Install and Configure ZeroTier client

ZeroTier creates secure networks between on-premise, cloud, desktop, and mobile devices.
The official ZeroTier documentation provides a way to install ZeroTier through a single line;
curl -s | sudo bash
However, a recommended option would be to first download the same install script, review/validate it, then execute it;
curl -s -o; chmod +x
Once installed -
zerotier-cli status
(shows current node address and service status)
zerotier-cli join xxxxxxx
(joins network ID and outputs join status)
zerotier-cli leave xxxxxxx
(leaves network ID and shows status)
zerotier-cli listnetworks
(shows network IDs associated with, node, vMAC, and IP)
