## Documentation Summary and Description - OpenAPI { #documentation-summary-and-description-openapi }

To add a summary and description to your *path operations*, and show them in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Summary and Description](../tutorial/path-operation-configuration.md#summary-and-description){.internal-link target=_blank}.

| `summary` | `str` | A short summary of the API. <small>Available since OpenAPI 3.1.0, FastAPI 0.99.0.</small> |
