`users.router` contains the `APIRouter` inside of the file `app/routers/users.py`.

And `items.router` contains the `APIRouter` inside of the file `app/routers/items.py`.

With `app.include_router()` we can add each `APIRouter` to the main `FastAPI` application.

It will include all the routes from that router as part of it.

С помощью `app.include_router()` мы можем добавить каждый из маршрутизаторов (`APIRouter`) в основное приложение `FastAPI`.

Он подключит все маршруты заданного маршрутизатора к нашему приложению.

/// note | Технические детали

La dependencia original podría ser utilizada en una *path operation function*, un *path operation decorator* (cuando no usas el valor de retorno), una llamada a `.include_router()`, etc.

FastAPI todavía podrá sobrescribirla.

///

Entonces puedes restablecer las dependencias sobreescritas configurando `app.dependency_overrides` para que sea un `dict` vacío:

```Python

The original dependency could be used in a *path operation function*, a *path operation decorator* (when you don't use the return value), a `.include_router()` call, etc.

FastAPI will still be able to override it.

///

Then you can reset your overrides (remove them) by setting `app.dependency_overrides` to be an empty `dict`:

```Python

        await self.app(scope, wrapper, send)
