+# About
+This is a manual test application for the PULSE_COUNTER driver.
+
+# Usage
+This test application will initialize the PULSE_COUNTER sensor with the configuration
+as specified in the default `pulse_counter_params.h` file.
+
+If you want to use this test application with different parameters, you can
+simply override the default PULSE_COUNTER_PARAMS.
+
+After initialization, the sensor reads the pulse counter values every second and
+prints them to STDOUT.
