Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).

Um "decorador" pega a função abaixo e faz algo com ela.

Em nosso caso, este decorador informa ao **FastAPI** que a função abaixo corresponde ao **path** `/` com uma **operação** `get`.

É o "**decorador de operação de rota**".

Você também pode usar as outras operações:

* `@app.post()`
