Setup completed successfully.

You can now visit the following locations:
- https://public.$DOMAIN - Bypasses Authelia
- https://traefik.$DOMAIN - Secured with Authelia one-factor authentication
- https://secure.$DOMAIN - Secured with Authelia two-factor authentication (see note below)

You will need to authorize the self-signed certificate upon visiting each domain.
To visit https://secure.$DOMAIN you will need to register a device for second factor authentication and confirm by clicking on a link sent by email. Since this is a demo with a fake email address, the content of the email will be stored in './authelia/notification.txt'.
Upon registering, you can grab this link easily by running the following command: 'grep -Eo '"https://.*" ' ./authelia/notification.txt'.
