+==============================
+
+NAME
+----
+cdist-type__systemd-network - Configure systemd.network(5) file.
+
+
+DESCRIPTION
+-----------
+
+This type allows you to configure network interfaces by generating a
+systemd.network(5) file. It will enable systemd-networkd, so be sure to remove
+any conflicting network configuration tool if appropriate!
+
+Note that the systemd.network(5) system is very complete, and this type does
+not aim at providing every possible option. Are currently available only the
+most common options: feel free to add anything you need to this type which
+hopefully will grow over time.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+description
+  A text field used when displaying details about this network.
+
+OPTIONAL MULTIPLE PARAMETERS
+----------------------------
+match-name
+  A text field that will be set in the `Name` option of the `[Match]` section.
+
+
+BOOLEAN PARAMETERS
+------------------
+ipv6ra-usedomains
+  Set the `UseDomains` option of the `[IPv6AcceptRA]` section to `True`.
