'''Transclusion''' is a general MediaWiki term for including things into a page using double-brace "<nowiki>{{}}</nowiki>" markup.
This includes [[Special:MyLanguage/Help:Templates|templates]], pages in other namespaces, [[Special:MyLanguage/Help:Magic words|magic words]], output of [[Special:MyLanguage/Help:Parser function|parser functions]], some [[Special:MyLanguage/Help:Special pages|Special pages]], [[Special:MyLanguage/Manual:Interwiki|interwiki pages]], and more.

==Target page syntax==

===Basic use===

To transclude a page, include both the namespace and the page name (separated with a colon) within the double-brace:

<pre><nowiki>{{Help:Transclusion}}</nowiki></pre>

When transcluding a '''[[Special:MyLanguage/Help:Templates|template]]''', you may omit the namespace and colon:

<pre><nowiki>{{infobox}}</nowiki></pre>

When transcluding an article in the '''Main namespace''', you may omit the namespace:

<pre><nowiki>{{:Transclusion}}</nowiki></pre>

When transcluding a '''subpage''' of the target page, you may use the subpage name by itself:

<pre><nowiki>{{/doc}}</nowiki></pre>

===Parameters===

Transcluded templates and {{ll|special pages}} may accept parameters:

<pre><nowiki>{{note|inline|This is a note.}}</nowiki></pre>

==Source page syntax==

Three tags ({{tag|[[#%3Cnoinclude%3E|noinclude]]|o}}, {{tag|[[#%3Cincludeonly%3E|includeonly]]|o}}, and {{tag|[[#%3Conlyinclude%3E|onlyinclude]]|o}}) control which content appears in the target page.

<dl>
<dt>{{anchor|&lt;noinclude&gt;|.3Cnoinclude.3E}} {{tag|noinclude|o}}</dt>
<dd>
Content within the {{tag|noinclude}} tags is excluded from transclusion on the target page. This content still appears on the source page.

</dd>

<dt>{{anchor|&lt;includeonly&gt;|.3Cincludeonly.3E}} {{tag|includeonly|o}}</dt>
