+Mattermost
+*************
+The faculty for computer science hosts a `mattermost instance <https://mm.cs.ovgu.de>`_ to which you can register and join an existing team.
+For that a team admin has to invite you to it.
+Team admins currently are: **Nico Marek**, **Peter Varvra** and **Manuela Kuhn**
+
+Every team has two types of channels:
+
+* public: everybody can join
+* private: one can only join after an invitation of a channel member
+
+By default every team has two public channels: "Off-Topic" and "Town Square".
+
+In addition one-to-one-communication between people is also possible via "direct message".
+
+A more detailed explanation on how to use mattermost can be found on `the official mattermost documentation <https://docs.mattermost.com/guides/user.html>`_.
