 3) if a CNAME is set for "www.example.org", you can redirect there from the naked domain by adding an ALIAS record
 for "example.org" (if your provider allows ALIAS or similar records, otherwise use A/AAAA), together with a TXT
 record that points to your repo (just like the CNAME record):

 Certificates are generated, updated and cleaned up automatically via Let's Encrypt through a TLS challenge.
