How do I install the WPMU DEV dashboard plug in in my website

I go to the WPMU DEV website and push down load for the WPMU DEV dashboard and I get a download of compressed files in my browser but I have no instructions as to how to take this information and install it on my website. Please advise instructions as to how to take the downloads and install them on my website so i can attached my website to my WPMU DEV membership website and open up the pro WP Smushit plug in. Thanks, Adam
