Line 10: − Your SME Server must be setup correctly with a FQDN and correctly setup DNS with your ISP. Your SME Server must also be connected to the internet, for the below procedure will interact with Letsencrypt servers.

==Prerequisites==
The Letsencrypt client and server interact to confirm that the person requesting a certificate for a hostname actually controls that host. For this reason, there are some prerequisites for your configuration. For example, if you're trying to obtain a certificate for www.example.com, the following conditions must be met:
* www.example.com is a valid domain name--the domain has been registered, and DNS records are published for it.
* www.example.com resolves to your SME Server--published DNS records give the external IP address of your SME Server when queried for www.example.com.
* Your SME Server is connected to the Internet.
* Port 80 on your SME Server is open to the Internet--you aren't behind a firewall, or some ISP filtering, that would block it.
Letsencrypt will issue certificates that include multiple hostnames (for example, www.example.com, example.com, and mail.example.com), all of which would be part of the request. All of the conditions above must be true for all of the hostnames you want to include in the certificate.
Make sure you've got this all set up correctly before continuing.
