+# Stupides Wichtel Skript
+
+Zieht einen Wichtel für ein Liste von Leuten und sendet eine E-Mail an den
+Beschenker.
+
+# Usage
+
+Die Liste der Teilnehmer wird aus `./people.txt` eingelesen und erwartet folgendes Format pro Zeile.
+
+`<Name> <Email> <GroupId>`
+
+`GroupId` ist optional, falls angegeben wird nur unterschiedlichen GroupIds
+gezogen (z.B. Fred aus Familie A soll nur aus Familie B, C, ... ziehen können).
+
+Die Ziehung erfolgt per Zufall reihum. Falls für einen Teilnehmer kein Los
+mehr zu ziehen gibt, wird ein Fehler geworfen.
