 If you don't want to worry about SSL certificates, you can use the built-in Let's Encrypt auto-cert feature. This requires that you have both port 80 (HTTP) and port 443 (HTTPS) open to the world. Also, your domain name should point to your IP address where [Rdio Scanner](https://github.com/chuot/rdio-scanner/) is running. The advantage of this approach is that everything is done automatically, no certificate request, no certificate renewal.

 If you don't want to worry about SSL certificates, you can use the built-in Let's Encrypt auto-cert feature. This requires that you have both port 80 (HTTP) and port 443 (HTTPS) open to the world. Also, your domain name should point to your IP address where [Rdio Scanner](https://github.com/chuot/rdio-scanner/) is running. The advantage of this approach is that everything is done automatically, no certificate request, no certificate renewal.
