The apt-cache description for the resolvconf package says you should 
look at the README file in /usr/share/doc/resolvconf for detailed 
instructions. Although I don't use resolvconf, I did examine the package 
and found that it employs debconf. This means that running "sudo 
dpkg-reconfigure resolvconf" should step you through series of screens 
for setting config options.
