Translations:Help:Changing your wiki license/25/en

There are three files that you can change: Mediawiki:Copyrightwarning (edit page), MediaWiki:Copyright, and MediaWiki:Mobile-frontend-copyright (footer). Keep in mind you need to use HTML links here, not wikicode—as you're editing system messages. This is in some ways the most dangerous option—make sure you know what you're doing legally. Linking to a more extensive Copyrights page is recommended.
