Curl example Recommended

Use the following curl command to set home.example.com to the external IP of the requesting client:

# curl -s -L "https://api.simply.com/ddns.php?apikey=APIKEY&domain=example.com&hostname=home"

You can set this command to run in a crontab, on a local machine, every 15 minutes or so.
