Setting up netboot on OSX Server


I would like to start using NetBoot for a few Macs I am managing. I would like to set up the NetBoot Server on the OSX Server (10.6.8) that I have available to me. Can someone provide instructions or a website with instructions on setting the server side of NetBoot up? I am having trouble finding clear-cut examples.

I would also appreciate any info on setting up the clients as well, but server comes first!
