+    CodePush depends on an internal copy of the `SSZipArchive` library, so if your project already includes that (either directly or via a transitive dependency), then you can install a version of CodePush which excludes it by using the following subspec:
+    
+    ```ruby
+    pod 'CodePush', :path => './node_modules/react-native-code-push', :subspecs => ['NoZip']

 2. Run `pod install`
 
 *NOTE: The CodePush `.podspec` depends on the `React` pod, and so in order to ensure that it can correctly use the version of React Native that your app is built with, please make sure to define the `React` dependency in your app's `Podfile` as explained [here](http://facebook.github.io/react-native/docs/embedded-app-ios.html#install-react-native-using-cocoapods).*
