+# About
+This is a manual test application for the TCS37727 driver.
+
+# Usage
+This test application will initialize the TCS37717 sensor
+with the following parameters: Gain 4x, RGBC on, Proximity Detection off
+
+After initialization, the sensor reads the RGBC ADC data every 1s
+and prints them to STDOUT.
