Looks like you got it from godaddy.com
1. Log into your godaddy cpanel.
2. get your ftp username and password.
if you're on windows, open My Computer, then type in location: ftp://yourdomain.com
and press enter.
you will be asked for ure usn password. Supply that, check 'save password' and then logon.
You should see ure website's root directory. You can upload your scripts/packages/cms/code here and you can acces that via the web.
If you have problems starting out, I suggest using godaddy's one click installs. They will install the whole system for you (depending on what you chose).
It becomes really easy to maintain ur website if you know ssh and vi.
Hope that helps.
Bye.
