Template:TemplatePAGENAME/doc

This is the documentation page for Template:TemplatePAGENAME.
This page is not intended to be viewed directly. Links using variables may appear broken; do not replace these with hardcoded page names or URLs.

{{TemplatePAGENAME/doc}} inserts the name of the template currently being documented. It is equivalent to either {{PAGENAME}} or {{BASEPAGENAME}} depending on whether the currently viewed page is the documentation subpage or the template itself (which presumably transcludes the documentation subpage via {{template doc}}).
