I understood everything except point 6. - MAINTAIN the 5 degree tilt of the edges!

In the testimage, the lines are not horizontal and vertical. they are rotated by
5 degrees.
Now, if you setup your camera on the tripod, you could easily apply the
same 5 degrees to the camera so that the lines in the resulting image
would be vertical and horizontal ...
Point 6 says: Do NOT do this ... keep the camera horizontal, so that
the image taken withg the camera shows the same 5 degrees
rotation that was also on the testimage on the computerscreen.
