+`react-native-svg` is built to provide a SVG interface to react native on both iOS and Android
 
 #### Features
 
 1. Supports most of SVG elements and properties(Rect, Circle, Line, Polyline, Polygon, G ...).
-2. 100% based on ReactNative`s ART library
-3. Easy to convert SVG code into ReactNative code.
+2. Easy to convert SVG code into ReactNative code.

-![example](./screenShoots/art-svg.gif)
 
 #### Install
 
-`npm install react-native-art-svg`
+```
+npm install react-native-svg --save
+rnpm link react-native-svg
+```
 
-##### On iOS we should add import `ART` library into your project
-
-To add ART.xcodeproj find the file located in react-native/Libraries/ART/ART.xcodeproj and just drag it over to the Libraries section in XCode. That should look like so
-
-![Add ART.xcodeproj to Libraries](./screenShoots/addXcodeproj.png)
-
-Next we’ll link the binary.
-
-With the root project selected on the left, select `Build Phases` from the center view. There will be a section called “Link Binary With Libraries”, expand it, press the + and select `libART.a`
-
-Like so
