+Billing Engine
+====================
+
+Currently, this engine support billing via Braintree. More backends to come later.
+
+Configuration
+----------------------------------
+
+Start with a sandbox account, which you can get here: https://www.braintreepayments.com/get-started
+
+Once you have registered for the sandbox, logging in will show you three important variables you will need to configure:
+
+* merchantId
+* publicKey
+* privatekey
+
+To configure the billing engine, edit `config/config.yaml` like so:
+
+    production: (or "development", as you prefer)
+      billing:
+        braintree:
+          environment: sandbox
+          merchant_id: Ohp2aijaaqu6oJ4w
+          public_key: ahnar0UwLahwe6Ce
+          private_key: aemie2Geohgah2EaOad9DeeruW4Iegh4
+
+If deploying via puppet, the same data in webapp.json would like this:
+
+    "billing": {
+      "braintree": {
+        "environment": "sandbox",
+        "merchant_id": "Ohp2aijaaqu6oJ4w",
+        "public_key": "ahnar0UwLahwe6Ce",
+        "private_key": "aemie2Geohgah2EaOad9DeeruW4Iegh4"
+      }
+    }
+
+Now, you should be able to add charges to your own sandbox when you run the webapp.
+
+The acceptable values for `billing.braintree.environment` are: `development`, `qa`, `sandbox`, or `production`.
+
+Plans
+--------------------------------
+
+You also will want to add a Plan to your Sandbox. Within the Braintree Sandbox, navigate to 'Recurring Billing' -> 'Plans'. From here, you can add a new Plan. The values of the test plan are not important, but the ID will be displayed, so should pick something descriptive.
+
+Here are credit cared numbers to try in the Sandbox:
