istat problem

Call me an idiot but this is my first macbook and im having a problem

Ive installed istat pro however I cant seem to get it to appear on my desktop, all i have is the options page, how do i get it onto my desktop?

thanks people

 

thanks guys but im having no luck, its not in my list of widgets yet when i go to system preferences its displayed at the bottom...

Im guessing ive gone wrong somewhere when installing it...
