How to connect Apple Studio Display to MacBook Pro?

What do I need to connect my Macbook Pro to my Apple Studio Display (clear plastic, 3-legged, LCD) and use it as a second screen?

I have Unibody MacBook Pro 15-inch (Processor 2.53 GHz Intel Core 2 Duo, Memory 8 GB 1067 MHz DDR3, Software OS X 10.9.5 (13F34), Storage 25.75 GB of 319.21 GB)

I appreciate any reply.
