Help:Categories

For the editing guideline see Commons:Categories

Categories are used to arrange all the files and other pages in Wikimedia Commons into a hierarchical, interlinked structure. In mobile view, they are hidden unless ⧼mobile-frontend-mobile-option-amc/en⧽ is turned on in Special:MobileOptions (this option is only accessible in mobile view). They are at the bottom of virtually all pages and are sometimes linked elsewhere in a page.

An illustration of how the categories are linked.

The top of the hierarchy is Category:CommonsRoot.
