DuckDNS docs: json instead of YAML

[silvrr]

This is the official documentation for your install method,

Installing TLS/SSL using Let's Encrypt

This one is easier to implement IMO

A more lightweight Let's Encrypt + DuckDNS setup

I wrote a quick tutorial on how to set up Let’s Encrypt and DuckDNS without needing to expose Port 80 to the outside world using the “dehydrated” script instead of the heavy weight certbot tool. https://www.splitbrain.org/blog/2017-08/10-homeassistant_duckdns_letsencrypt The advantage of using DNS challenges is that I do not need to worry about what runs on port 80 (in my case it’s emulated_hue for Google Home) when doing the certificate renewal. I hope it’s useful for others.
