 ## Remove a component {#remove}
 
-To remove a component from layout rendering, you need to create a [plugin]({{ page.baseurl }}/extension-dev-guide/plugins.html) for the `\Magento\Checkout\Block\Checkout\LayoutProcessor::process` method. In your plugin, implement the around method removing the corresponding layout nodes at run-time.
+If you want to keep a component from being rendered, you need to create a layout processor. A layout processor consists of a class, implementing
+the `\Magento\Checkout\Block\Checkout\LayoutProcessorInterface` interface, and thus a `LayoutProcessorInterface::process($jsLayout)` method.
+
+```php
+<?php
+
+namespace <Vendor>\<Module>\Block\Checkout;
+
+use Magento\Checkout\Block\Checkout\LayoutProcessorInterface;
+
+class OurLayoutProcessor implements LayoutProcessorInterface
+{
+    /**
+     * @param array $jsLayout
+     * @return array
+     */
+    public function process($jsLayout)
+    {
+        //%path_to_target_node% is the path to the component's node in checkout_index_index.
+        unset($jsLayout['components']['checkout']['children']['steps'][%path_to_target_node%]);
+        return $jsLayout;
+    }
+}
+```
 
-The following sample is an example of the around method removing a component:
+Once created you can add the layout processor through Dependency Injection (DI).
 
-```php?start_inline=1
-unset($jsLayout['components']['checkout']['children']['steps'][%path_to_target_node%]); //%path_to_target_node% is the path to the component's node in checkout_index_index.xml
-return $jsLayout;
+```xml
+<?xml version="1.0"?>
+<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

 If you want to use this sample in your code, replace the `%path_to_target_node%` placeholder with real value.
