+# Configuring a DocuSign payments gateway
+
+DocuSign offers built-in connections to multiple payment
+gateways. The payments example uses a demo account via the Stripe
+gateway service.
+
+## Creating the payments gateway account
+
+1. Login to demo.docusign.net and go to the Admin Tool.
+1. On the Integrations / Payments screen, click Stripe.
+1. For development, you can skip the Stripe account application
+   by using the `Skip this account form` link:
+
+   ![Skipping the Stripe account form](docs/stripe_skip_account_form_link.png)
+1. Next, your browser will show that an enabled Stripe
+   payment gateway account has been associated with your
+   DocuSign demo sandbox account.
+1. Configure the example launcher with the gateway account id shown in the Admin tool.
