See http://pdns.powerdns.com and especially 
http://pdns.powerdns.com/doc & http://pdns.powerdns.com/doc/pdns.pdf

For those not reading documentation, and installing from the .tar.gz:

	$ ./choosepaths 
	   or
	$ editor pathconfig

	and then, as root

	# ./installer

If you installed the RPM or the .deb, you can skip the above.

If this went ok:

# /etc/init.d/pdns monitor

Now add "bind-example-zones" to pds.conf, and query your nameserver:

$ host www.example.com 127.0.0.1
www.example.com		A	1.2.3.4

and NOW read the documentation!
