## **FastAPI** 애플리케이션 마운트 { #mounting-a-fastapi-application }

"마운트"란 완전히 "독립적인" 애플리케이션을 특정 경로에 추가하고, 그 하위 애플리케이션에 선언된 _경로 처리_로 해당 경로 아래의 모든 것을 처리하도록 하는 것을 의미합니다.

### 최상위 애플리케이션 { #top-level-application }

먼저, 메인 최상위 **FastAPI** 애플리케이션과 그 *경로 처리*를 생성합니다:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 하위 애플리케이션 { #sub-application }

그 다음, 하위 애플리케이션과 그 *경로 처리*를 생성합니다.
