+    The smoke_sdk scenario deploys a Vault cluster and runs a comprehensive suite of blackbox SDK tests
+    instead of enos-based verification. This scenario validates core Vault functionality including leader election,
+    secrets engines, UI assets, replication status, and backend-specific features using the blackbox SDK.
+
+    # How to run this scenario
+
+    For general instructions on running a scenario, refer to the Enos docs: https://eng-handbook.hashicorp.services/internal-tools/enos/running-a-scenario/
+    For troubleshooting tips and common errors, see https://eng-handbook.hashicorp.services/internal-tools/enos/troubleshooting/.
+
+    Variables required for all scenario variants:
+      - aws_ssh_private_key_path (more info about AWS SSH keypairs: https://eng-handbook.hashicorp.services/internal-tools/enos/getting-started/#set-your-aws-key-pair-name-and-private-key)
+      - aws_ssh_keypair_name
+      - vault_build_date*
+      - vault_product_version

+    https://eng-handbook.hashicorp.services/internal-tools/enos/troubleshooting/#execution-error-expected-vs-got-for-vault-versioneditionrevisionbuild-date.

+      distro. See supported distros and default versions in the distro_version_<distro>
