Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[2,15:21] *}

### Modify the OpenAPI schema { #modify-the-openapi-schema }

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[22:24] *}
