+      <p>Below are some examples of files generated using glue-ar. Scan the QR codes to see the figures in AR on your phone! We provide three types of interactives for most of our examples:</p>
+      <ul>
+        <li><strong><em>model-viewer</em></strong>: These use Google's <a href="https://modelviewer.dev/">model-viewer</a> web component to allow you to view figures in tabletop AR directly from your phone. No app required!</li>
+        <li><strong><em>CoSpaces - tabletop</em></strong>: These allow viewing the model in AR using <a href="https://www.cospaces.io/">CoSpaces</a> in a tabletop format. This method requires installing the CoSpaces app.</li>
+        <li><strong><em>CoSpaces - MERGE</em></strong>: These also use CoSpaces, but allow holding the model in your hand via the <a href="https://mergeedu.com/cube">MERGE Cube</a>. To use these, you can either buy a MERGE Cube, or create your own <a href="https://support.mergeedu.com/hc/en-us/articles/360052933492-Making-a-Merge-Paper-Cube">paper MERGE Cube</a>. This method requires installing the CoSpaces app.</li>
