+<h1><strong>Installation</strong></h1>
+
+<p>
+  This page explains how to install and deploy the 
+  <strong>Managed Valheim</strong> server container on TrueNAS SCALE or any 
+  OCI-compatible environment. It covers image selection, environment variables, 
+  volume setup, and initial startup.
+</p>
+
+<hr>
+
+<h2><strong>1. Choose an Image Version</strong></h2>
+
+<p>
+  The container is published to your private registry. Select a versioned tag 
+  for stable deployments:
+</p>
+
+<pre><code>gitea.theminisip.ca/mini-server-manager/managed-valheim:1.0.1.1</code></pre>
+
+<p>
+  You may also use <code>latest</code>, but pinned versions are recommended for 
+  production servers to ensure predictable behavior.
+</p>
+
+<hr>
+
+<h2><strong>2. Create Required Volumes</strong></h2>
+
+<p>
+  The server requires two persistent volumes:
+</p>
+
+<ul>
+  <li><code>/config</code> — runtime configuration and metadata</li>
+  <li><code>/backups</code> — world backup storage</li>
+</ul>
+
+<p>
+  On TrueNAS SCALE, these map to datasets you select during app installation.
+</p>
+
+<hr>
+
+<h2><strong>3. Configure Environment Variables</strong></h2>
+
+<p>
+  The container is fully configurable through environment variables. At minimum, 
+  set the following:
+</p>
+
+<table>
+  <thead>
+    <tr>
+      <th>Variable</th>
+      <th>Default</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td><code>SERVER_NAME</code></td>
+      <td>Valheim Server</td>
+      <td>Name shown in the server browser</td>
+    </tr>
+    <tr>
+      <td><code>WORLD_NAME</code></td>
+      <td>Dedicated</td>
+      <td>World save name</td>
+    </tr>
+    <tr>
+      <td><code>SERVER_PASSWORD</code></td>
+      <td>changeme</td>
+      <td>Password required to join</td>
+    </tr>
+    <tr>
+      <td><code>PUBLIC</code></td>
+      <td>1</td>
+      <td>Public listing toggle</td>
+    </tr>
+  </tbody>
+</table>
+
+<p>
+  Backup automation is also configurable:
+</p>
+
+<table>
+  <thead>
+    <tr>
+      <th>Variable</th>
+      <th>Default</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td><code>BACKUP_INTERVAL</code></td>
+      <td>21600</td>
+      <td>Backup interval (seconds). Default is 6 hours.</td>
+    </tr>
+    <tr>
+      <td><code>BACKUP_RETENTION_DAYS</code></td>
+      <td>7</td>
+      <td>Days to retain backups before pruning.</td>
+    </tr>
+  </tbody>
+</table>
+
+<p>
+  Internal directories used by the container:
+</p>
+
+<ul>
+  <li><code>/opt/valheim_base</code> — clean SteamCMD install</li>
+  <li><code>/opt/valheim</code> — modded runtime directory</li>
+  <li><code>/opt/steamcmd</code> — SteamCMD installation</li>
+</ul>
+
+<hr>
+
+<h2><strong>4. Expose Required Ports</strong></h2>
+
+<p>
+  Valheim requires three UDP ports:
+</p>
+
+<pre><code>2456/udp
+2457/udp
+2458/udp
+</code></pre>
+
+<p>
+  TrueNAS SCALE will automatically expose these based on your app configuration.
+</p>
+
+<hr>
+
+<h2><strong>5. Deploy the App on TrueNAS SCALE</strong></h2>
+
+<p>
+  To install the server on TrueNAS SCALE:
+</p>
+
+<ol>
+  <li>Open <strong>Apps → Installed → Add</strong>.</li>
+  <li>Select your custom catalog entry for Managed Valheim.</li>
+  <li>Choose the desired image tag (e.g., <code>1.0.1.1</code>).</li>
+  <li>Configure environment variables.</li>
+  <li>Assign volumes for <code>/config</code> and <code>/backups</code>.</li>
+  <li>Save and deploy.</li>
+</ol>
+
+<p>
+  On first startup, the container will:
+</p>
+
+<ul>
+  <li>Install or update Valheim via SteamCMD</li>
+  <li>Copy updated binaries into the modded directory</li>
+  <li>Download and install BepInEx</li>
+  <li>Generate the managed wrapper script</li>
+  <li>Start the Valheim server</li>
+  <li>Begin automated backups</li>
+</ul>
+
+<hr>
+
+<h2><strong>6. Verify Installation</strong></h2>
+
+<p>
+  You can verify the server is running by checking:
+</p>
+
+<ul>
+  <li>TrueNAS SCALE app logs</li>
+  <li>Container logs (stdout)</li>
+  <li>BepInEx logs under <code>/opt/valheim/BepInEx/</code></li>
+</ul>
+
+<p>
+  The server will appear in the Valheim server browser if 
+  <code>PUBLIC=1</code> is set.
+</p>
+
+<hr>
+
+<h2><strong>7. Optional: Mod Installation</strong></h2>
+
+<p>
+  Mods can be added by placing files into:
+</p>
+
+<pre><code>/opt/valheim/BepInEx/plugins</code></pre>
+
+<p>
+  These files persist across updates because the modded directory is preserved 
+  during the SteamCMD update cycle.
+</p>
