 ## Modal Context -- ABKFeedViewControllerModalContext
 
 - Used to present the view controller in a modal view, with a navigation bar on top and a Done button on the right side of the bar
-- Set the modal's title via the `navigationBarTitle` property
+- Set the modal's title via the embedded `ABKNewsFeedTableViewController` instance's `navigationItem`'s `title` property
 - If a delegate __is NOT set__ the Done button will dismiss the modal view
 - If a delegate __is set__ the Done button will call the delegate, and the delegate itself will be responsible for dismissing the view
