+Information
+===========
+
 This is Version 2, a complete rewrite of MyOwnNotes. This application does not depend on the server side owncloud notes app anymore. However, it does depend on the `ownCloud android application`_ for authentication.
 
 MyOwnNotes 2 has not been released on the official android store yet. Release will follow in the next couple of weeks. Feel free to add issues after consulting the CONTRIBUTING.rst file.
