Template:Editintro documentation
Exists to give editintros a documentation, categories and interwikis. With the usual noinclude formatting, the documentation and the categories would still appear on any page that you're editing, but this template avoids this. To get the template working, you need to specify the |page= parameter, which should contain the name of the template. This parameter must not be {{FULLPAGENAME}} as the parser function will then always be right and the documentation and the categories will also appear on the page with the editintros. The default of this template is to transclude {{documentation}}, this can be overridden by specifying the |1= parameter.
