 # Configuring your test app to use your local fork
+You can test the `react-on-rails` gem using your own external test app or the gem's internal `spec/dummy` app. The `spec/dummy` app is an example of the various setup techniques you can use with the gem.

 ### Starting the Dummy App
-To run the test app, it's **CRITICAL** to not just run `rails s`. You have to run `foreman start`. If you don't do this, then `webpack` will not generate a new bundle, and you will be seriously confused when you change JavaScript and the app does not change. If you change the webpack configs, then you need to restart foreman. If you change the JS code for react-on-rails, you need to run `yarn run build`. Since the react-on-rails package should be sym linked, you don't have to `yarn react-on-rails` after every change.

 ### RSpec Testing
 Run `rake` for testing the gem and `spec/dummy`. Otherwise, the `rspec` command only works for testing within the sample apps, like `spec/dummy`.
