+Many React Native developers aks this question:
+
+> How can I update my Ignite boilerplate with the latest changes from the Ignite boilerplate?
+
+We follow the same technique as [React Native Upgrade Helper](https://react-native-community.github.io/upgrade-helper/), basically it's a [diff between 2 versions](https://github.com/react-native-community/rn-diff-purge) you can apply manually.
+
+Thanks to Niclas Söderström, we can use the [ignite-diff-purge](https://github.com/nirre7/ignite-diff-purge) tool to update your Ignited app.
+
+## Usage
+
+1. Got to [`ignite-diff-purge` website](https://nirre7.github.io/ignite-diff-purge/)

+3. Work through the changes and apply them to your project
