+## Automatic Startup
+
+### Session-based
+
+LXDE can start the kiosk automatically by creating this file:
+
+Create/edit the file: `/home/pi/.config/lxsession/LXDE-pi/autostart`
+
+```BASH
+/usr/bin/grafana-kiosk --URL https://bkgann3.grafana.net/dashboard/db/sensu-summary --login-method gcom --username bkgann --password abc123 --kiosk-mode full --lxde
+```
+
+#### Session with disconnected "screen"
+
+Alternatively you can run grafana-kiosk under screen, which can very useful for debugging.
+
+Create/edit the file: `/home/pi/.config/lxsession/LXDE-pi/autostart`
+
+```BASH
+screen -d -m bash -c "/usr/bin/grafana-kiosk --URL https://bkgann3.grafana.net/dashboard/db/sensu-summary --login-method gcom --username bkgann --password abc123 --kiosk-mode full --lxde"
