right next to the angled ruler. So not the center of the LensCal board, but closer to the right edge. Best to have the camera on a tripod. Then look thru your viewfinder and observe how the angled ruler lines up against the right vertical edge of the LensCal board. If thing are misaligned, there may be a gap at the top between the board and the ruler and it may overlap at the bottom, or vice versa. Since the ruler top and bottom may be out of focus, it often helps to stop down and press the DOF preview button to have it all nicely in focus. When things line up, the left edge of the ruler should be parallel and pretty much form one line with the right edge of the focus target board.

When you use wide angle lenses and/or use longer focus distances, you will be using more of the LensCal focus target area, not just the small target on the right, but the principle will remain the same.

It is much easier in practice than it sounds, and at least I found it to be faster and more convenient than those red dots and holes to align with the LensAlign. A side benefit is that the angled ruler is right next to the focus point, so lens field curvature will have less of an impact. And any small misalignment between the camera back and the focus target that you may have left with either product will also result in less of an error with the LensCal than the LensAlign which forces you to focus on the center of the target.
