[[!meta robots="noindex, follow"]] ikiwiki supports placing pages in a directory hierarchy. For example, this page, [[SubPage]] has some related pages placed under it, like [[SubPage/LinkingRules]]. This is a useful way to add some order to your wiki rather than just having a great big directory full of pages. To add a SubPage, just make a subdirectory and put pages in it. For example, this page is SubPage.mdwn in this wiki's source, and there is also a SubPage subdirectory, which contains SubPage/LinkingRules.mdwn. Subpages can be nested as deeply as you'd like. Linking to and from a SubPage is explained in [[LinkingRules]].
