Template:Container category/doc

Usage
Tag categories with  to inform editors that they should not contain anything other than subcategories.

The categories will be added to Category:Container categories. If the template is transcluded on a page outside of the category namespace, the page will not be added to Category:Container categories.

Do not substitute this template.

Categories that are part of Wikipedia administration should be tagged with Wikipedia category instead.

Placing right-aligned content beside the template
Use  to place right-aligned content – such as portal (to provide a link or links to related portal or portals) and/or Commons category (to provide a link to the same or a similarly-named category at the Commons) – beside the template. If more than one box is included, ensure the widest one appears first, otherwise overlapping may occur.
