+# Certbot authentication hooks for knot DNS
+
+KnotDNS is my preferred authoritative DNS, so I wrote these quick scripts for certbot authentication.  
+There are two versions, one for when the DNS is being hosted at the same location as the certbot request, 
+and one for where we have to send a DNS update to the authoritative DNS server, such as when behind an 
+dynamic IP.
