-// Amazon Simple Notification Service (Amazon SNS) is a web service that enables
-// you to build distributed web-enabled applications. Applications can use Amazon
-// SNS to easily push real-time notification messages to interested subscribers
-// over multiple delivery protocols. For more information about this product
-// see http://aws.amazon.com/sns (http://aws.amazon.com/sns/). For detailed
-// information about Amazon SNS features and their associated API calls, see
-// the Amazon SNS Developer Guide (http://docs.aws.amazon.com/sns/latest/dg/).
+// SNS provides the API operation methods for making requests to
+// Amazon Simple Notification Service. See this package's package overview docs
+// for details on the service.
 //
-// We also provide SDKs that enable you to access Amazon SNS from your preferred
-// programming language. The SDKs contain functionality that automatically takes
-// care of tasks such as: cryptographically signing your service requests, retrying
-// requests, and handling error responses. For a list of available SDKs, go
-// to Tools for Amazon Web Services (http://aws.amazon.com/tools/).
-// The service client's operations are safe to be used concurrently.
-// It is not safe to mutate any of the client's properties though.
