Connecting display with arduino uno!

I got two new 2.4 inch TFT touch Screen LCD Arduino Shield. One is for connecting with mega and the other is uno. Please , guide me in connecting them.

Looks like you write a file to a SD and insert it in your shield.

Upload appropriate sketch and library to your UNO or MEGA. Contact source where shield was purchased from - for the sketch.

Remove power, plug shield into UNO or MEGA.
