+>> *** Booting Zephyr OS build 596dd391de46 ***
+
+                Welcome to T-Mobile - Internet of Things
+
+This application aims to demonstrate the Gecko's Energy Mode 2 (EM2) (Deep Sleep
+Mode) sleep/wake capabilities in conjunction with the high/low illuminance
+threshold detection circuitry of the TSL2540 light sensor integrated into the
+tmo_dev_edge.
+
+
+While observing the console output, increase the light illuminating the
+tmo_dev_edge's light sensor until the sensor readings at or above the high
+threshold are displayed. Reducing the intensity of the light source will cause
+the alerts to cease. Casting a shadow over the light sensor will cause sensor
+readings at or below the low threshold to be displayed.
+
+
+Awaiting TSL2540 illuminance threshold-high/threshold-low alerts
