-[Thunk middleware](https://github.com/gaearon/redux-thunk) isn’t the only way to orchestrate asynchronous actions in Redux. You can use [redux-promise](https://github.com/acdlite/redux-promise) or [redux-promise-middleware](https://github.com/pburtchaell/redux-promise-middleware) to dispatch Promises instead of functions. You can dispatch Observables with [redux-rx](https://github.com/acdlite/redux-rx). You can even write a custom middleware to describe calls to your API, like the [real world example](../introduction/Examples.md#real-world) does. It is up to you to try a few options, choose a convention you like, and follow it, whether with, or without the middleware.
