 ## Azure IotHubClient SDK for JavaScript
 
-This package contains an isomorphic SDK for IotHubClient.
+This package contains an isomorphic SDK (runs both in node.js and in browsers) for IotHubClient.
 
 ### Currently supported environments
 
-- Node.js version 6.x.x or higher
-- Browser JavaScript
+- [LTS versions of Node.js](https://nodejs.org/about/releases/)
+- Latest versions of Safari, Chrome, Edge and Firefox.
 
-### How to Install
+### Prerequisites
 
+You must have an [Azure subscription](https://azure.microsoft.com/free/).
+
+### How to install
+
+To use this SDK in your project, you will need to install two packages.
+- `@azure/arm-iothub` that contains the client.
+- `@azure/identity` that provides different mechanisms for the client to authenticate your requests using Azure Active Directory.
+
+Install both packages using the below command:
 ```bash
-npm install @azure/arm-iothub
+npm install --save @azure/arm-iothub @azure/identity
 ```
+> **Note**: You may have used either `@azure/ms-rest-nodeauth` or `@azure/ms-rest-browserauth` in the past. These packages are in maintenance mode receiving critical bug fixes, but no new features.
+If you are on a [Node.js that has LTS status](https://nodejs.org/about/releases/), or are writing a client side browser application, we strongly encourage you to upgrade to `@azure/identity` which uses the latest versions of Azure Active Directory and MSAL APIs and provides more authentication options.
 
 ### How to use
 
-#### nodejs - client creation and list operations as an example written in TypeScript.
+- If you are writing a client side browser application,
+  - Follow the instructions in the section on Authenticating client side browser applications in [Azure Identity examples](https://aka.ms/azsdk/js/identity/examples) to register your application in the Microsoft identity platform and set the right permissions.
+  - Copy the client ID and tenant ID from the Overview section of your app registration in Azure portal and use it in the browser sample below.
+- If you are writing a server side application,
+  - [Select a credential from `@azure/identity` based on the authentication method of your choice](https://aka.ms/azsdk/js/identity/examples)
+  - Complete the set up steps required by the credential if any.
+  - Use the credential you picked in the place of `DefaultAzureCredential` in the Node.js sample below.
 
-##### Install @azure/ms-rest-nodeauth
-
-- Please install minimum version of `"@azure/ms-rest-nodeauth": "^3.0.0"`.
-
-```bash
-npm install @azure/ms-rest-nodeauth@"^3.0.0"
-```
+In the below samples, we pass the credential and the Azure subscription id to instantiate the client.
+Once the client is created, explore the operations on it either in your favorite editor or in our [API reference documentation](https://docs.microsoft.com/javascript/api) to get started.
+#### nodejs - Authentication, client creation, and list operations as an example written in JavaScript.
 
 ##### Sample code
 
-While the below sample uses the interactive login, other authentication options can be found in the [README.md file of @azure/ms-rest-nodeauth](https://www.npmjs.com/package/@azure/ms-rest-nodeauth) package
-
-```typescript
-const msRestNodeAuth = require("@azure/ms-rest-nodeauth");
+```javascript
+const { DefaultAzureCredential } = require("@azure/identity");
 const { IotHubClient } = require("@azure/arm-iothub");
 const subscriptionId = process.env["AZURE_SUBSCRIPTION_ID"];
 
-msRestNodeAuth
-  .interactiveLogin()
-  .then((creds) => {
-    const client = new IotHubClient(creds, subscriptionId);
-    client.operations.list().then((result) => {
-      console.log("The result is:");
-      console.log(result);
-    });
-  })
-  .catch((err) => {
-    console.error(err);
-  });
+// Use `DefaultAzureCredential` or any other credential of your choice based on https://aka.ms/azsdk/js/identity/examples
+// Please note that you can also use credentials from the `@azure/ms-rest-nodeauth` package instead.
+const creds = new DefaultAzureCredential();
+const client = new IotHubClient(creds, subscriptionId);
+client.operations.list().then((result) => {
+  console.log("The result is:");
+  console.log(result);
+}).catch((err) => {
+  console.log("An error occurred:");
+  console.error(err);
+});
 ```
 
-#### browser - Authentication, client creation and list operations as an example written in JavaScript.
-
-##### Install @azure/ms-rest-browserauth
+#### browser - Authentication, client creation, and list operations as an example written in JavaScript.
 
-```bash
-npm install @azure/ms-rest-browserauth
-```
+In browser applications, we recommend using the `InteractiveBrowserCredential` that interactively authenticates using the default system browser.
+  - See [Single-page application: App registration guide](https://docs.microsoft.com/azure/active-directory/develop/scenario-spa-app-registration) to configure your app registration for the browser.
+  - Note down the client Id from the previous step and use it in the browser sample below.
 
 ##### Sample code
 
-See https://github.com/Azure/ms-rest-browserauth to learn how to authenticate to Azure in the browser.
