+<h1>Fonts for BQN</h1>
+
+<p>This page displays samples of all four free fonts I know of that fully support BQN's character set:</p>
+<ul>
+  <li><a href="https://github.com/mlochbaum/BQN/blob/master/docs/DejaVuBQNSansMono.ttf">DejaVu Sans Mono BQN</a>, which I adapted from DejaVu Sans Mono</li>
+  <li><a href="https://github.com/dzaima/BQN386">BQN386</a>, derived from APL385 by way of APL386</li>
+  <li><a href="http://www.kreativekorp.com/software/fonts/fairfaxhd.shtml">Fairfax HD</a></li>
+  <li><a href="https://github.com/cormullion/juliamono">Julia Mono</a></li>
+</ul>
+<p>Other than DejaVu, the versions embedded on this page are small subsets, and you should get your copy from the links above (unless perhaps you want to use them for embedding as well). In addition to these, <a href="https://www.fsd.it/shop/fonts/pragmatapro/">Pragmata Pro</a> and <a href="https://www.evertype.com/emono/">Everson Mono</a> have full support, but each charges a significant fee for usage and I can't freely embed them here.</p>
+
+<p style="margin-top:3em">The table below shows samples of the whole BQN keyboard (which includes the entire BQN character set plus a few unused characters) and APL characters that don't feature in BQN.</p>
