+  <h1>Select your payment method</h1>
+
+  <p>
+    This is an example for a "checkout" page of a Web shop.
+    On the previous page, you have created the shopping cart
+    and decided which product to buy (i.e. which project to
+    donate KUDOS to).  Now in this page, you are asked to
+    select a payment option.  As Taler is not yet universally
+    used, we expect merchants will offer various payment options.
+  </p>
+  <p>
+    The page also demonstrates how to only enable (or show) the Taler
+    option if Taler is actually supported by the browser.  For example,
+    if you disable the Taler extension now, the Taler payment option
+    will be disabled in the page.  Naturally, you could also trivially
+    hide the Taler option entirely by changing the visibility instead.
+  </p>
+  <p>
+    Note that you MUST select Taler here for the demo to continue,
+    as the other payment options are just placeholders and not
+    really working in the demonstration.  Also, it is of course
+    possible to ask the user to make this choice already on the
+    previous page (with the shopping cart), we just separated the
+    two steps to keep each step as simple as possible.

you
+    got to see.  But do not worry, you will be given the opportunity to review
+    the final offer from the merchant in a window secured by the Taler
+    extension.  That way, you can spot the error before committing to an
+    incorrect contract.
