+### Anleitung zum Benutzen
+Beim ersten Start des Programms wird die Datenbank erstellt und der erste Benutzer der angelegt wird, ist ein Mitarbeiter Account. Danach sind alle weiteren User für Eltern. Weitere Mitarbeiter können über das Mitarbeiter Menu erstellt werden.
+
+##### Desweitern werden Folgende Beispiel Accounts erstellt:
+Ein Eltern Account mit Kindern: 
+testparent@test.de/test
+
+Ein Mitarbeiter Account:
