+Example iOS Backend
+====
+
+This is a really simple [Sinatra](http://www.sinatrarb.com/) webapp that you can use to test Stripe's [example iOS apps](https://github.com/stripe/stripe-ios).
+
+It has a single endpoint, `/charge`, which takes 2 parameters (`stripeToken` and `amount`) to create a charge on your Stripe account.
+
+This is intended for example purposes only: you'll likely need something more serious for your production apps.
+
+To deploy this for free on Heroku, click this button:
+
+[![Deploy](https://www.herokucdn.com/deploy/button.png)](https://heroku.com/deploy)
+
+Then set the `backendChargeURLString` variable in our example apps to your Heroku URL (it'll be in the format https://my-example-app.herokuapp.com).
+
+Happy testing!
