그다음 `custom_openapi()` 함수 안에서, 동일한 유틸리티 함수를 사용해 OpenAPI 스키마를 생성합니다:

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

### OpenAPI 스키마 수정하기 { #modify-the-openapi-schema }

이제 OpenAPI 스키마의 `info` "object"에 커스텀 `x-logo`를 추가하여 ReDoc 확장을 더할 수 있습니다:

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

### OpenAPI 스키마 캐시하기 { #cache-the-openapi-schema }
