 # Description
 
-A short description of your sample app and its capabilities.
+A simple dial pad application used to create calls using our WebRTC SDK.
 
 # Pre-Requisites
 
-In order to use the Bandwidth API users need to set up the appropriate application at the [Bandwidth Dashboard](https://dashboard.bandwidth.com/) and create API tokens.
-
-To create an application log into the [Bandwidth Dashboard](https://dashboard.bandwidth.com/) and navigate to the `Applications` tab.  Fill out the **New Application** form selecting the service (Messaging or Voice) that the application will be used for.  All Bandwidth services require publicly accessible Callback URLs, for more information on how to set one up see [Callback URLs](#callback-urls).
+In order to use this sample app, your account must have In-App Calling enabled. You will also have to generate an auth token using our Identity API.
 
 For more information about API credentials see our [Account Credentials](https://dev.bandwidth.com/docs/account/credentials) page.

-# Callback URLs
-
-For a detailed introduction, check out our [Bandwidth Product Specific Callbacks](https://dev.bandwidth.com/docs/messaging/webhooks) page.
-
-Below are the callback paths:
-* **Should follow `/callbacks/{direction}/{service}` conventions**
-* `<add other callbacks>`
-
-## Ngrok
-
-A simple way to set up a local callback URL for testing is to use the free tool [ngrok](https://ngrok.com/).  
-After you have downloaded and installed `ngrok` run the following command to open a public tunnel to your port (`$LOCAL_PORT`)
-
-```sh
-ngrok http $LOCAL_PORT
+REACT_APP_IN_APP_CALLING_TOKEN             # You Identity Token
+REACT_APP_IN_APP_CALLING_NUMBER            # A valid phone number on your account
 ```
-
-You can view your public URL at `http://127.0.0.1:{LOCAL_PORT}` after ngrok is running.  You can also view the status of the tunnel and requests/responses here.
