Provide pointer to acme-dns solutions

I have some servers that aren't really web servers, and I'd like to be able to use the acme-dns challenge system to get certificates for them.

But, I can't find an easy path from the website to how to do dns.

@SwartzCr pointed me to https://github.com/lukas2511/dehydrated/wiki/Examples-for-DNS-01-hooks on irc, and it has the answer for my case (I use pdns), but it'd be helpful if there was a good link to that from the certbot website/documentation.
