+# DNS challenge Script für ipv64.net
+# Das Script soll genutzt werden um die DNS-01 Challenge per EXEC Methode über 
+# den "Let’s Encrypt client and ACME library written in Go" (LEGO) und die API von ipv64.net
+# LEGO Dokumentation: https://go-acme.github.io/lego/dns/exec/
+# API Dokumentation: https://ipv64.net/dyndns_updater_api.php
+# Mit dem Nginx Proxy Manager ist das Skript nicht kompatibel, da der NPM die EXEC Methode nicht unterstützt.
+# Daher wurde das Skript für die Nutzung mit Traefik umgesetzt.
+# Traefik Dokumentation: https://doc.traefik.io/traefik/https/acme/#providers
+# Getestet wurde es mit Traefik 2.9 aber auch 1.7 sollte es laut Dokumentation unterstützen:
+# https://doc.traefik.io/traefik/v1.7/configuration/acme/#provider
