Question : How do I configure Quality of Service on a Cisco 3550 Switch?

I want to configure Quality of Service for my Cisco VOIP. I have a Cisco Call Manager Express / Unity Express on a Cisco 2801 Router. I am using a Cisco 2651XM Router for the connection to my ISP (3MB Circuit), and Cisco 3550 switches for my LAN. Can anyone provide an example of what i need to do to configure this. I'm new on configuring qos, and am having problems finding documention that shows the configuration and explains what the commands do. Any assistance would be greatly appreicated. Thanks.
