+  <h1>The <u>T</u>erse <u>P</u>ublic <u>L</u>icense Family</h1>
+  <p>A family of minimal licenses for artists and developers, without
+     the sheer size of the more thorough licenses. If you forsee
+     yourself going to court, maybe pick something more robust. If you
+     just want something simple for a small project, this may well be
+     for you.</p>
+  <p>Feel free to <a href="https://amehut.dev/~aleteoryx/tpl">suggest
+     improvements</a>.</p>
