Subpages are a way to arrange content in a tree-like structure. If a wikilink to a page contains a forward slash character ("/") in the article title, the preceding part is considered the parent page title, while the part following the forward slash is considered the subpage title. For example, the link [[Parent/Sub]] would link to a subpage "Sub" of the parent page "Parent". A link starting with a forward slash (for example [[/Sub]] will link to a subpage of the page the link is located on.
