It's probably better that you search google first.

Well there are various tutorials, none of which I can find right now,
but a picture paints a thousand words...
This diagram is a good place to start as it's simple, although probably
out of date:
http://www.docum.org/docum.org/kptd/
Once you've got your head around that, this is the fully comprehensive
one, but tougher for beginners:

If you've got any specific questions, then please ask!

Currently the best one is at http://inai.de/images/nf-packet-flow.svg
by Jan ENGELHARDT.
He is a netfilter developer.
http://www.ipszilon.iif.hu/iptables/tuzfal-kadlec.pdf
The other (simpler one) I would recommend:
Page 11 of http://www.ipszilon.iif.hu/iptables/tuzfal-kadlec.pdf.
It is in Hungarian.
