-## Local examples
-
-The repository includes **[`examples/`](examples/README.md)** with **Docker Compose** for MinIO object storage and LocalStack's KMS API. Rails sample apps are kept local and ignored by git; use `examples/rails_minio/` as a scratch path if you generate one for manual testing.
-
 ## Rails / Active Storage setup
 
 Use this path when you want Rails Active Storage to encrypt attachments automatically.
