+    <h1>Triangles.fun</h1>
+    A game. Leave only a single dot to win. Eliminate other dots by jumping
+    them over!
+    <h2>Instructions</h2>
+    Click or touch the dot. If the dot can jump, it becomes lighter and the
+    spots where it can land become darker. Perform jump by touching or
+    clicking on the darker spot.
+    <h2>Installation</h2>
+    This game can be installed into your device. Look for "Add to Home
+    Screen" in the browser menu.
+    <h2>Support</h2>
+    You can send me your feedback or complains via
+    <a href="mailto:peter@triangles.fun">peter@triangles.fun</a>
+    and you can even
