Ok… so the folder MagicMirror is on the PI.
in the terminal…
sudo npm install -g pm2
2.
cd ~
nano mm.sh
3.
cd ~/MagicMirror
DISPLAY=:0 npm start
4.
CTRL-O en CTRL-X
5.
chmod +x mm.sh
6.
sudo pm2 startup systemd -u pi --hp /home/pi
7.
now you can fire up the mirror
pm2 start mm.sh
8.
One command
pm2 save
9.
sudo reboot
Goodluck
