https://etcher.io is a great tool for this
Add ssh and wpa-supplicant.conf files to boot partition of sd card so you can run headless.
Details here https://caffinc.github.io/2016/12/raspberry-pi-3-headless/
At the start it will be helpful to have the pi hooked up to an HDMI screen and a USB keyboard.
(For Localization: All locations will take a long time, maybe skip this and just select your own region )
sudo raspi-config
Change password: sleep
Network > Hostname (norns)
Network > Wifi (set SSID/password)
Interfacing > SSH (on)
Advanced > Expand File System

exit, reboot
sudo reboot
ifconfig
sudo passwd root
logout, the login again as root
usermod -l we -d /home/we -m pi
groupmod --new-name we pi
exit, login as we
sudo passwd -l root
disable need for passwd with sudo
(sudoers filename will vary - tab to autocomplete or ls /etc/sudoers.d/ to check the filename)
sudo nano /etc/sudoers.d/010...
change 'pi' to 'we'
SSH to the pi with a new terminal. (use ifconfig to check IP if needed)
At this stage, using ssh to log in remotely w/ we@norns/sleep makes it easier to cut and paste things.

Choose which linux source you want to use from the options below.
_Note the release monome linux source is a older version that won't work on a Raspberry Pi 3b+ _
Note: The compile process will take about 90 mintues or more on a RasPi 3b

git clone https://github.com/monome/norns-image.git
cd norns-image
do not run setup.sh YET
nano setup.sh
comment out dhcp/interfaces copies so it does not hose your wifi when you install
#sudo cp config/dhcpcd.conf /etc/dhcpcd.conf
#sudo cp config/interfaces /etc/network/interfaces
#sudo systemctl disable dhcpcd.service
nano config/norns-init.service
comment out these lines for analog gain stage (put # in front, we dont want any i2cset)
#ExecStart=-/usr/sbin/i2cset -y 1 0x28 0x00
#ExecStart=-/usr/sbin/i2cset -y 1 0x28 0x40
may also need to comment out Mixer line depending on your soundcard needs
nano config/norns-jack.service
change to your soundcard if needed. if you're using a usb soundcard, you'll probably need to change buffer size (-p)
nano config/norns-maiden.service
change exec to maiden (not maiden.arm) Also get the file path right
ExecStart=/home/we/maiden/maiden -fd 3 -app ./app/build -data /home/we/dust -doc /home/we/norns/doc
nano scripts/init-norns.sh
comment out i2cset for analog gain stages again
#sudo i2cset -y 1 0x28 0x00
#sudo i2cset -y 1 0x28 0x40
may need to comment out Mixer line depending on your DAC setup
