Templates

A template is a page you write once and reuse elsewhere. Include one by writing its name in double curly braces — {{Name}} — and its content is dropped in place. Templates can take parameters, so the same template can render differently on each page.

• Transclusion — including a template with {{ }}.
• Parameters — passing values in and using them.
• Include control — <noinclude>, <includeonly>, <onlyinclude>.
• Magic templates — built-in names like {{Note}} and {{Reflist}}.
• Namespaces — the wiki and template namespaces.
