+Using Gii generator
+-------------------
+
+This extension provides a code generator, which can be integrated with yii 'gii' module. It allows generation of the
+Active Record code. In order to enable it, you should adjust your application configuration in following way:
+
+```php
+return [
+    //....
+    'modules' => [
+        // ...
+        'gii' => [
+            'class' => 'yii\gii\Module',
+            'generators' => [
+                'mongoDbModel' => [
+                    'class' => 'yii\mongodb\gii\model\Generator'
+                ]
+            ],
+        ],
+    ]
+];
+```
+
+> Note: since MongoDB is schemaless, there is not much information, which generated code may base on. So generated code
+  is very basic and definitely requires adjustments.
