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
)
