Syncthing was installed with `sudo apt install syncthing` after all packages and lists were updated.

A syncthing user and group were created to run the `systemd` service, and they were given ownership of a directory

The systemd service was edited to include the `--home=/opt/syncthing` path, and the service was started after `sudo systemctl daeon-reload`

The config was updated to replace the default gui IP (127.0.0.1) with 0.0.0.0 to make the gui accessible to other computers
