First of all, you need to ensure that SSH access is enabled at your service provider (in your case, GoDaddy - see this URL).
Then, if you are on Windows, you will need to download a program called PuTTY. It is the most popular SSH program for Windows.
If you are on Linux or OSX, they usually have SSH built in (just run ssh)
Once you are logged in to your server (using the details that GoDaddy give you) you should be able to follow the instructions on that page.
However, by the looks of the software you're trying to install, it won't install on shared hosting, only a dedicated server (but I could be wrong).
