# See which letter your newly inserted SD Card has:
sudo fdisk -l  # or lsblk

# Format sd card
sudo umount /dev/sdX
sudo mkfs.vfat /dev/sdX -I

# Get some help text about supported options

# Template:
sudo sdcard/write.sh /dev/sdX [board] [os] [rootfs]

# Example
sudo sdcard/write.sh /dev/sdX rpi-3 hypriotos docker-multinode

# The installer will ask you if you want to erase all data on your card
# Answer y/n on that question
