how to configure procmail? I need step by step guidance.

["Technical" <technical sojourn dyndns org>]

I read the guide.  I tried to follow the suggestions from www.procmail.org
and and it is not working.  I just want to setup procmail.

I need step by step guidance:

Where should the .forward file be and what should it contain?
where should the .promailrc file be and what should it contain?
could someone give me a sampple recipe... say I only want to delete
messages that come from dummy wert com?
