Help:Revert a page
Wikimedia help page / From Wikipedia, the free encyclopedia
Reverting is changing a Wikipedia page back to an older version of the page. Because Wikipedia can be changed by anybody, the MediaWiki software is designed to save every version of a page when it has been changed by someone. When a new version of the page is saved, the old version is kept in the page's change history, so that anybody can see who changed the page, when they did it, and what changes they made to the page. You can change the page back to any of the old versions in the page history, such as when something has been added or removed when it should not have been.
