Hi, It's a pretty straightforward. I use the colours I used. Put the frame face down on your table. Make sure you followed the guide with the screen to connect the 2 power wires. Take the largest red part and place it over the screen so the screw holes match. Now put the black part on it and use four screws. Before closing the lid make sure you secure the screen cable in the box without over bending it. In picture 4 you can see hos I did it. Close the lid and screw it down.
