Clarification of hostname instructions

Hello,

In the installation instructions for CWP it says "This hostname cannot be the same as any domain that is on your server (for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname)." So it says it cannot be a domain on the server, but then gives an example of using a domain on the server. Should it instead read "can be any domain on your server"?

My situation is that I have a VPS that I will use to host just one website. Should the hostname then be a subdomain of the  domain name of the website I am hosting?

Thank you.

Yes, you can setup hostname as a subdomain (server.domainname.com) of the website you're hosting.
