Template:Documentation/doc

For templates, insert  at the end of the template, then save the page, this will place   and a comment advising editors where to place categories and interwiki links. For other types of pages, the documentation template should already be there.

Click "create" at the top of the page and the documentation page will be opened with some pre-formatting. This formatting can also be created by using  on the documentation page.

Documentation pages will automatically be added to Category:Documentation pages. Using doc without  will add the page to Category:Pages with templates requiring substitution.

Optional parameters
This parameters can either be added to the  template when creating the page, or added to the   template afterwards.

type
Sets the "type" of documentation this is, e.g. template, module, message, etc. This will be used as part of some messages the template might display, as well as categorisation.

The type is automatic based on the namespace, so it shouldn't generally need to be set.

page
The page where the documentation should be. This defaults to a subpage of the current page called "doc".

content
Allows documentation content to be specified directly, rather than on a separate sub-page. Useful for small page-specific sub-page templates, e.g. Explosion/table.

nodoc
If a template has no documentation and you don't know how to use it, add nodoc=1 to the documentation template on the documentation page. The documentation's background will become red to make it more noticeable, and the page will be added to a category depending on the type of page.
 * Category:Templates with no documentation
 * Category:Modules with no documentation
 * Category:Widgets with no documentation

This is automatically set if the documentation page doesn't exist or is empty, so this generally isn't necessary to set.

baddoc
Similar to nodoc, this is used to mark templates that do have documentation, but it isn't very good. This can mean it doesn't have enough examples, doesn't explain all the functions properly, or doesn't explain the point of the template properly. The documentation's background will become yellow to make it more noticeable, and the page will be added to a category depending on the type of page.
