I am assuming that you have followed the schedules link above and that you are looking at a Cyclic Table for 14 Items.
All the message at the bottom means, is that if you want a schedule for 13 players, ignore match 1, and only play matches 2 to 7. As Player 1 always occurs in the first column, you will be left with a schedule for 13 players who are numbered 2 to 14.
One player in each round will get a bye, and you can read off who this is, as they are the person who is matched with player 1 in the unplayed match.
Hope that helps.
