Why do you put the first row of shingles upside down?

Do you overlap shingles side to side?
When you reach a peak or hip, shingle all the way up the first side (until the reveal portion of the shingles is within 4 inches of the peak) and cut the 3-tab shingles just below the ridge. Shingle the other side and allow these pieces to overlap the ridge by no more than 4 inches.07-Aug-2020
