-# Mapbox GL for iOS
-
-Use or edit this project to get access to vector maps (via [Mapbox Vector Tiles](https://www.mapbox.com/blog/vector-tiles)) and dynamic OpenGL-based styling in your iOS apps by using `MGLMapView`. 
-

-
-## Installation
-
-Currently in flux. See the parent `mapbox-gl-native` project `README` for details on building this library yourself. 
-
-Static and dynamic prebuilt binaries are coming back, as is CocoaPods support. 
-
-## Example usage
-
-### Objective-C
-
-```objective-c
-MGLMapView *mapView = [[MGLMapView alloc] initWithFrame:CGRectMake(0, 0, 400, 400)
-                                            accessToken:@"<access token string>"];
-
-[mapView setCenterCoordinate:CLLocationCoordinate2DMake(28.369334, -80.743779) 
-                   zoomLevel:13 
-                    animated:NO];
-
-[mapView useBundledStyleNamed:@"outdoors"];
-
-[self.view addSubview:mapView];
-```
-
-### Swift
-
-```swift
-let mapView = MGLMapView(frame: CGRect(x: 0, y: 0, width: 400, height: 400),
-                         accessToken: "<access token string>")
-
-mapView.setCenterCoordinate(CLLocationCoordinate2D(latitude: 46.049900, longitude: -122.095678),
-        zoomLevel: 12,
-        animated: false)
-
-mapView.useBundledStyleNamed("outdoors")
-
-view.addSubview(mapView)
-```
-
-## Development
-
-If you'd like to contribute to this project, go up to [Mapbox GL native](https://github.com/mapbox/mapbox-gl-native) and clone the project. 
-
-## Testing
-
-Currently in flux and not functioning. 
-
-## Requirements
-
- * iOS 7+
- * a sense of adventure
-
-## Styling
-
-See the [online style reference](https://www.mapbox.com/mapbox-gl-style-spec/) for the latest documentation. Contained within the `MapboxGL.bundle` assets are a couple of starter styles in JSON format. 
-
-The project will eventually get a programmatic styling API as well.
