Editing Help:Template (section)

===Documentation===
{{Details|WP:Template documentation}}
Documentation for users, together with the template's categories, normally goes after the template code, inside {{tag|noinclude}} tags. It is normally necessary to put the opening {{tag|noinclude|o}} tag immediately after the end of the code, with no intervening spaces or newlines, to avoid transcluding unwanted whitespace.

In the case of complex templates, the documentation is often kept on a separate [[WP:Subpages|subpage]] of the template page (named "Template:{{var|XXX}}/doc"). This applies especially to many [[WP:Protection policy|protected]] templates, so that non-administrators can edit the documentation. To do this, place a call to the {{tlx|Documentation}} template after the main template code and within {{tag|noinclude}} tags. If the "/doc" subpage does not exist, a link appears when you display the template that you can use to create the subpage.

The documentation subpage, rather than the template itself, is normally what is placed in categories to represent a template.
