+## About
+This is a test application for the VCNL40X0 proximity and ambient light sensor.
+
+## Usage
+
+After initialization, every 2 seconds, the application:
+* reads the proximity (cts);
+* reads the ambient light (cts);
+* reads the illuminance (computed from ambient light by dividing it by 4);
+* those values are printed to STDOUT.
