To contribute, the preferred way is to commit your changes on some publicly-available git repository (on a fork on github or on your own repository) and to notify the developers with either:
- a ticket on the bug tracker
- a pull request on github
- a simple message on the XMPP MUC
Even though Slixmpp’s github repository is just a read-only mirror, we can still be notified of the pull requests and fetch your mirror manually to integrate your changes.
