+-----------------------
+
+Development platform
+~~~~~~~~~~~~~~~~~~~~
+
+Main development of AlekSIS is done on the `EduGit`_ platform in the
+`AlekSIS group`_ and discussions are held on the linked `Mattermost team`_.
+
+All platforms and tools mandated for development are free software and
+freely usable. EduGit accepts a variety of sources for login, so
+contributors are free to decide where they want to register in order to
+participate.
+
+If any contributor cannot use the platforms for whatever reasons, patches and
+questions directed at the developers can also be e-mailed to
+<aleksis-dev@lists.teckids.org>.
