+The initializer has been deprecated and will be removed in version 3.0.0. This is due to the fact that `ember-data >= 4.12` will no longer allow to `reopen` the `Store`. To remove the deprecation message you need to use the utility functions provided by the addon:
+
+```javascript
+import { importData, exportData } from 'ember-local-storage/helpers/import-export';

+See the [Export & Import example](#export--import). When you are done you need to set `loadInitializer` to `false`:

 Using `legacyKey` has been deprecated and will be removed in version 2.0.0. You should migrate your key to the new format. For `storageFor('settings')` that would be `storage:settings`.
