This category should contain only navbox templates (and, occasionally, less common template types) unless it is identified as an infobox or ambox category, or it contains a navbox subcategory named after itself (i.e. if this category were named "Name templates", its navbox subcategory would be "Name navbox templates"). If this navbox subcategory exists, place the topic's navboxes there.
To include a template in this category, add <noinclude>[[Template:Template category|{{PAGENAME}}]]</noinclude> to the end of the template code, making sure it starts on the same line as the last character of the code.
