I noticed [this PR](https://github.com/certbot/certbot/pull/2061) was merged recently, adding support for the dns-01 challenge to the cerbot/letsencrypt client. Is there any documentation for how to use this or how it works outside of the code? Looking forward to using the new challenge but just confused on how it works.

The PR added `DNS-01`-support to the ACME client. Unfortunately, that doesn’t mean (as far as I know) that `certbot` _itself_ can use it. The `certbot` code uses the ACME client to communicate with an ACME server, but needs the code to do that.

So this is one step in the direction of using the `DNS-01`-challenge in `certbot`, but isn’t there just yet.

Ah that makes more sense. Thanks for the explanation.
