To clarify. To install the board, plug it into the ramps board. Then flash the firmware located here: http://forums.robo3dprinter.com/index.php?threads/marlin-firmware-10-9-13.1071/ with the arduino software. Open up Martin_LCD and the arduino software will load all the other required libraries. Hit the upload button and it should recognize the reprapdiscount lcd automatically once it reboots.
