How do I get started as a premium (paid 1 year) member?

Once I paid, I was taken to a download of the "wpmudev Dashboard plug-in". I hit download, it downloaded, but where, actuall,y do I go within "my wpmudev dashboard" to install and use this plug-in. I am familiar with the usual Wordpress Dashboard but this is new so pardon my newbie question.
Does the plug-in get added to the plug-ins folder of each of my Wordpress installations? Is that the idea?
