'''[[Help:Template|Templates]]''' are segments of wiki markup that are meant to be copied automatically ("transcluded") into a page.
You add them by putting the template's name in <nowiki>{{double braces}}</nowiki>. It is also possible to transclude other pages by using <nowiki>{{:colon and double braces}}</nowiki>.

There are three pairs of [[html element|tags]] that can be used in [[wikitext]] to control how transclusion affects parts of a template or article.
They determine whether or not wikitext renders, either in its own article, which we will call "'''here'''", or in another article where it is transcluded, which we will call "'''there'''".
* '''<nowiki><noinclude></nowiki>: ''' the content '''will not be rendered ''there'''''. These tags have no effect ''here''.
* '''<nowiki><includeonly></nowiki>: ''' the content  '''will render only ''there''''', and  '''will not render ''here''''' (like [[invisible ink]] made visible by means of transclusion).
* '''<nowiki><onlyinclude></nowiki>: ''' the content '''will render ''here''''' and '''will render ''there''''', but it will only render ''there'' what is between these tags.
There can be several such section "[[HTML#Elements|elements]]". Also, they can be nested. All possible renderings are achievable. For example, to render ''there'' one or more sections of the page ''here'' use '''<nowiki><onlyinclude></nowiki>''' tags. To append text ''there'', wrap the addition in '''<nowiki><includeonly></nowiki>''' tags before, within, or after the section. To omit portions of the section, nest '''<nowiki><noinclude></nowiki>''' tags within it.

If a page is transcluded without transclusion markup, it may cause an unintentional [[Help:Category#Putting_pages_in_categories|categorization]]. Any page transcluding it will contain the same category as the original page. Wrap the category markup with '''<nowiki><noinclude></nowiki>''' tags to prevent incorrect categorization.

Some templates take ''parameters'', as well, which you separate with the pipe character <code>|</code>.
