+<h1>Configuring the server</h1>
+
+<p>The server's config file is JSON. It can either be in simple mode (for basic configurations), or in low-level mode (for any sort of crazy configuration).</p>
+
+<p>This page documents the simple configuration mode.</p>
+
+<p>If you visit your Camlistore server's /setup page (by default, at
+http://localhost:3179/setup) you can modify the config file from your
+web browser and restart the server.</p>
