 ### Client side
 
-Include the following codeblock into your presentation's configuration:
+First, include the dependencies. On Reveal.js 4x. use the following code:
 
-```javascript
-    Reveal.initialize({
-    // ...
-    /*
+```html
+    <!--
         reveal.js-remote:
-        optional configuration (with default values)
-    */
-    remote: {
-        // enable remote control
-        //remote: true,
+        The next two dependencies are required!
+        If you do not serve the presentations from the presentations/-folder
+        give the full servername here, e.g.
+
+        https://presentations.jowisoftware.de/soket.io/socket.io.js and
+        https://presentations.jowisoftware.de/_remote/plugin.js_
+    -->
+    <script src="../socket.io/socket.io.js"></script>
+    <script src="../_remote/plugin.js"></script>
+```
 
-        // enable multiplexing
-        //multiplex: true,
+Next, load the plugin as usual:
 
-        // server address
-        // change this if you do not serve the presentation from the same domain
-        // example: https://presentations.jowisoftware.de
-        //server: window.location.protocol + "//" + window.location.host + "/",
+```javascript
+    Reveal.initialize({
+        // …
+        plugins: [ /* other, plugins, e.g. RevealMarkdown */, RevealRemote ]
+        // –
+    });
+```
 
-        // path to socket.io
-        // change this if the basepath of the server is not "/"
-        //path: "/socket.io",
+On Reveal.js v 3.x, include the scripts as dependencies instead:
 
-        // url of the presentation to share
-        //shareUrl: window.location.href
-    },
+```javascript
+    Reveal.initialize({
