Template:Templatehelp

If you put

 <noinclude>{{Templatehelp}}</noinclude>

at the end of your template text the text of a like-named page in the Help: namespace.

For example the page Help:Voweltable will be included when you view the page Template:Voweltable but not when you actually use

{{Voweltable|parameters}}

in the body of another page.

If the help page has not yet been created there will appear a link to it instead of its not-yet-existing content, just as with not-yet-created templates.

The idea of (no)including a help page in a template page is that users can see usage instructions for a template when viewing the template page, but at the same time they won't get the whole of the usage instructions included when they use {{subst:templatename}}, but only the single line

<noinclude>{{Templatehelp}}</noinclude>

which can then easily be removed. Make sure to put

<noinclude>{{Templatehelpnote}}</noinclude>

at the top of your help page! (Cf. Template:Templatehelpnote)
