Migrate to new API

README.md

 # Stud.FEED
 
+[Stud.FEED](https://git.finf.uni-hannover.de/kiste/studfeed) erstellt einen ATOM-Feed aus allen Veranstaltungen des aktuellen Semesters aus [Stud.IP](http://www.studip.de/) mittels
+der [REST-API](https://docs.studip.de/develop/Entwickler/RESTAPI).
+
+Damit das Skript auch hinter einem Webserver liegen kann, liegt eine FastCGI-Bridge bei.
