There is a slot on the side of the phone where you can insert a MicroSD card. Remove the back cover (there is a slot at the top, near the camera, where you can pry the cover off with your finger) and as you're looking at the battery, the MicroSD slot is to your left, just above the camera button. Just slide the memory card in there.
You should turn the phone off before inserting a MicroSD card. Without the back cover on, the battery won't make a tight connection, and if it jiggles at all it will lose power and shut off anyway.
