Hi am reading though the documents for the WP for IOS.

it starts with download the project and unzip it, is this referring to my wordpress site or the iOS.zip in the plugin folder ??

Also i have not started this yet obviously, but as you update your wordpress site will it update the app and equally if a member signs up on the app will it automatically update the main site ?
