# To '''enable the CM4 to be updated via rpiboot''', You have to put a jumper over the pins of "nBOOT" and "GND" on the 6-pin header.
# Please use only the '''screws(M2x3mm) for mounting the SSD''' come with this kit. Other screw size(length>3mm) will damage your Micro-SD card or the card socket!!!
