 different depending on the environment you use. Here we provide some basic instruction in how to get
 started with deployment of your project:
 
- * For applications running on Google Cloud Platform (for example, in Google Compute Engine, Google
-   App Engine, Google Kubernetes Engine, and Google Cloud Functions), applications are automatically
-   authenticated using the Metadata Server. For more information, see
-   [About VM Metadata](https://cloud.google.com/compute/docs/metadata/overview)
- * For applications running elsewhere, it is recommended to
-   [create a Service Account](https://cloud.google.com/iam/docs/service-accounts-create) and enable
-   [Workload Identity Federation](https://cloud.google.com/iam/docs/workload-identity-federation).
- * It is also possible to authenticate using
-   [Service Account Keys](https://cloud.google.com/iam/docs/migrate-from-service-account-keys). Set
-   the `GOOGLE_APPLICATION_CREDENTIALS` environment variable pointing to your credentials file.
-
-Authentication is handled by the client once the environment is configured. Once your credentials
-are created You just need to provide the authentication details when creating a client. Generally,
-authentication is accomplished using a Service Account. For more information on obtaining Service
-Account credentials see our
-[Authentication Guide](https://cloud.google.com/docs/authentication/production#manually).
