Motor Shield documentation?

Hello,

I just got the Motor Shield v2 http://www.seeedstudio.com/wiki/Motor_Shield_V2.0 for Arduino Uno.

I works with the demo code I found on the website. This is the first time I have used a shield. Where do I find information about the available functions and commands in the library and how to use them?

Thanks!
Stephen

Never mind I just found the library code! Thanks.
