These two help pages:
* Defining Different Headers and Footers 
* Alternating Page Styles on Odd and Even Pages
discuss how to organize alternating header/footer content on sequence of pages. The only way discussed there is using alternating page styles. However, there is an alternative suitable for simple cases, i.e. use of page style's "Same content on left and right pages" and "Same content on first page", available on Header and Footer tabs of respective style dialog.
These should be mentioned/linked, or discussed, on the said help pages, (1) to allow feature discoverability, and (b) for completeness.
