# Advanced Middleware { #advanced-middleware }

In the main tutorial you read how to add [Custom Middleware](../tutorial/middleware.md) to your application.

And then you also read how to handle [CORS with the `CORSMiddleware`](../tutorial/cors.md).

In this section we'll see how to use other middlewares.
