Since Let's Encrypt's client was renamed to Certbot, I think there might be some places to change the docs/comments.
While their client is now called certbot, the CA itself is still called "Let's encrypt". Caddy was never using any official clients, but a go implementation of the acme protocol. I think it is still valid to call it "Let's encrypt", but to be fair, it should work with any acme CA.
Thanks for your suggestion! Version 0.9 will no longer use the term "letsencrypt" unless we specifically mean that CA, but already Caddy works with any ACME-enabled CA.
Awesome!
