+# Add React With Webpacker To A New Rails App
+
+[Webpacker](https://github.com/rails/webpacker) makes it easy to manage
+app-like JavaScript in the context of a Rails app. React is a great
+candidate for this kind of webpack-powered JavaScript processing pipeline.
+
+To set up a new Rails project with Webpack and React wired up, add the
+`--webpack=react` flag:
+
+```bash
+$ rails new rails-react-app --webpack=react
+```
+
+As part of the generated app, you will get a `app/javascript/packs`
+directory with a `hello_react.jsx` file that has a really basic React
+component.
