-- LocalStack Pro with the [`localstack` CLI](https://docs.localstack.cloud/getting-started/installation/#localstack-cli).
+- A valid [LocalStack for AWS license](https://localstack.cloud/pricing). Your license provides a [`LOCALSTACK_AUTH_TOKEN`](https://docs.localstack.cloud/getting-started/auth-token/) to activate LocalStack.
