+### Live dashboard
+
+#### Usage
+
+The realtime compiler comes with a live dashboard that you can access at `http://localhost:8080/dashboard`.
+
+From here, you can visually interact with your site content, including creating new pages and posts.
+
+The live dashboard is not saved to your static site, and is only available through the development server.
+
+#### Configuration
+
+The dashboard can be customized, and disabled, in the `config/hyde.php` file.
+
+```php
+// filepath config/hyde.php
+
+'server' => [
+    'dashboard' => [
+        'enabled' => env('SERVER_DASHBOARD', true),
+        'interactive' => true,
+        'tips' => true,
+    ],
+],
+```
+
+_The dashboard was added in Realtime Compiler v3.0.0 (March 2023), with interactive features added in v3.1.0 (October 2023)_
+
+### Live edit
+
+#### Usage
+
+The live edit feature allows you to quickly edit Markdown-based pages (posts, docs, and pages) directly in the browser.
+
+To enter the live editor, simply double-click on the article you want to edit, and it will be replaced with a text editor.
+When you're done, click the save button to save the changes to the page's source file.
+
+#### Shortcuts
+
+The live editor supports the following keyboard shortcuts:
+- `Ctrl + E` - Enter/Exit editor
+- `Ctrl + S` - Save changes
+- `esc` - Exit editor if active
+
+#### Configuration
+
+The live editor can be disabled in the `config/hyde.php` file.
+The live editor plugin code will not be saved to your static site.
+
+```php
+// filepath config/hyde.php
+
+'server' => [
+    'live_edit' => env('SERVER_LIVE_EDIT', true),
+],
+```
+
+_The live editor was added in Hyde Realtime Compiler Server v3.2.0 (November 2023)_
