Now that the WP25 Easter Egg extension has been branched for the beta cluster and production in T411408, the next step is to **enable** the extension so that it is visible on the beta cluster.
== Requirements ==
In `mediawiki-config`:
* Add `extension:WP25EasterEggs` to the `extension-list` file.
* Define a new MediaWiki global variable, `wmgUseWP25EasterEggs`, in `initialiseSettings.php` and set it to `false`.
* Use `$wmgUseWP25EasterEggs` in `CommonSettings.php` to conditionally load the extension and its configuration.
* In `InitialiseSettings-labs.php`, set `wmgUseWP25EasterEggs` to `true` so that the extension is enabled on the beta cluster.
An example of this process can be found in the VueTest extension change:
https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/884361
== Acceptance criteria ==
* [ ] The Easter Egg extension appears on `Special:Version` on the beta cluster.
* [ ] The community configuration for the extension is visible on the beta cluster.
