There is not very much too this step at all, but it is fairly tricky. Mainly due to the 0402 sized resistor.
An 0402 resistor is 40 thousandth of an inch by 20 thousandth of an inch. That is 1mm x 0.5mm in metric. Anyway all you have to do in this step is get the suitable LCD from eBay and solder in a 1K0 resistor in the location called R3 as shown in the photo.
