 Permission type `bluetooth` represents the status of the `CBPeripheralManager`. Don't use this if only need `CBCentralManager`
 
 Permission type `location` accepts a second parameter for `requestPermission` and `getPermissionStatus`;  the second parameter is a string, either `always` or `whenInUse`(default).
 If you need Contacts permission you have to add the key "Privacy - Contacts Usage Description".

+## AppStore submission disclaimer
 
-##Troubleshooting
+If you need to submit you application to the AppStore, you need to add to your `Info.plist` all `*UsageDescription` keys with a string value explaining to the user how the app uses this data. **Even if you don't use them**.
+
+So before submitting your app to the `AppStore`, make sure that in your `Info.plist` you have the following keys:
+
+```
+
+<key>NSBluetoothPeripheralUsageDescription</key>
+<string>Some description</string>
+<key>NSCalendarsUsageDescription</key>
+<string>Some description</string>
+<key>NSCameraUsageDescription</key>
+<string>Some description</string>
+<key>NSLocationWhenInUseUsageDescription</key>
+<string>Some description</string>
+<key>NSPhotoLibraryUsageDescription</key>
+<string>Some description</string>
+
+```
+
+This is required because during the phase of `processing` in the `AppStore` submission, the system detects that you app contains code to request the permission `X` but don't have the `UsageDescription` key and rejects the build.
+
+> Please note that it will only be shown to the users the usage descriptions of the permissions you really require in your app.
+
+You can find more informations about this issue in #46.

 #### Q: Android - `undefined is not a object (evaluating 'RNPermissions.requestPermissions')`
 A: `rnpm` may not have linked correctly. Follow the manual linking steps and make sure the library is linked
