+Create a Blue Button Sandbox Account 
 ---------------
-    
+Create an account at the link below, and register your test application, to get your Blue Button Sandbox Credentials which will allow you to 
+access the Blue Button synthetic data.  These credentials will be necessary to run this sample application as well as 
+utilize the Blue Button data within your own applcation.  See the section below 'Running the Back-end & Front-end'.
+
+https://sandbox.bluebutton.cms.gov/v1/accounts/create
+
+To ensure this sample application will work properly, make sure that when you register your application you add 
+the following url (see below) under the 'Callback URLS/Redirect Uris' section:
+
+http://localhost:3001/api/bluebutton/callback/
+
+When you are ready to run your own application, you can change this value to the url that you need.  
+Just log into your Blue Button Sandbox account and select 'View/Edit App->'.
+
+Setup Docker & Node-js
+---------------
+
+Install and setup Docker.  Go to https://docs.docker.com/get-started/ and follow the directions.
+
+Download and install node.  Go to https://nodejs.org/en/download/ and follow the directions.
+
+Running the Back-end & Front-end
+---------------
+
+Once you have Docker and Node installed and setup then do the following:
+
     copy server/src/configs/sample.config.ts -> server/src/configs/config.ts
-    replace the secret variables with the ones for your application
+
+Make sure to replace the clientId and clientSecret variables within the config file with
+the ones you were provided, for your application, when you created your Blue Button Sandbox account.
+
 
     copy server/src/pre-start/env/sandbox.sample.env -> server/src/pre-start/env/development.env
 
     docker-compose up -d
 
+This single command will create the docker container with all the necessary packages, configuration, and code to 
+run both the front and back ends of this sample application.
+
+To see the application in action open your browser and enter the following URL:
+
+http://localhost:3000
+
+To see the process of authenticating with Blue Button via Medicare.gov and retrieve EoB data just click on the 'Authorize' button.

-Blue Button 2 Sandbox user that has PDE EoBs.  An example of a user with this
+Blue Button Sandbox user that has PDE (Part-D Events) EoBs (Explanation of Benefits).  An example of a user with this
 data would be:  BBUser29999 (PWD: PW29999!) or BBUser29998 (PWD: PW29998!)
