# FastAPI CLI

**FastAPI CLI**는 FastAPI 애플리케이션을 실행하고, 프로젝트를 관리하는 등 다양한 작업을 수행할 수 있는 커맨드 라인 프로그램입니다.

FastAPI를 설치할 때 (예: `pip install "fastapi[standard]"` 명령어를 사용할 경우), `fastapi-cli`라는 패키지가 포함됩니다. 이 패키지는 터미널에서 사용할 수 있는 `fastapi` 명령어를 제공합니다.

개발용으로 FastAPI 애플리케이션을 실행하려면 다음과 같이 `fastapi dev` 명령어를 사용할 수 있습니다:
