From Freephile Wiki
This article is about creating a tabbed user interface in a MediaWiki installation.
Single Page

Another method involves connecting multiple pages together into a wizard or tutorial with a tabbed navigation. An example of this latter technique is the series of pages at https://en.wikipedia.org/wiki/Wikipedia:Tutorial
The interface for this technique involves using the page tabs template and the result looks like this:
Introduction | Page 2 | Page 3 | Wrap-up |
