'StaticFiles'를 사용하여 디렉토리에서 정적 파일을 자동으로 제공할 수 있습니다.

## `StaticFiles` 사용

* `StaticFiles` 임포트합니다.
* 특정 경로에 `StaticFiles()` 인스턴스를 "마운트" 합니다.

{* ../../docs_src/static_files/tutorial001.py hl[2,6] *}

/// note | 기술적 세부사항

`from starlette.staticfiles import StaticFiles` 를 사용할 수도 있습니다.

**FastAPI**는 단지 개발자인, 당신에게 편의를 제공하기 위해 `fastapi.static files` 와 동일한 `starlett.static files`를 제공합니다. 하지만 사실 이것은 Starlett에서 직접 온 것입니다.
