+
+AWS SPIFFE Workload Helper is a light-weight tool intended to assist in
+providing a workload with credentials for AWS using its SPIFFE identity.
+
+Currently, the helper only supports authenticating to AWS using an X.509 SVID
+via [AWS Roles Anywhere](https://docs.aws.amazon.com/rolesanywhere/latest/userguide/introduction.html).
+It provides a more native experience when using SPIFFE identities compared to
+the [`rolesanywhere-credential-helper`](https://github.com/aws/rolesanywhere-credential-helper)
+released by AWS.
+
