 ### ADDITIONAL RECOMMENDATIONS ###
  - Remove the /etc/sudoers.d/010_pi-nopasswd file to require entering your password
    when performing any sudo/root commands:

      sudo rm -f /etc/sudoers.d/010_pi-nopasswd

  - You can customise the initial settings by running:

      node-red admin init

  - After running Node-RED for the first time, change the ownership of the settings
    file to 'root' to prevent unauthorised changes:

      sudo chown root:root ~/.node-red/settings.js
</code>

<code>
sudo systemctl enable nodered.service

sudo systemctl start nodered.service

</code>
