+# About
+This test application is created for testing/demonstrating the BH1750FVI driver.
+It uses the default device parameters as specified in
+`drivers/bh1750fvi/include/bh1750fvi_params.h`. To override these setting, you
+can simply do this by defining these parameters as compiler flags while uilding,
+e.g.:
+```
+$ CFLAGS="-DBH1750FVI_PARAM_I2C=I2C_DEV(1)"" make all
+```
+
+# Usage
+Simply flash this example to your board and it will read the sensor value 5
+times per second and print the sampled value to STDIO. You can verify the values
+by simply covering the sensor or holding it in front of a bright light and see
+the change in the sensor readings accordingly.
