This is a documentation subpage for Template:C0.
It contains usage information, categories and other content that is not part of the original template page.

This template adds a category if it is displayed in an article (namespace 0, "Main"). If it is used in a different namespace, for instance on a category or template page, no category is added.

It can be used within an infobox template that automatically categorizes articles to prevent the template itself from being categorized, or if an infobox is also used on other pages than articles.


{{c0|Category name}}

adds Category name to a page if it is in the article namespace.
