+## Releasing asset updates - iOS
+
+If you are using the new React Native [assets system](https://facebook.github.io/react-native/docs/images.html#content), as opposed to loading your images from the network and/or platform-specific mechanisms (e.g. iOS asset catalogs), then you can't simply pass your jsbundle to CodePush as demonstrated above. You need to provide your images as well. To do this, simply use the following workflow:
+
+1. When calling `react-native bundle`, specify that your assets and JS bundle go into a new "release" folder (you can call this anything, but it shouldn't contain any other files). For example:
+
+    ```
+    react-native bundle \
+    --platform ios \
+    --entry-file index.ios.js \
+    --bundle-output ./release/main.jsbundle \
+    --assets-dest ./release
+    ```
+
+2. Execute `code-push release`, passing the path to the directory you used in #1 as the "package" parameter (e.g. `code-push release Foo ./release 1.0.0`). The code-push CLI will automatically handle zipping up the contents for you, so don't worry about handling that yourself.
+
+Additionally, the CodePush client supports differential updates, so even though you are releasing your JS bundle and assets on every update, your end-users will only actually download the files they need. The service handles this automatically so that you can focus on creating awesome apps and we can worry about optimizing end-user downloads.
+
+*Note: Releasing assets via CodePush is currently only supported on iOS, and requires that you're using React Native v0.15.0+.*
