Syntax for config.yaml is not apparent / not as advertised

In /config.yaml.dist it's advertised that to find out the expected syntax for the values in the yaml file, "all the options available can be seen with ./dnsproxy --help". The values offered by --help are not actually valid. I dove into /main.go to try to back into the expected yaml syntax, and dnsproxy appears to parse/accept the yaml file, but it does not start as expected.

  1. Please consider publishing the yaml syntax.
  2. In my case, I'm attempting to start a docker container of adguard/dnsproxy with multiple secure DNS methods and forwarding them upstream to a local DNS server. What is it expecting that I am not properly specifying?

config.yaml:

upstream:
  - "10.1.0.3:53"
fallback:
  - "8.8.8.8"
https-port:
  - 443
tls-port:
  - 853
quic-port:
  - 1853
dnscrypt-port:
  - 2853
ratelimit: 20
upd-buf-size: 1024
ratelimit-subnet-len-ipv4: 24
ratelimit-subnet-len-ipv6: 64
refuse-any: true
tls-cert: "/etc/letsencrypt/live/domain.name.replaced/fullchain.pem"
tls-key: "/etc/letsencrypt/live/domain.name.replaced/privkey.pem"

log from dnsproxy starting with that config:

Thanks.

Ditto... options for the config.yaml are not documented. Very frustrating!
