-2. If you used RNPM to install/link the CodePush plugin, there are two additional changes you'll need to make due to the fact that RNPM makes some assumptions about 3rd party modules that we don't currently support. If you're not using RNPM then simply skip to step #3:
-
-    ```java
-    ...
-    // 1. Remove the following import statement
-    import com.microsoft.codepush.react.CodePushReactPackage;
-    ...
-    public class MainActivity extends ReactActivity {
