+// Package ssocreds provides a credential provider for retrieving temporary AWS credentials using an SSO access token.
+//
+// IMPORTANT: The provider in this package does not initiate or perform the AWS SSO login flow. The SDK provider
+// expects that you have already performed the SSO login flow using AWS CLI using the "aws sso login" command, or by
+// some other mechanism. The provider must find a valid non-expired access token for the AWS SSO user portal URL in
+// ~/.aws/sso/cache. If a cached token is not found, it is expired, or the file is malformed an error will be returned.
+//
+// Loading AWS SSO credentials with the AWS shared configuration file
+//
+// You can use configure AWS SSO credentials from the AWS shared configuration file by
+// providing the specifying the required keys in the profile:
+//
+//  sso_account_id
+//  sso_region
+//  sso_role_name
+//  sso_start_url
+//
+// For example, the following defines a profile "devsso" and specifies the AWS SSO parameters that defines the target
+// account, role, sign-on portal, and the region where the user portal is located. Note: all SSO arguments must be
+// provided, or an error will be returned.
+//
+//  [profile devsso]
+//  sso_start_url = https://my-sso-portal.awsapps.com/start
+//  sso_role_name = SSOReadOnlyRole
+//  sso_region = us-east-1
+//  sso_account_id = 123456789012
+//
+// Using the config module, you can load the AWS SDK shared configuration, and specify that this profile be used to
+// retrieve credentials. For example:
+//
+//  sess, err := session.NewSessionWithOptions(session.Options{
+//      SharedConfigState: session.SharedConfigEnable,
+//      Profile:           "devsso",
