How do I setup the redux-promise middleware, specifically what import and configurations statements do I need? 

<https://github.com/acdlite/redux-promise>

The readme states `import promiseMiddleware from 'redux-promise'`, and I'm assuming I have to import createAction as well.. but is that all I need, or do I need to configure or add it to the redux configuration somehow?

Is this all I need to do?

actions/SampleActions.js

```
import promiseMiddleware from 'redux-promise';
import { createAction } from 'redux-actions';
import { WebAPI } from '../utils/WebAPI';

export const getThing = createAction('GET_THING', WebAPI.getThing);
export const createThing = createAction('POST_THING', WebAPI.createThing);

```
