 # Description
 
-This app creates a simple CLI tool used to create and verify multi-factor auth codes using Bandwidth's Multi-Factor Auth API. The app will prompt the user for their phone number, followed by their preferred method of code delivery; either messaging or voice. The app will then text or call the phone number provided with a 6 digit MFA code that the user can enter back into the CLI to verify.
+This sample app is a command line tool that sends and verifies multi-factor auth codes using Bandwidth's Multi-Factor Auth API.
+
+The app asks for a phone number in E.164 format and whether to send the code by `messaging` or `voice` (`messaging` if left blank). It then texts or calls that number with a 6 digit code, asks you to enter the code, and checks it. The app exits with status `0` if the code is verified and `1` otherwise.
 
 # 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.
+In order to use the Bandwidth API users need to set up the appropriate applications 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).
+This app needs two applications, one for each delivery method. 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 once selecting Messaging, and once selecting Voice. This app doesn't receive any callbacks, so the callback URLs can be left as placeholders.
 
 For more information about API credentials see our [Account Credentials](https://dev.bandwidth.com/docs/account/credentials) page.
