Template:Documentation subpage

This template displays a message that the current page is a documentation subpage.

Display
This template should normally be placed at the top of /doc pages. It changes output depending on where it is viewed:
 * On a /doc page, it displays a box explaining template documentation and links to the template page.
 * On other pages – i.e. pages transcluding the /doc page – the template will not show. The template page itself (which contains ) will automatically note that the documentation is transcluded from a subpage.

Functions
In addition to its message, the template adds pages to Category:Template documentation pages, Category:User documentation pages, or similar (named after the subject space), but only for documentation pages in namespaces with the subpage feature. It defaults the sort key to the page name without namespace: Template:Foo, for example, would be sorted as "Foo", i.e. under "F".
