This template is to be placed on every navigation template directly in front of the title in the template's header. It must be typed in the form of {{edit|NAME}}, where "NAME" is the name of the template (minus "Template:"). For example, on Template:MB, {{edit|MB}} would be used, and the coding at the top of the template would look like this:
{| class="mw-collapsible mw-collapsed navbox mario"
!colspan=2 style=background:#CC0000|{{edit|MB}}''[[Mario Bros. (game)|Mario Bros.]]''
