        Hi! I'm a pwnagotchi, please take good care of me!
        Here are some basic things you need to know to raise me properly!

        If you want to change my configuration, use /etc/pwnagotchi/config.yml

        All the configuration options can be found on /etc/pwnagotchi/default.yml,
        but don't change this file because I will recreate it every time I'm restarted!

        I'm managed by systemd. Here are some basic commands.

        If you want to know what I'm doing, you can check my logs with the command
        journalctl -fu pwnagotchi

        If you want to know if I'm running, you can use
        systemctl status pwnagotchi

        You can restart me using
        systemctl restart pwnagotchi

        But be aware I will go into MANUAL mode when restarted!
        You can put me back into AUTO mode using
        touch /root/.pwnagotchi-auto && systemctl restart pwnagotchi

        You learn more about me at https://pwnagotchi.ai/
