+## PDF Wrapper extension
+
+This package has own wrapper for the Mpdf\Mpdf class. But it can be also overrided or extended on the project level.

+There is a setting in the config file to use a custom PdfWrapper.

+```php
+return [
+    // ...
+    'pdfWrapper' => 'misterspelik\LaravelPdf\Wrapper\PdfWrapper',

+The only requirement that the wrapper must implement the interface
+`misterspelik\LaravelPdf\PdfInterface\PdfWrapperInterface`
