### Criar Metadados para tags { #create-metadata-for-tags }

Vamos tentar isso em um exemplo com tags para `users` e `items`.

Crie metadados para suas tags e passe-os para o parâmetro `openapi_tags`:

### 2 단계: `FastAPI` "인스턴스" 생성 { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

여기에서 `app` 변수는 `FastAPI` 클래스의 "인스턴스"가 됩니다.

이것은 여러분의 모든 API를 생성하기 위한 상호작용의 주요 지점이 될 것입니다.

### 3 단계: *경로 처리* 생성 { #step-3-create-a-path-operation }

#### 경로 { #path }

여기서 "경로"는 첫 번째 `/`부터 시작하는 URL의 뒷부분을 의미합니다.
