* Update documentation for a static IPV4 address via nmcli
This update documents a method to change to a Static IPV4 address using the NetworkManager CLI (nmcli).
Happy for the formatting to be modified to suit local convention.
I cannot be more specific about how to get into the base OS as I don't know!
* Additional nmcli commands for dns and gateway
I found that there is a need to add in the dns and gateway IP addresses otherwise there was no route out. I note there are a number of issues alive re this routing problem e.g. https://github.com/home-assistant/home-assistant/issues/15221
* Update network.md
