 This basic configuration creates an [StsAssumeRoleCredentialsProvider][sts-assume-provider] with an ARN and session name.
 
+The providers generated by this config property will be [AWS SDK v2 AwsCredentialsProviders][aws-credentials-provider].
+These differ from the SDK v1 AWSCredentialsProviders in a number of ways. See [Credentials Provider Changes][credentials-provider-changes].
+
 While functional, this configuration is limited.
 For example, this configuration cannot set a regional endpoint (e.g., VPC use case).
