 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.
