I use acme-tiny and confirm it is good. But there is still significant work to do to get a working certificate and the documentation is lacking significant details. I have my own recipe documentation that I should publish. Apart from this, this is the only script out there that did cut it for me. Note that the update process needs to be automated because let's encrypt certificates last only 3 months as I have read.
