   ## Application Default Credentials
-  This library provides an implementation of [Application Default Credentials](https://cloud.google.com/docs/authentication/getting-started) for Node.js. The [Application Default Credentials](https://cloud.google.com/docs/authentication/getting-started) provide a simple way to get authorization credentials for use in calling Google APIs.
 
-  They are best suited for cases when the call needs to have the same identity and authorization level for the application independent of the user. This is the recommended approach to authorize calls to Cloud APIs, particularly when you're building an application that uses Google Cloud Platform.
+  This library provides an implementation of [Application Default Credentials (ADC)](https://cloud.google.com/docs/authentication/application-default-credentials) for Node.js. ADC provides a simple way to get credentials for use in calling Google APIs. How you [set up ADC](https://cloud.google.com/docs/authentication/provide-credentials-adc) depends on the environment where your code is running.
 
-  Application Default Credentials also support workload identity federation to access Google Cloud resources from non-Google Cloud platforms including Amazon Web Services (AWS), Microsoft Azure or any identity provider that supports OpenID Connect (OIDC). Workload identity federation is recommended for non-Google Cloud environments as it avoids the need to download, manage and store service account private keys locally, see: [Workload Identity Federation](#workload-identity-federation).

-  #### Download your Service Account Credentials JSON file
-
-  To use Application Default Credentials, You first need to download a set of JSON credentials for your project. Go to **APIs & Auth** > **Credentials** in the [Google Developers Console](https://console.cloud.google.com/) and select **Service account** from the **Add credentials** dropdown.

-  > This file is your *only copy* of these credentials. It should never be

-
-  Once downloaded, store the path to this file in the `GOOGLE_APPLICATION_CREDENTIALS` environment variable.
