Pro Tools 10 & Omnisphere

Hello,

So I downloaded Omnisphere onto my 2nd Internal (Non-Startup) Drive on my Mac Pro. I opened Pro Tools and looked for it after creating an instrument track. It was not there. I suppose I need to move one of the Omnisphere folders into a Pro Tools Plug-in folder or something of the like, but I am not sure which one. Any help would be appreciated.

Thanks
