 ## letsencrypt-cpanel
- cPanel/WHM plugin for Let's Encrypt client (uses Perl and WHM API) 
+This is a cPanel/WHM plugin for the [Let's Encrypt](https://letsencrypt.org/) client. This plugin uses Perl and the WHM API, and requires a server running cPanel and WHM on it.
+
+Support for service SSL certificates has been recently added, and is considered to be in beta. Please report any issues you find so that we may address them.

+If everything goes well, you will see a new icon in the `WHM >> Plugins` section. Existing certificates will be shown, and you will be able to register new SSL certificates for domains on the server that do not yet have SSL associated with it.
