 Operating systems like Ubuntu 18.04 and greater that ship with systemd-resolved configured to run by default will need this disabled and to manually configure your resolv.conf if you are running PowerDNS Authoritative on default ports.
 You can look at the [test cookbook](https://github.com/dnsimple/chef-pdns/blob/master/test/cookbooks/pdns_test/recipes/disable_systemd_resolved.rb) for a simple example of how to handle this.

 To fully configure an authoritative server you need to add at least 3 resources to your recipe, `pdns_authoritative_install`, `pdns_authoritative_config` and `pdns_authoritative_service`. If you want to install any backend other than the default (bind) for the authoritative server you need to install the corresponding packages for the backend you want. There is an example for a postgresql backend in `test/cookbooks/pdns_test/recipes/`.
 
-For a recursor use the `pdns_recursor_install`, `pdns_recursor_config`, and `pdns_recursor_service` resources in your wrapper cookbooks to install, configure, and define PowerDNS recursors. Set the different properties on the resources according to your install and configuration needs. You can see a good example of this in `test/cookbooks/pdns_test/recipes_recursor_install_single.rb`
