      <p>
        Before you start, you need to:
        <ul>
          <li><a href="https://stripe.com/docs/stripe-js/elements/payment-request-button#html-js-testing" target="_blank">Add a payment method to your browser.</a> For example, you can <a href="chrome://settings/payments" target="_blank">save a card</a> in Chrome.</li>
          <li>Serve your application over HTTPS. This is a requirement both in development and in production. One way to get up and running is to use a service like <a href="https://ngrok.com/" target="_blank">ngrok</a>.</li>
        </ul>
      </p>
