[Icecast] install help

[Dean Machine]

I am setting up an audio stream for our local LPFM radio station on Mac 
OS X.  I have a Shoutcast server up and running but would like to 
explore Icecast as well.  I am but a novice programmer and need to find 
a source of step by step instructions.  I have downloaded the server 
and other necessary packages but have been unable to put the pieces 
together.  Can you direct me to a source of "simple" instructions?  
Thanks for any help.
