+===============================
+
+NAME
+----
+cdist-type__systemd_resolved - Configure system to use systemd-resolved.
+
+
+DESCRIPTION
+-----------
+*systemd-resolved* is a systemd service that provides network name resolution
+to local applications via a D-Bus interface, the resolve NSS service
+(nss-resolve(8)), and a local DNS stub listener on 127.0.0.53.
+
+This type enables and starts this type, and helps with some minimal
+configuration. In particular, systemd-resolved has four modes of handling the
+`/etc/resolv.conf` file: stub, static, uplink and foreign. See the
+systemd-resolved(8) manpage for details. By default, this type uses stub mode:
+if you need another one, please provide an implementation in this type!
