Podemos declarar todo eso sin tener que modificar el `APIRouter` original pasando esos parámetros a `app.include_router()`:

```Python hl_lines="14-17" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

Podemos declarar tudo isso sem precisar modificar o `APIRouter` original passando esses parâmetros para `app.include_router()`:

```Python hl_lines="14-17" title="app/main.py"

Dessa forma, o `APIRouter` original permanecerá inalterado, para que possamos compartilhar o mesmo arquivo `app/internal/admin.py` com outros projetos na organização.
