Including the contents of a template page on a different page (by surrounding the page name with double braces, i.e. "{{}}" and leaving out the "Template:" prefix) is called transclusion.
This allows the other page to be automatically updated whenever the template page is updated.

Category:
Help:
Portal:
User:
Wikipedia:
The only difference between transcluding these and templates is that you must include the prefix (followed by a colon) with the page's name inside the double braces.
Images also can be transcluded, but this is done using double square brackets instead of braces.
