Choose a hostname. The hostname you choose forms part of your site address. If you are The Acme Company You could enter "acme". This gives you a site addresses like http://acme.ftpstream.com and an FTP hostname acme.ftpstream.com

If you need http://ftp.acme.com, you can add this later, once the setup completes, go to the site properties tab on the control panel and note your IP address. Then setup a host record in your domain pointing at this IP.

Enter a password for the FTP login admim. The admin login is special as it has access to the home folders for your customer logins.
