 //
-// Using workload identity federation, your application can access Google Cloud
-// resources from Amazon Web Services (AWS), Microsoft Azure or any identity
-// provider that supports OpenID Connect (OIDC) or SAML 2.0.
-// Traditionally, applications running outside Google Cloud have used service
-// account keys to access Google Cloud resources. Using identity federation,
-// you can allow your workload to impersonate a service account.
-// This lets you access Google Cloud resources directly, eliminating the
-// maintenance and security burden associated with service account keys.
-//
-// Follow the detailed instructions on how to configure Workload Identity Federation
-// in various platforms:
-//
-//	Amazon Web Services (AWS): https://cloud.google.com/iam/docs/workload-identity-federation-with-other-clouds#aws
-//	Microsoft Azure: https://cloud.google.com/iam/docs/workload-identity-federation-with-other-clouds#azure

-//	SAML 2.0 identity provider: https://cloud.google.com/iam/docs/workload-identity-federation-with-other-providers#saml
-//
-// For OIDC and SAML providers, the library can retrieve tokens in three ways:
-// from a local file location (file-sourced credentials), from a server
-// (URL-sourced credentials), or from a local executable (executable-sourced
-// credentials).
-// For file-sourced credentials, a background process needs to be continuously
-// refreshing the file location with a new OIDC/SAML token prior to expiration.
-// For tokens with one hour lifetimes, the token needs to be updated in the file
-// every hour. The token can be stored directly as plain text or in JSON format.
-// For URL-sourced credentials, a local server needs to host a GET endpoint to
-// return the OIDC/SAML token. The response can be in plain text or JSON.
-// Additional required request headers can also be specified.
-// For executable-sourced credentials, an application needs to be available to
-// output the OIDC/SAML token and other information in a JSON format.
-// For more information on how these work (and how to implement
-// executable-sourced credentials), please check out:
-// https://cloud.google.com/iam/docs/workload-identity-federation-with-other-providers#create_a_credential_configuration
-//
-// Note that this library does not perform any validation on the token_url, token_info_url,
-// or service_account_impersonation_url fields of the credential configuration.
-// It is not recommended to use a credential configuration that you did not generate with
-// the gcloud CLI unless you verify that the URL fields point to a googleapis.com domain.

-// # Workforce Identity Federation
-//
-// Workforce identity federation lets you use an external identity provider (IdP) to
-// authenticate and authorize a workforce—a group of users, such as employees, partners,
-// and contractors—using IAM, so that the users can access Google Cloud services.
-// Workforce identity federation extends Google Cloud's identity capabilities to support

-//
-// With workforce identity federation, your workforce can access Google Cloud resources

