Skin:MonoBook

MonoBook is a skin. It was the previous default man-skins>Special:MyLanguage/Manual:Skins|skin for wmf>Special:MyLanguage/Wikimedia Foundation|Wikimedia Foundation websites since mw-hist>MediaWiki 1.3|MediaWiki 1.3, as the replacement for the old usemod>Skin:Standard|Standard skin.

It became the most popular and most widely supported skin in the MediaWiki ecosystem until it was finally superseded by the vector>Special:MyLanguage/Skin:Vector|Vector skin as the default on May 13, 2010 (MediaWiki 1.17, ), as a result of the efforts of the wui>Special:MyLanguage/Wikipedia Usability Initiative|Wikipedia Usability Initiative to improve Wikipedia user experiences and potentially draw in more contributor participation.

It served as a common backup for Vector and is still present on many wikis using older versions of MediaWiki software.

Installation
This skin is included in the download>Special:MyLanguage/Download|MediaWiki download tarball.

You only need to install it separately if you installed MediaWiki using a different method.
