On the Insert menu, click Page Numbers.
In the Position box, specify whether to print page numbers in the header at the top of the page or in the footer at the bottom of the page.
In the Alignment box, specify whether to align page numbers left, center, or right relative to the left and right margins, or inside or outside relative to the inside and outside edges of pages that will be bound.
If you don't want a number on the first page, clear the Show number on first page check box.
Select any other options you want.
