 A useful usage would be for configuring the ``eslint-loader`` to lint Vue files too.
 The following code is equivalent:
 
 .. code-block:: javascript
 
-    // Before
+    // Manually
     const webpackConfig = Encore.getWebpackConfig();
 
     const eslintLoader = webpackConfig.module.rules.find(rule => rule.loader === 'eslint-loader');
     eslintLoader.test = /\.(jsx?|vue)$/;
 
     return webpackConfig;
 
-    // After
+    // Using Encore.configureLoaderRule()
     Encore.configureLoaderRule('eslint', loaderRule => {
         loaderRule.test = /\.(jsx?|vue)$/
     });
