 | This is a documentation subpage for Template:Redirect category shell. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template is used on approximately 3,190,000 pages, or roughly 5% of all pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. Preview message: Transclusion count updated automatically (see documentation). |
 Important – please read! This template should not be used by a bot nor by any automated or semi-automated process without the use of parameters. It should not be used without parameters unless the redirect is manually categorized. This template may be used as a learning tool to assist editors who wish to learn how to categorize redirects. Only those editors who intend to return to the redirect to learn which rcats to use should apply this template without parameters, or with an empty first parameter. (more below) |
 | This template should not be substituted nor should this template and most redirect category (rcat) templates be used to tag soft redirects. Two exceptions are {{Soft redirect with Wikidata item}}, which can be used on all soft redirects, and {{R category with possibilities}}, which can only be used on soft redirects in the category namespace. |
This template is similar to {{WikiProject banner shell}} in that it may be used to add one or more appropriate redirect category (rcat) templates, along with their parameters, to redirects. Additionally, this template automatically senses, describes, categorizes and changes protection levels when appropriate. A third important function is to help editors learn more about redirect categorization by use of the manifold sort. For more information see the page below and the main rcat index.
