 #### Basic Usage
 Basic usage involves adding `persistReducer` and `persistStore` to your setup. **IMPORTANT** Every app needs to decide how many levels of state they want to "merge". The default is 1 level. Please read through the [state reconciler docs](#state-reconciler) for more information.

 If you are using react, wrap your root component with [PersistGate](./docs/PersistGate.md). This delays the rendering of your app's UI until your persisted state has been retrieved and saved to redux. **NOTE** the `PersistGate` loading prop can be null, or any react instance, e.g. `loading={<Loading />}`
 
 ```js
 import { PersistGate } from 'redux-persist/integration/react'
+import { store, persistor } from './app/store'
 
-// ... normal setup, create store and persistor, import components etc.
