This template links to a page on mediawiki.org from the [[Help:Contents|Help pages]]. The template has two parameters:
# Pagename, optionally preceded by an interwiki link prefix valid on mediawiki.org
# (optional) Link description
<!-- Compatibility Note: The "mw" prefix is the only in the default interwiki prefixes since MediaWiki 1.16 (see mw:Manual:Interwiki#References). If you plan to use this script with an older version, it might be possible or necessary to you use the "mediawikiwiki" prefix. -->

| This is so that the public domain help pages - which can be freely copied and included in other sites - have correct links to Mediawiki:
* on external sites, it creates an interwiki link to 'mw' (included in the default interwiki table for new installs)
* on Mediawiki, it creates an internal or interwiki link

'''All''' links from the Help namespace to other parts of the mediawiki.org wiki should use this template.}}

== Demo of interwiki link ==

<nowiki>{{mediawiki|m:Help:Calculation|Help:Calculation}}</nowiki> gives either<br /> <nowiki>[[m:Help:Calculation|Help:Calculation]] or [[mw:m:Help:Calculation|Help:Calculation]]</nowiki>.
