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

There are two files that you can change: Mediawiki:Copyrightwarning (edit page) and Mediawiki:Copyright (footer). Keep in mind you need to use HTML links here, not wikicode -- 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.
