 # Mapbox in Objective-C
 
-Mapbox iOS SDK is built entirely in Swift and not fully compatible with Objective-C.
+Mapbox is a well-known service which provide mapping and navigation services across platforms from iOS/Android and Web.
+Their SDK for iOS was migrated to Swift entirely and no longer fully compatible with Objective-C, if not say very little.
 
-This library is a part of a QuickStart to work with Mapbox in Objective-C.
-It provides convenient methods to intialize Mapview instance.
+This library is to provide Objective-C compabatible APIs to work with Mapbox fully in Objective-C and other cross platform frameworks like Xamarin.
+This repo is built as an input for the libaray [Xamarin.iOS for Mapbox.iOS](https://github.com/tuyen-vuduc/mapbox-ios-binding.git).
