To run the CLI without sudo, you have four options:
- Use setcap 'cap_net_bind_service=+ep' /path/to/program
- Pass the `--http` or/and the `--tls` option and specify a custom port to bind to. In this case you have to forward port 80/443 to these custom ports (see [Port Usage](#port-usage)).
- Pass the `--webroot` option and specify the path to your webroot folder. In this case the challenge will be written in a file in `.well-known/acme-challenge/` inside your webroot.
