Contributing to Mainzelliste

We would love to include your useful changes to the Mainzelliste code in a future official release. In order to contribute code, we ask you to do the following:

  • Fork the repository (you probably have done so already if you read this).
  • Commit your changes to a branch different than master. If the commits already exist in the master branch, create a new branch from there. If possible, sign off the commits (see the notes on the developer certificate of origin below). Choose a meaningful name for the branch, preferably using a prefix like feature/ or bugfix/ to denote the type of changes.
  • Create a pull request from this branch to a new branch of the same name in our repository. We usually give short feedback on a pull request within a couple of days. The time it takes us to review the request will of course depend on the amount of code provided.

License compatibility

Every contribution must be under a license compatible to the GNU Affero General Public License, version 3 (AGPL), preferably the AGPL itself. See for a list of common software licenses and information about their compatibility to the AGPL. Please include a license header in every new file that is part of your contribution.
