Now, let's include the `router`s from the submodules `users` and `items`:

{* ../../docs_src/bigger_applications/app_an_py39/main.py hl[10:11] title["app/main.py"] *}

/// 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`.

        this.channelCounter = new AtomicInteger(0);
        this.multiChannelEnabled = false;

        // Schedule periodic health checks
        scheduler.scheduleAtFixedRate(this::performHealthCheck, 10, 10, TimeUnit.SECONDS);

        // Schedule interface discovery
        scheduler.scheduleAtFixedRate(this::discoverInterfaces, 0, 30, TimeUnit.SECONDS);
    }

    /**