+
+Using workload identity federation, your application can access Google Cloud
+resources from Amazon Web Services (AWS), Microsoft Azure or any identity
+provider that supports OpenID Connect (OIDC) or SAML 2.0.
+Traditionally, applications running outside Google Cloud have used service
+account keys to access Google Cloud resources. Using identity federation,
+you can allow your workload to impersonate a service account.
+This lets you access Google Cloud resources directly, eliminating the
+maintenance and security burden associated with service account keys.
+
+Follow the detailed instructions on how to configure Workload Identity Federation
+in various platforms:
+
+Amazon Web Services (AWS): https://cloud.google.com/iam/docs/workload-identity-federation-with-other-clouds#aws
+Microsoft Azure: https://cloud.google.com/iam/docs/workload-identity-federation-with-other-clouds#azure
+OIDC identity provider: https://cloud.google.com/iam/docs/workload-identity-federation-with-other-providers#oidc
+SAML 2.0 identity provider: https://cloud.google.com/iam/docs/workload-identity-federation-with-other-providers#saml
+
+For OIDC and SAML providers, the library can retrieve tokens in fours ways:
+from a local file location (file-sourced credentials), from a server
+(URL-sourced credentials), from a local executable (executable-sourced
+credentials), or from a user defined function that returns an OIDC or SAML token.
+For file-sourced credentials, a background process needs to be continuously
+refreshing the file location with a new OIDC/SAML token prior to expiration.
+For tokens with one hour lifetimes, the token needs to be updated in the file
+every hour. The token can be stored directly as plain text or in JSON format.
+For URL-sourced credentials, a local server needs to host a GET endpoint to
+return the OIDC/SAML token. The response can be in plain text or JSON.
+Additional required request headers can also be specified.
+For executable-sourced credentials, an application needs to be available to
+output the OIDC/SAML token and other information in a JSON format.
+For more information on how these work (and how to implement
+executable-sourced credentials), please check out:
+https://cloud.google.com/iam/docs/workload-identity-federation-with-other-providers#create_a_credential_configuration
+
+To use a custom function to supply the token, define a struct that implements the [SubjectTokenSupplier] interface for OIDC/SAML providers,
+or one that implements [AwsSecurityCredentialsSupplier] for AWS providers. This can then be used when building a [Config].
+The [golang.org/x/oauth2.TokenSource] created from the config using [NewTokenSource] can then be used to access Google
+Cloud resources. For instance, you can create a new client from the
+[cloud.google.com/go/storage] package and pass in option.WithTokenSource(yourTokenSource))
+
+Note that this library does not perform any validation on the token_url, token_info_url,
+or service_account_impersonation_url fields of the credential configuration.
+It is not recommended to use a credential configuration that you did not generate with
+the gcloud CLI unless you verify that the URL fields point to a googleapis.com domain.
+
+# Workforce Identity Federation
+
+Workforce identity federation lets you use an external identity provider (IdP) to
+authenticate and authorize a workforce—a group of users, such as employees, partners,
+and contractors—using IAM, so that the users can access Google Cloud services.
+Workforce identity federation extends Google Cloud's identity capabilities to support
+syncless, attribute-based single sign on.
+
+With workforce identity federation, your workforce can access Google Cloud resources
+using an external identity provider (IdP) that supports OpenID Connect (OIDC) or
+SAML 2.0 such as Azure Active Directory (Azure AD), Active Directory Federation
+Services (AD FS), Okta, and others.
+
+Follow the detailed instructions on how to configure Workload Identity Federation
+in various platforms:
+
+Azure AD: https://cloud.google.com/iam/docs/workforce-sign-in-azure-ad
+Okta: https://cloud.google.com/iam/docs/workforce-sign-in-okta
+OIDC identity provider: https://cloud.google.com/iam/docs/configuring-workforce-identity-federation#oidc
+SAML 2.0 identity provider: https://cloud.google.com/iam/docs/configuring-workforce-identity-federation#saml
+
+For workforce identity federation, the library can retrieve tokens in four ways:
+from a local file location (file-sourced credentials), from a server
+(URL-sourced credentials), from a local executable (executable-sourced
+credentials), or from a user supplied function that returns an OIDC or SAML token.
+For file-sourced credentials, a background process needs to be continuously
+refreshing the file location with a new OIDC/SAML token prior to expiration.
+For tokens with one hour lifetimes, the token needs to be updated in the file
+every hour. The token can be stored directly as plain text or in JSON format.
+For URL-sourced credentials, a local server needs to host a GET endpoint to
+return the OIDC/SAML token. The response can be in plain text or JSON.
+Additional required request headers can also be specified.
+For executable-sourced credentials, an application needs to be available to
+output the OIDC/SAML token and other information in a JSON format.
+For more information on how these work (and how to implement
+executable-sourced credentials), please check out:
+https://cloud.google.com/iam/docs/workforce-obtaining-short-lived-credentials#generate_a_configuration_file_for_non-interactive_sign-in
+
+To use a custom function to supply the token, define a struct that implements the [SubjectTokenSupplier] interface for OIDC/SAML providers.
+This can then be used when building a [Config].
+The [golang.org/x/oauth2.TokenSource] created from the config using [NewTokenSource] can then be used access Google
+Cloud resources. For instance, you can create a new client from the
+[cloud.google.com/go/storage] package and pass in option.WithTokenSource(yourTokenSource))
