Use |from= and (or) |to= to describe the purpose of the redirects in the category.
The |template= parameter names the {{Redr}} template in redirect categories.
Use |parameters= to list the associated redirect template (rcat) used with the Redr template, along with its parameters.
Do not use the pipe symbol ( | ) to separate rcat parameters; use the {{!}} template instead.
Example
{{Redirect category|from=misspellings or [[typographical error]]s|to=the correct spellings|template=Redr|parameters=[[Template:R from misspelling|from misspelling]]}}
To add a redirect to this category, place {{Redr|from misspelling}} on the third line after the redirect. An alias/shortcut for the rcat(s) may also be used. "Redr" is an alias/shortcut for the This is a redirect template; for more information follow the template link. Neversubstitute redirect category templates nor place them on soft redirects.
These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).
This template should only be transcluded in the category namespace(s).
Shortcut
One shortcut can be installed within the lower maintenance banner, for example:
{{Redirect category|text=that target articles in which they are not mentioned|template=Redr|parameters=[[Template:R to article without mention|to article without mention]]|shortcut=CAT:RAW}}
which produces:
The pages in this category are redirects that target articles in which they are not mentioned.
To add a redirect to this category, place {{Redr|to article without mention}} on the third line after the redirect. An alias/shortcut for the rcat(s) may also be used.

If the template is transcluded on a page outside of the category namespace, then that page will not be added to these categories and will be added toCategory:Pages with templates in the wrong namespaceinstead.
