#REDIRECT[[(target article title)]]{{Rcat shell|{{R from scientific abbreviation}}{{R printworthy}}}}
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 scientific abbreviation}}
This is in accord with instructions found at WP:REDCAT.
Use this rcat to tag all mainspace redirects from scientific abbreviations to their expanded forms. Please do not use this template for general acronyms or for other non-scientific abbreviations. Instead, use either {{R from acronym}} or {{R from initialism}}, whichever applies.
