```Python
router.include_router(other_router)
```

/// info

`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.

/// note | Technical Details

/// info | Información

`users.router` contiene el `APIRouter` dentro del archivo `app/routers/users.py`.

Y `items.router` contiene el `APIRouter` dentro del archivo `app/routers/items.py`.

///

Con `app.include_router()` podemos agregar cada `APIRouter` a la aplicación principal de `FastAPI`.

Incluirá todas las rutas de ese router como parte de ella.

/// note | Detalles Técnicos

`users.router` contém o `APIRouter` dentro do arquivo `app/routers/users.py`.

Und `items.router` enthält den `APIRouter` in der Datei `app/routers/items.py`.

///

Mit `app.include_router()` können wir jeden `APIRouter` zur Hauptanwendung `FastAPI` hinzufügen.

Es wird alle Routen von diesem Router als Teil von dieser inkludieren.

/// note | Technische Details

```

/// info | Примечание

`users.router` содержит `APIRouter` из файла `app/routers/users.py`.

А `items.router` содержит `APIRouter` из файла `app/routers/items.py`.

///

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

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

That means that, for example, to apply authentication to all the *path operations* in a router it would end up being done in a different file, instead of keeping related logic together.
