Transclusion is a general MediaWiki term for including things into a page using double-brace "{{}}" markup. This includes templates, pages in other namespaces, magic words, output of parser functions, some Special pages, 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:

{{Help:Transclusion}}

When transcluding a template, you may omit the namespace and colon:

{{infobox}}

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

{{:Transclusion}}

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

{{/doc}}

Parameters

Transcluded templates and Special pages may accept parameters:

{{note|inline|This is a note.}}

Source page syntax

Three tags (‎<noinclude>, ‎<includeonly>, and ‎<onlyinclude>) control which content appears in the target page.

‎<noinclude>

Content within the ‎<noinclude>...‎</noinclude> tags is excluded from transclusion on the target page. This content still appears on the source page.

Source page wikitext	What appears on the source page	What appears on the target page
Hello <noinclude>world</noinclude>	Hello world	Hello

‎<includeonly>

Content within the ‎<includeonly>...‎</includeonly> tags is transcluded on the target page, but does not appear on the source page. Other content is also transcluded.

Source page wikitext	What appears on the source page	What appears on the target page
Hello <includeonly>world</includeonly>	Hello	Hello world

‎<onlyinclude>

Content within the ‎<onlyinclude>...‎</onlyinclude> tags is transcluded on the target page, and also appears on the source page. Other content is not transcluded.

Source page wikitext	What appears on the source page	What appears on the target page
Hello <onlyinclude>world</onlyinclude>	Hello world	world
