+```php
+return [
+    //....
+    'components' => [
+        'dotenv' => [
+            'class' => 'cyberinferno\yii\phpdotenv\Loader',
+            'file' => '.env', // Optional parameter if custom environment variable directory
+            'overload' => false, // Optional parameter whether to overload already existing environment variables. Defaults to false
+        ],
+    ]
+];
