+// As an alternative to using the API, you can use one of the AWS SDKs, which
+// consist of libraries and sample code for various programming languages and
+// platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient
+// way to create programmatic access to STS. For example, the SDKs take care
+// of cryptographically signing requests, managing errors, and retrying requests
+// automatically. For information about the AWS SDKs, including how to download
+// and install them, see the Tools for Amazon Web Services page (http://aws.amazon.com/tools/).
+//
+// For information about setting up signatures and authorization through the
+// API, go to Signing AWS API Requests (http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html)
+// in the AWS General Reference. For general information about the Query API,
+// go to Making Query Requests (http://docs.aws.amazon.com/IAM/latest/UserGuide/IAM_UsingQueryAPI.html)
+// in Using IAM. For information about using security tokens with other AWS
+// products, go to AWS Services That Work with IAM (http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html)
+// in the IAM User Guide.

+// If you're new to AWS and need additional technical information about a specific
+// AWS product, you can find the product's technical documentation at http://aws.amazon.com/documentation/
+// (http://aws.amazon.com/documentation/).
+//
+// Endpoints
+//
+// The AWS Security Token Service (STS) has a default endpoint of https://sts.amazonaws.com
+// that maps to the US East (N. Virginia) region. Additional regions are available
+// and are activated by default. For more information, see Activating and Deactivating
+// AWS STS in an AWS Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html)
+// in the IAM User Guide.
+//
+// For information about STS endpoints, see Regions and Endpoints (http://docs.aws.amazon.com/general/latest/gr/rande.html#sts_region)
+// in the AWS General Reference.
+//
+// Recording API requests
+//
+// STS supports AWS CloudTrail, which is a service that records AWS calls for
+// your AWS account and delivers log files to an Amazon S3 bucket. By using
+// information collected by CloudTrail, you can determine what requests were
+// successfully made to STS, who made the request, when it was made, and so
+// on. To learn more about CloudTrail, including how to turn it on and find
+// your log files, see the AWS CloudTrail User Guide (http://docs.aws.amazon.com/awscloudtrail/latest/userguide/what_is_cloud_trail_top_level.html).
+// The service client's operations are safe to be used concurrently.
+// It is not safe to mutate any of the client's properties though.
+// Please also see https://docs.aws.amazon.com/goto/WebAPI/sts-2011-06-15
