+# BetterIServ
+BetterIServ ist ein Programm, welches semtliche Funktionen von IServ in ein Modernes Design verpackt.
+
+## Features
+- [x] E-Mails
+- [x] Datein
+- [x] Stundenplan
+- [x] Vertretungsplan
+- [ ] Aufgaben
+- [ ] Kalender
+
+## Self host
+Wärend es möglich ist, die docker images selbst zu hosten, gibt es noch keine Konfiguration. Somit müsste man in den Code der jeweiligen Dienste gehen und die domains und endpunkte manuell ändern.
+
+## Contribute
+Um am Projekt mitzuwirken, können sie entweder ein Issue erstellen und ein Feature anfragen oder ein Bug melden. Sofern sie selber den Code verbessern wollen, sind pull requests auch sehr gerne gesehen.
