+# About
+This is a manual test application for the LPS331AP pressure sensor driver.
+
+# Usage
+This test application will initialize the pressure sensor with the following parameters:
+ - Sampling Rate: 7Hz
+
+After initialization, the sensor reads the pressure and temperature values every 250ms
+and prints them to the STDOUT.
