+### Braintree
+#### Creating an Apple Pay certificate
+Follow Braintree's [documentation](https://developers.braintreepayments.com/guides/apple-pay/configuration/ios/v4#apple-pay-certificate-request-and-provisioning) on how to create and upload the Apple Pay certificate back to Braintree.
+
+#### Adding and Linking the Braintree SDK
+Next, you'll need to add Braintree's SDK to your project.  You can install it by following one of the methods [listed in Braintree's documentation](https://github.com/braintree/braintree_ios#installation).
+
+Finally, in Xcode:
+1. Select the `ReactNativePayments` project from the left sidebar (under Libraries)
+2. Select `Build Settings` and search for `Header Search Paths`
+3. Then add the path to where you added the Library (remember, it's relative to `/node_modules/react-native-payments/lib/ios`)
+

+    {

+        merchantIdentifier: 'merchant.com.your-app.namespace',
+        supportedNetworks: ['visa', 'mastercard'],
+        countryCode: 'US',
+        currencyCode: 'USD',
++       paymentMethodTokenizationParameters: {
++         parameters: {
++           'gateway': 'braintree',
++           'braintree:tokenizationKey': 'your-tokenization-key'
++         }
++       }
+      }
