1. Download .img file from octoprint.org
2. Burn .img file to microSD card with WIN32DiskImager
3. Modify octopi-wpa-supplicant.txt with notepad(win10) with my local wifi settings, so I can run it headless(no HDMI out).
4. Insert microSD into RPI4, power on.
5. SSH into my router(RPI0W) use arp -a command to list connected devices, find octopi's IP address.
6. SSH into octopi, user name:pi, password:raspbery.
7. Customize your own options with "sudo raspi-config.
8. Set up OctoPrint through its web interface.
