+# About
+This is a manual test application for the L3G4200D gyroscope driver.
+
+# Usage
+This test application will initialize the pressure sensor with the following parameters:
+ - Sampling Rate: 100Hz
+ - Bandwidth: 25Hz
+ - Scale: 500DPS
+
+After initialization, the sensor reads the angular speed values every 10ms
+and prints them to the STDOUT.
