+Host (broadcast) mode with an SSID based on a unique id (the last four of your
+Pi's serial number). No input devices or displays necessary. Otherwise this is
+a base install of the current Raspbian Stretch, up to date as of the date of
+this release.

 RESETTING THE DEVICE:
 
-== If GPIO 18 is pulled HIGH for 10 seconds or more the Raspberry Pi will reset all settings, reboot, and enter "Configuration Mode" again. It's useful to have a simple button wired on GPIO 18 to reset easily if moving to a new location, or if incorrect connection information is ever entered. Just press and hold for 10 seconds or longer.
