-To use this extension, you can use it in to ways, whether you configure it on your application file or you use it
+The following example shows how to use this extension:
-directly.
 
-The following shows how to use it via application configuration file:  
+```php
-
-```
-// configuring on your application configuration file
-'components' => [
-    'image' => [
-        'class' => 'yii\imagine\Image',
-        'driver' => \yii\imagine\Image::DRIVER_GD2,

-
-// Once configured you can access to the extension like this:
-$img = Yii::$app->image->thumb('path/to/image.jpg', 120, 120);
-
-```
-
-This is how to use it directly:
-
-```
 use yii\imagine\Image;
 
-$image = new Image();
-$img = $image->thumb('path/to/image.jpg', 120, 120);
-```
-**About the methods**  
-Each method returns an instance to `\Imagine\Image\ManipulatorInterface`, that means that you can easily make use of the methods included in the `Imagine` library: 
-
-```
 // frame, rotate and save an image
-
+Image::frame('path/to/image.jpg', 5, '666', 0)

     ->save('path/to/destination/image.jpg', ['quality' => 50]);
 ```
+
+Note that each `Image` method returns an instance of `\Imagine\Image\ImageInterface`.
+This means you can make use of the methods included in the `Imagine` library:
