MediaWiki User Guide/Hyperlinks

There are two types of hyperlinks in MediaWiki: internal, also called wikilinks, and external.

Redirecting
Readers and editors from different backgrounds search for the same topic under different titles, such as TODO. To avoid replication of similar content and confusion of editors and readers, the editors of a wiki website usually choose one topic title as the authorized one, under which the content is to be created, and let one or more alternative topic titles redirect to it.

To let a page title redirect to another one, create a page with the unauthorized (or minor) title, containing only the following text:


 * 1) REDIRECT Authorized topic title

An alternative markup; notice the additional colon (":"):


 * 1) REDIRECT: Authorized topic title

If an unauthorized topic title has more possible target authorized topic titles, redirecting does not do. In that case, a disambiguation page can be created, such as:

The exact wording depends on the kind of content of the wiki website.
