Phabricator/Migration Timeline

We are working on the migration of several developer infrastructure services to one single Phabricator instance.

It's a very exciting project! We welcome your help.


 * Git and Gerrit users are welcome to the Gerrit-Migration project. We need help learning about the possibilities of Phabricator in this area: what is missing, what exists in a different way, what is remarkably interesting, which are the blockers that should be reported upstream?


 * As a PHP developer, you're welcome to contribute enhancements and new features upstream. Learn more at .

Beware, the [https://phabricator.wikimedia.org/tag/phabricator/ Phabricator team] may change this sequence as plans evolve (although we try not to).
