	You list the IP addresses of the caching nameservers in the 
/etc/resolv.conf files for your clients and other servers.

	Even the authoritative master & slave servers are going to have 
other processes which will need caching DNS service, so you can 
either point their resolvers at the caching nameservers as well, or 
you can run additional copies of BIND configured for caching-only 
that listens only to the 127.0.0.1 interface, etc....

	Everyone will know about them, through the /etc/resolv.conf files.

	I highly recommend the resources at <http://www.dns.net/dnsrd/>. 
It is the canonical DNS Resources Directory, after all.  There's 
plenty of online documentation linked from 
<http://www.dns.net/dnsrd/docs/>.

	Of course, there's also the stuff at <http://www.bind9.net/>.
