+# About
+This is a manual test application for the MPL3115A2 driver.
+
+# Usage
+This test application will initialize the MPL3115A2 sensor with the following parameters:
+ - oversample ratio 128
+
+After initialization, the sensor reads the pressure and temperature values every 1s
+and prints them to STDOUT.
