+        For each category of images, you will be presented with the 15 possible
+        choices. The categories are shuffled at every login. They will not
+        always appear in the same order.
+      </li>
+      <li>
+        At each category, only one of the 15 displayed choices is the correct
+        image that belongs to your pazzle. Find it and tap or click on that one.
+        The 15 images are shuffled too, they will not appear at the same
+        position at each login. On a computer, you can also use the tab key on
+        your keyboard to move to the desired item on the screen.
+      </li>
+      <li>
+        Once you completed the last category, you will be presented with all the
+        images you have previously selected. Their order is displayed as it was
+        when you picked them. But this is not the correct order of the images in
+        your pazzle. You now have to order them correctly.
+      </li>
+      <li>
+        You must remember which image should be the first one in your pazzle.
+        Find it on the screen and click or tap on it. It will be greyed out and
+        the number 1 will appear on top of it.
+      </li>
+      <li>
+        Move on to the second image of your pazzle (that you memorized). Find it
+        on the screen and tap on it. Repeat this step until you reached the last
+        image.
+      </li>
+      <li>
+        Finally, your PIN code will be asked. enter it by clicking or tapping on
+        the digits.
