+## NetworkManager default configuration
+
+Without configuration, Netplan will not do anything. Therefore, on Desktop
+systems, a useful configuration snippet to just bring up networking via DHCP is
+as follows:
+
+```yaml
+network:
+  version: 2
+  renderer: NetworkManager
+```
+
+This will make NetworkManager manage all devices and by default. Any ethernet
+device will come up with DHCP, once carrier is detected. This is basically
+Netplan passing control over to NetworkManager at boot time.
+
+You can still define any more specific IDs in you Netplan configuration, to
+configure interfaces individually, according to Netplan's [YAML reference](/netplan-yaml/).
+
+When NetworkManager's [Netplan desktop integration}(/netplan-everywhere/) is
+activated, NetworkManager will automatically create specific Netplan IDs for
+each of its connection profiles.
+
+This configuration snippet is shipped by default on Ubuntu Desktop systems
+through the [ubuntu-settings](https://launchpad.net/ubuntu/+source/ubuntu-settings)
+package as `/usr/lib/netplan/00-network-manager-all.yaml`.
