13.3 - Provide information about the general layout of a site (e.g., a site map, or table of contents).

A textual site map (or table of contents) like the one below is a good bet because it is relatively easy to maintain (and doesn't require an accessible alternative as would a graphical map). Note that the linked text should correspond to the main page title or H1 header on the target page so that the user isn't confused by seeing different titles.
