+#### Overriding a Component’s Layout
+
+To override a component’s layout, follow these steps:
+
+1. Create a folder inside your theme's `partials` directory that matches the component's alias
+   (e.g., `/themes/custom/partials/mycomponent`) and add layout files such as `default.htm`, `special.htm`, etc.
+2. In your custom plugin's `Plugin.php` file, enable layout overrides in the `boot()` method by setting the
+   static property `$overrideLayout` to `true`. Example:
+
+   ```php
+   class Plugin extends PluginBase
+   {
+       public function boot()
+       {
+           \NumenCode\Widgets\Components\Promotions::$overrideLayout = true;
+       }
+   }
+   ```
