[SOLVED] Point DNSMASQ to another DNS Server?

I have a simple situation here, but one that i can't quite figure out.

I am trying to set up dnsmasq for dns and dhcp. DHCP I was able to do easily.

DNS, though, is a bit different.

I would like all local computers to use the DNSMASQ machine as their DNS Server, and in turn have that use another DNS Server (AD Domain Controller) 172.16.12.5 as the root-hint ... or ... not really sure how to explain this.

I know it's only a few lines of code but I can't find exactly what I want to put in here.
