[arch-general] How to autostart ufw on system startup?

Hello! How do I get ufw to start automatically upon Arch system startup? The Arch wiki Uncomplicated Firewall pages says: "Start ufw as systemd service to have it running and enable it to make it available after boot. " How do I do that? Then it shows an example configuration (can't I just keep the default: deny all incoming, allow all outgoing)? Then it says: "The next line is only needed *once* the first time you install the package: # ufw enable" That does not seem to be true - I have to do "sudo ufw enable" every time I restart the system. Then, it says: "Then enable the ufw service with systemctl." How? Bottom line: ufw works okay, I just want it to start automatically when the system starts up.
