Uma vez que você acessar <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>, verá que está usando seu logo personalizado (neste exemplo, o logo do **FastAPI**):

### Tags com Enums

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:
