+💡 <strong>Tip — Migrating from Gemini CLI?</strong><br>
+If you previously installed this extension with <code>gemini extensions install</code>, you can convert it to an Antigravity plugin instead of reinstalling from scratch:
+<ul>
+  <li><strong>On first launch of Antigravity CLI</strong>, accept the Migration Options prompt to automatically convert your installed Gemini CLI extensions to Antigravity plugins.</li>
+  <li><strong>Or, from your terminal</strong>, run:
+    <pre><code class="language-bash">agy plugin import gemini</code></pre>
+  </li>
+</ul>
+See <a href="https://antigravity.google/docs/gcli-migration">Migrating from Gemini CLI</a> for details on plugins, context files (<code>GEMINI.md</code> / <code>AGENTS.md</code>), and MCP server config differences.
