The objective of let's encrypt and the acme (automated certificate management environment) protocol is to make it possible to set up an https server and have it automatically obtain a browser-trusted certificate, without any human intervention. this is accomplished by running a certificate management agent on the web server.

this agent is used to:

- automatically prove to the let's encrypt ca that you control the website
- obtain a browser-trusted certificate and set it up on your web server
- keep track of when your certificate is going to expire, and renew it
- help you revoke the certificate if that ever becomes necessary.
this package contains the documentation.
