I could only say that you would need to input your FTP host, username, and password.
I researched the system and can only figure that the "Publish" method is a means of FTP'ing your site's files to the server.
The following field may not be correct, but you should be able to apply this to the actual fields.
Host: ftp.yourdomain.tld (e.g. ftp.ducky.x10hosting.com)
Username: your cpanel username
Password: your cpanel password
This could be in no way helpful to you, as I've never used the software.
None the less, I hope I've helped some.
