How to enable language navigation for content?

How can I enable the language links on my MedaiWiki install? The one I am talking about is the one that spans the bottom of the page and starts with [Language: English, French, etc...)

开发者_StackOverflowJust to be clear, it is the language navigation stuff directly under the download button on the homepage for MediaWiki.

That is not a feature built into MediaWiki, it is done with templates and parser functions. If you want something similar, you could copy their Template:Languages and related templates.
