-GratisDNS.dk (https://gratisdns.dk/) does not provide an API to update DNS records (other than IPv4 and IPv6
-dynamic DNS addresses).  The acme.sh plugin therefore retrieves and updates domain TXT records by logging
-into the GratisDNS website to read the HTML and posting updates as HTTP.  The plugin needs to know your
-userid and password for the GratisDNS website.
 
-```sh
-export GDNSDK_Username="..."
-export GDNSDK_Password="..."
-```
-The username and password will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

-```sh
-./acme.sh --issue --dns dns_gdnsdk --dnssleep 300 -d example.com -d *.example.com
