 Copy [`.env.example`](.env.example) to `.env` for local development. `RedisConfig.from_env()` and `MinioConfig.from_env()` load `.env` automatically when resolving configuration from the environment.
 
+For production, it is recommended to leave `MINIO_CREATE_BUCKET_IF_MISSING` unset so that `connect()` fails fast if the expected bucket is missing. For local development, you will often want `MINIO_SECURE=false` and `MINIO_CREATE_BUCKET_IF_MISSING=true`.

 ## Configuration injection
 
 Adapters accept optional `config` and `client` keyword arguments for explicit setup and testing:
