 ### Getting Started
 
-This most recent version of this package is implemented in [`SSL Server`](https://github.com/FirstTimeEZ/server-ssl) and you can use that to understand how it works if the `jsdoc` isn't enough information.
+```javascript
+import LetsEncryptDaemon from 'lets-encrypt-acme-client';
+```
 
-### Wild Card Certificates
+#### Simple Usage Example
 
-You can generate `Wild Card Certificates` if you are using a supported `DNS Provider`
+Create a `LetsEncryptDaemon` and then start the `Daemon`
+
+```javascript
+const daemon = new LetsEncryptDaemon();
+await daemon.startLetsEncryptDaemon(...); // You can only start this once, it will configure itself to run again.
+daemon.checkChallengesMixin(...); // You must check the HTTP-01 Challenges for each LetsEncryptDaemon
