+<h2><strong>Versioning Policy</strong></h2>
+
+<p>
+  Managed Valheim uses a structured versioning format:
+</p>
+
+<pre><code>MAJOR.MINOR.PATCH.BUILD</code></pre>
+
+<ul>
+  <li><strong>MAJOR</strong> — Breaking changes or architectural shifts</li>
+  <li><strong>MINOR</strong> — New features or enhancements</li>
+  <li><strong>PATCH</strong> — Bug fixes or stability improvements</li>
+  <li><strong>BUILD</strong> — Internal build increments or deployment tags</li>
+</ul>
+
+<p>
