 ## Introduction
 * **Authentication** is used by a server when the server needs to know exactly who is accessing their information or site.
 * **Authorization** is a process by which a server determines if the client has permission to use a resource or access a file.
 
-Creating an authentication and authorization strategy is always a complex process. A number of quick questions immediately arise:
+The inherent complexity of crafting an authentication and authorization strategy raises a barrage of immediate questions:
 
-* Should we set up separate services for authentication and authorization
-* How do we handle access token creation and who is responsible for this
-* Should we alter our REST service to support authorization flow
+* Would it be beneficial to utilize separate services for authentication and authorization purposes?
+* What is the process for creating access tokens, and who is tasked with this responsibility?
+* Is it necessary to adapt our REST service to support an authorization flow?
 
-The `auth-server` project tries to accumulate all of those capabilities and act as a transparent authentication and authorization proxy middleware.
+The `auth-server` project aims to address these concerns by serving as a transparent authentication and authorization proxy middleware.

+To install the latest stable version of Go, visit the [releases page](https://golang.org/dl/).
+
+* Read the following [instructions](./secrets/README.md) to generate keys required to sign the token. Specify the location of the generated certificates in the service configuration file. An example of the configuration file can be found [here](config/service_config.yml).
+
+* The following example shows how to run the service using a configuration file:
+    ```
+    ./auth -c service_config.yml
