-//
-// # Considerations for Using This Guide
-//
-// Before you begin using this guide, we recommend that you first review the
-// following important information about how the Amazon Web Services SSO OIDC
-// service works.
-//
-//   - The Amazon Web Services SSO OIDC service currently implements only the
-//     portions of the OAuth 2.0 Device Authorization Grant standard (https://tools.ietf.org/html/rfc8628
-//     (https://tools.ietf.org/html/rfc8628)) that are necessary to enable single
-//     sign-on authentication with the AWS CLI. Support for other OIDC flows
-//     frequently needed for native applications, such as Authorization Code
-//     Flow (+ PKCE), will be addressed in future releases.
-//
-//   - The service emits only OIDC access tokens, such that obtaining a new
-//     token (For example, token refresh) requires explicit user re-authentication.
-//
-//   - The access tokens provided by this service grant access to all AWS account
-//     entitlements assigned to an Amazon Web Services SSO user, not just a particular
-//     application.
-//
-//   - The documentation in this guide does not describe the mechanism to convert
-//     the access token into AWS Auth (“sigv4”) credentials for use with
-//     IAM-protected AWS service endpoints. For more information, see GetRoleCredentials
-//     (https://docs.aws.amazon.com/singlesignon/latest/PortalAPIReference/API_GetRoleCredentials.html)
-//     in the Amazon Web Services SSO Portal API Reference Guide.
-//
-// For general information about Amazon Web Services SSO, see What is Amazon
-// Web Services SSO? (https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html)
-// in the Amazon Web Services SSO User Guide.
+// AWS Single Sign-On (SSO) OpenID Connect (OIDC) is a web service that enables
+// a client (such as AWS CLI or a native application) to register with AWS SSO.
+// The service also enables the client to fetch the user’s access token upon
+// successful authentication and authorization with AWS SSO. This service conforms
+// with the OAuth 2.0 based implementation of the device authorization grant
+// standard (https://tools.ietf.org/html/rfc8628 (https://tools.ietf.org/html/rfc8628)).
+//
+// For general information about AWS SSO, see What is AWS Single Sign-On? (https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html)
+// in the AWS SSO User Guide.
+//
+// This API reference guide describes the AWS SSO OIDC operations that you can
+// call programatically and includes detailed information on data types and
+// errors.
+//
+// AWS provides SDKs that consist of libraries and sample code for various programming
+// languages and platforms such as Java, Ruby, .Net, iOS, and Android. The SDKs
+// provide a convenient way to create programmatic access to AWS SSO and other
+// AWS services. For more information about the AWS SDKs, including how to download
+// and install them, see Tools for Amazon Web Services (http://aws.amazon.com/tools/).
