+       Kaidan is a user-friendly and modern chat app for every device. It uses
+       the open communication protocol XMPP (Jabber). Unlike other chat apps,
+       you are not dependent on one specific service provider.
+
+       Kaidan does not have all basic features yet and has still some
+       stability issues. Current features include audio messages, video
+       messages, and file sharing.
