### Photo logs of assembling the case

We're going to begin by putting together the right half of the split keyboard.

Due to the design, please refrain from installing any screws into the bottom right opening.

Place the PCB on top of the bottom case.

Secure the PCB in place by assembling the M2 nuts.

Double check the polarity indicated on the PCB

Place the battery next to the controller

Then we will start to insert the key switches and keycaps to the top plate.

Secure the top case to the keyboard by installing the screws into the bottom case.

The right side of the keyboard is ready :)
