+You can receive actions in your reducers.
+
+This allows you to have loading on a per reducer basis separated across the application for stored data instead of having the full application wait for the data to be loaded.
+
+The package exports a function that makes it easier for you to set up a case in the reducer, by generating an action name that matches the one that the package uses under the hood.
+
+The code below will apply the saved state to your current state:
 
 ```js
-case "@ReduxPM/LoadSubscriptionOrders": {
- return {
- ...state,
+import { getPersistMachineAction } from 'redux-persist-machine'
+
+case getPersistMachineAction("load.subscriptionOrders"): {
+ return {
+ ...state,
  ...action.payload,
  }
 }
 ```
 
-This allows you to have loading on a per reducer basis separated across the application for stored data instead of having the full application wait for the data to be loaded.
+Of course, you can also define your own custom action name. This custom action name has to be passed oon the `action` property of the reducer in the structure object.
 
 The middleware runs: `action.payload = { ...storedData, ...action.payload };` to add the saved data to the payload when the `@ReduxPM/LoadActions` is triggered. You can also pass additional data in your payload to add context to your `@ReduxPM/LoadActions` for complex conditional consummation of the loaded data in your reducers.

 Starts the persist middleware. You should run this immediately after creating your store.

 const persistMiddleware = createPersistMiddleware(structure, saveState, loadState)
 persistMiddleware.run(store)

+
+Generates an action name based on the provided key. You can use this function to set the case in your reducer to handle the data loading.

+```js
+case getPersistMachineAction("load.user.orders"): {
