+### Development 
+
 If you want to build from source and/or contribute to development of the project, run `make iproj`, which will create and open an Xcode project which can build the entire library from source as well as an Objective-C test app. If you don't have an Apple Developer account, change the destination from "My Mac" to a simulator such as "iPhone 6" before you run and build the app.
 
 You can run `make itest` to run the included integration tests. Requires `gem install xcpretty`. If you want to run the tests in Xcode instead, first `make ipackage` to create a local static library version, then open `test/ios/ios-tests.xcodeproj`, and lastly `Command + U` on the `Mapbox GL Tests` application target.
