Sensor shield V4 need documentation, etc...

I just received a sensor shield V4 and a sound sensor with no documentation. I found a sketch that is for using the sound sensor but all the sketch does is blink the LED. I am looking for any documentation to use the shield (properly) and any other sketches. I am still new to this and any help would be appreciated. (I have used Adafruit motor and WAV shields that work very well and comes with great documentation so I am surprised at the small amount of info for the sensor shield)
Thank you!
