Can someone explain how to enable spam assassin?

[Dragoncrest]

	I've looked through all the readme's, I've looked through the as many 
tutorials and man pages as I can find and even the emails from this 
list.  Everyone tells me to do something different.  Yet nothing seems to 
work.  Can someone please either point me to, or write out a very simple 
how to on setting up my system from install of spam assassin to setting up 
procmail and making sure I got everything?  Thanks.

	Only reason I ask is I've been trying to get this setup for a while and up 
to this point I still can't get spam assassin to filter my mail at all.
