This template just adds a heading above the SubPageList parser function call.
{{Messagebox You must pass an empty argument (the pipe character) in order to get the correct output due to a quirk with how template calls are given default arguments that would otherwise change the output of the parser function. }}
By transcluding this template with {{Subpages|}}, you get
{{#subpages:
page={{PAGENAME}}
|format=ul
|default="There are no subpages of the current page"}}
wherever you want to show a list of links to subpages.
The parser hook used comes from the mw:Extension:SubPageList extension, and the documentation gives further examples of customizing the output https://github.com/ProfessionalWiki/SubPageList/blob/master/doc/USAGE.md
Simple template to create a heading and invoke the #subpages parser function.
