- [ ] Archive the corresponding [[https://www.wikidata.org/wiki/Q26719041|Wikidata item]] (change English description to `archived MediaWiki extension`, remove all statements, except `instance of (P31)`:`MediaWiki extension (Q6805426)` which should be altered to `Deprecated rank`, however if there's possible replacements, add `replaced by (P1366)` to those replacements)
- [ ] Remove submodule from `mediawiki/extensions.git`.
- [ ] Remove Jenkins pipeline from `zuul/layout.yaml` file in `integration/config.git`.

- [ ] [[https://phabricator.wikimedia.org/project/edit/1949/|Edit]] Phabricator project description, and add link to this ticket.
- [ ] [[https://gerrit.wikimedia.org/r/#/admin/projects/mediawiki/extensions/GlobalContribs|Mark]] the repository read-only in Gerrit, and prefix description with `[ARCHIVED] `.
- [ ] Archive the repo mirror in Phabricator Diffusion.
- [ ] Delete the repo mirror on GitHub.com.
