+= Initial setup of SD card for Life Display
+
+Download Pi OS lite version from
+https://www.raspberrypi.com/software/operating-systems/
+
+unxz the image and use `dd` to write it to a SD card.
+
+Mount the SD card / and /boot on a directory under /mnt/, eg.
+
+sudo mkdir -p /mnt/d1/boot /mnt/d1/root
+sudo mount /dev/mmcblk0p1 /mnt/d1/boot
+sudo mount /dev/mmcblk0p2 /mnt/d1/root
+
+Run the ./setup.sh script, passing /mnt/d1/
+
+sudo ./setup.sh /mnt/d1/
+
+Edit /mnt/d1/boot/wpa_supplicant.conf and change the SSID and password to your AP.
+
+Optionally change the password of the life user by replacing the default password in
+/mnt/d1/boot/userconf with the output from:
+openssl passwd -6
+
+Unmount /mnt/d1/boot and /mnt/d1/root and insert the SD card into the Pi and boot it.
+
+It is best to do this with a display and keyboard so you can see what IP address is assigned,
+or deal with any unexpected errors.
+
+Now you can reboot, and it should show the IP address at the login prompt, depending on the
+timing of bringing up the network.
+
+Edit the hosts file to set the correct IP address.
+Run the setup.yml playbook to setup the life display and change the boot display settings.
+
+ansible-playbook -v -k ./setup.yml
+
+the SSH password will be the password you created for the 'life' user. Or the default of
+asdasdasd
+
+= Build sdl2-life
+
+It is easiest to just build the sdl2-life program on the Pi. The git repo has been checked
+out into /opt/sdl2-life/ and it should simply be a matter of running:
+
+ cd /opt/sdl2-life && go build
+
+to build it.
+
+= Final Steps
+
+At this point the system should be ready. You can run /home/life/run-life-server to test, and
+then reboot to make sure it starts on its own.
+
+If everything looks ok you can turn off the boot logo and text by editing /boot/cmdline.txt
+and adding:
+
+ logo.nologo console=null quiet
+
+to the end of the kernel boot cmdline. This does make it much harder to debug problems, but
+worst case you can mount the SD card on another system and remove those arguments to turn
+them back on.
