use {{R from initialism}} for those abbreviations that are pronounced as letters, such as CIA and HIV;
use {{R from short name}} for the initials of a person's name or for any other length reduction that is not typically classed as an abbreviation.
When appropriate, protection levels are automatically sensed, described and categorized.
Template {{Redirect category shell}} may be used to add one or more rcat templates, along with their parameters and categories, to a redirect. For more information, see the documentation page below.

#REDIRECT[[(target article title)]]{{Rcat shell|{{R from abbreviation}}}}
Template {{Rcat shell}} is an alias for the Redirect category shell template, which may be used to add as many appropriate rcats as needed, usually from one to seven, along with their parameters, to a redirect. For more information see the documentation on its template page. This rcat may also tag a redirect individually:
#REDIRECT[[(target article title)]]{{R from abbreviation}}
Use this rcat to tag only mainspace redirects from abbreviations to their expanded forms. Please do not use this template to tag an initialism or acronym, which are special types of abbreviations consisting of [usually] capital letters, such as HIV and NATO. For those, instead use {{R from initialism}} for those sounded out as letters, like CIA and USSR; or {{R from acronym}} for those read as words, like UNESCO and NASA. Also, if the redirect is from the initials of a personal name, then use the {{R from short name}} rcat instead.

Printworthiness
Please do not alter the printworthy settings of this rcat without first notifying the Version 1.0 Editorial Team, who are responsible for any and all materials, including redirects, that go into a printed version of Wikipedia.
In main-article namespace, many abbreviation redirects to expanded forms are considered unprintworthy; however, there are many others that are printworthy, so there is no default sort for printworthiness. In 2003, efforts were begun to support the Wikimedia Foundation's goal of increasing access and availability of Wikipedia articles in printed versions. Some rcats automatically populate either Category:Printworthy redirects or Category:Unprintworthy redirects by default. Others, like this rcat, do not, and that means it is up to editors to choose which of those categories, Printworthy or Unprintworthy, is appropriate and should be populated. The rcats that are used separately to populate those categories are:
