 ### Post install

 If backups are configured, you'll need to run:
+
 ```
 borgmatic init --encryption repokey-blake2
 ```

 then restart `borgmatic`.

 To join the Tailscale network, run:
+
 ```
 tailscale up --login-server https://headscale.vimium.net
 ```
+
 then visit the URL, SSH onto `vps1` and run `headscale --user mesh nodes register --key <key>`.

 The new node can optionally be given a friendly name with `headscale node rename -i <index> <hostname>`.
