Quad9 and DNS-over-TLS

[strangegopher]

Hi,

I just did some quick google search and saw Quad9 supports DNS-over-TLS.

I saw config file for unbound: https://dnsprivacy.org/wiki/display/DP/Using+Unbound+as+a+DNS+Privacy+server

But on the forums I found different config files.

Which one is correct?
