 In this quickstart, you will use Azure App Configuration to centralize storage and management of application settings using the [Azure App Configuration JavaScript provider client library](https://github.com/Azure/AppConfiguration-JavaScriptProvider).
 
-The JavaScript App Configuration provider is a library running on top of the [Azure SDK for JavaScript](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/appconfiguration/app-configuration), helping JavaScript developers easily consume the App Configuration service. It enables configuration settings to be used like a Map.
+App Configuration provider for JavaScript is built on top of the [Azure SDK for JavaScript](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/appconfiguration/app-configuration) and is designed to be easier to use with richer features.
+It enables access to key-values in App Configuration as a `Map` object.
+It offers features like configuration composition from multiple labels, key prefix trimming, automatic resolution of Key Vault references, and many more.
+As an example, this tutorial shows how to use the JavaScript provider in a Node.js app.
 
 ## Prerequisites
 
 - An Azure account with an active subscription. [Create one for free](https://azure.microsoft.com/free/).
 - An App Configuration store. [Create a store](./quickstart-azure-app-configuration-create.md#create-an-app-configuration-store).
 - [LTS versions of Node.js](https://github.com/nodejs/release#release-schedule). For information about installing Node.js either directly on Windows or using the Windows Subsystem for Linux (WSL), see [Get started with Node.js](/windows/dev-environment/javascript/nodejs-overview)
