+This library, ADAL for Node.js, will no longer receive new feature improvements. Instead, use the new library
+[MSAL for Node.js](https://github.com/AzureAD/microsoft-authentication-library-for-js/tree/dev/lib/msal-node).
+
+* If you are starting a new project, you can get started with the
+  [MSAL for Node.js docs](https://github.com/AzureAD/microsoft-authentication-library-for-js/tree/dev/lib/msal-node)
+  for details about the scenarios, usage, and relevant concepts.
+* If your application is using the previous ADAL for Node.js library, you can follow this
+  [migration guide for Node.js apps](https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-node/docs/migration.md).
+* Existing applications relying on ADAL for Node.js will continue to work.

+## Update to MSAL for Node.js now!
+
+[MSAL for Node.js](https://github.com/AzureAD/microsoft-authentication-library-for-js/tree/dev/lib/msal-node) is the new authentication library to be used with the Microsoft identity platform
+
+Building on top of ADAL, MSAL works with the new and Open ID Connect certified Azure AD V2 endpoint and the new social identity solution from Microsoft, Azure AD B2C.
+
+ADAL for Node.js is in maintenance mode and no new features will be added to the ADAL library anymore. All our ongoing efforts will be focused on improving the new [MSAL for Node.js](https://github.com/AzureAD/microsoft-authentication-library-for-js/tree/dev/lib/msal-node). MSAL’s documentation also contains a [migration guide](https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-node/docs/migration.md) which simplifies upgrading from ADAL for Node.js.
