Caddy is amazing. I accidentally wiped my fairly complex nginx configuration (yay apt-get purge) and have been so spoiled by Guix that I did not care about etckeeper or ansible on my one Debian server.
Anyway I decided to try Caddy to quickly get up and running and had a good setup in minutes including certificates for multiple domains. Even added wildcard certificates which I never figured out with Lets Encrypt, just because I could.
And a special call-out to your dedication to providing amazing documentation. Caddy is what all projects should aspire to be.
