+
+The purpose of the **`Auth` Application**
+is to have a complete separation of concerns between
+our 
+[**App**](https://github.com/dwyl/app)
+and any Authentication/Authorization code
+in order to: <br />
+
+**a)** ***Simplify*** the **code** in the _main_ 
+[**App**](https://github.com/dwyl/app)
+because there is no "User Management"
+to think about.
+
+**b)** ***Maximize privacy/security*** of any/all **personal data**
+that people using our App entrust in us
+by storing it in a totally separate 
+fully encrypted database.
+
+**c)** Minimize the number of environment variables
+in the main App so that _anyone_ can run it
+from scratch in less than 2 minutes.
+
+
+For better or worse,
+minimizing the number of environment variables 
+in the _main_
+[**App**](https://github.com/dwyl/app)
+means they have to go _somewhere_ ...
+that somewhere is right _here_!
