 ### Step 3: Use it
 ```php
 $users = new Models\User();
-$dataTable = new \LiveControl\EloquentDataTable\DataTable($users, ['email', 'firstname', 'lastname']);
+$dataTable = new LiveControl\EloquentDataTable\DataTable($users, ['email', 'firstname', 'lastname']);
 echo json_encode($dataTable->make());
 ```
 
+### Optional step 4: Set versions of DataTables plugin.
+Just initialize the DataTable object as you would normally and call the setVersionTransformer function as in the following example (for version 1.09 of DataTables):
+```php
+$dataTable->setVersionTransformer(new LiveControl\EloquentDataTable\VersionTransformers\Version109Transformer());
+```
+By default the plugin will be loading the transformer which is compatible with DataTables version 1.10.
