+### Launch Tailscale VPR on login
+
+This script is designed to be run on login on an MDM asset to ensure Tailscale launches and authenticates Tailscale, we use this where a client has a requirement for all external server access has to be encrypted over a tunnel.
+
+The script pings the exit node or a server which is online and verifies a connection, if it cannot find a connection after a short delay to force the authentication using an AUTH key.
+
+#### Options
+
+* TAILSCALEAUTHKEY="tskey-auth-hdhhj8hjdhj-dwwdgewghEHWEH90238909"
+* TSSERVERIP="100.100.100.100"
+##### Command to execute
