-# Caveats:
-# 1. the keys/certs cannot be produced by unbound. You can use dnscrypt-wrapper
-#   for this: https://github.com/cofyc/dnscrypt-wrapper/blob/master/README.md#usage
-# 2. dnscrypt channel attaches to an interface. you MUST set interfaces to
-#   listen on `dnscrypt-port` with the follo0wing snippet:
-# server:
-#     interface: 0.0.0.0@443
-#     interface: ::0@443
-#
-# Finally, `dnscrypt` config has its own section.
