-        Sell stuff offline, accept Lightning payments. Powered by LNURL-pay.
+        The confirmation codes are words from a predefined sequential word list. Each new payment bumps the words sequence by 1. So you can check the confirmation codes manually by just looking at them.
+      </p>
+      <p>
+        For example, if your wordlist is <code>[apple, banana, coconut]</code> the first purchase will be <code>apple</code>, the second <code>banana</code> and so on. When it gets to the end it starts from the beginning again.
