The following template messages may be added to articles needing a cleanup. Their purposes are to foster improvement of the encyclopedia and to notify readers about possible problems. Unless otherwise noted, the cleanup messages, or tags, should be placed at the top—before other templates, images, or infoboxes, but after a possible hatnote (see WP:Hatnote#Placement). Certain tags can be placed at the top of an individual section, and others can be placed within the text itself (inline). Where the problem is not obvious, add an explanatory remark via the reason parameter as shown below or via the talk page.
