+Add permissions to manifest for android and info.plist for ios (xcode >=8). See notes below for more details.
+
 ```js
 const Permissions = require('react-native-permissions');
 
       })
 ```
 
+With Xcode 8, you now need to add usage descriptions for each permission you will request. Open Xcode > Info.plist > Add a key (starting with "Privacy - ...") with your kit specific permission.
+
+Example:
+If you need Contacts permission you have to add the key "Privacy - Contacts Usage Description".
