 ## PDFLayer API bridge for Laravel 5
 
 Require this package in your composer.json and update composer. This will download the package and the dompdf + fontlib libraries also.
-
-    composer require mathieutu/laravel-pdflayer
+```bash
+composer require mathieutu/laravel-pdflayer
+```
 
 ## Installation
-
 ### Laravel 5.x:
 
 After updating composer, add the ServiceProvider to the providers array in config/app.php
-
-    MathieuTu\PDFLayer\PDFLayerServiceProvider::class,
+```php
+MathieuTu\PDFLayer\PDFLayerServiceProvider::class,
+```
 
 You can optionally use the facade for shorter code. Add this to your facades:
-
-        'PDF' => MathieuTu\PDFLayer\Facades\PDF::class,
+```php
+'PDF' => MathieuTu\PDFLayer\Facades\PDF::class,
+```
 
 ## Using
 
 You can create a new PDFLayer instance and load a HTML string, file, view name or even an url. 
 You can save it to a file, stream (show in browser) or download.
 
 To create an new instance, you can use the `App` class, the `app()` helper, use the [facade](https://laravel.com/docs/5.3/facades), or (better) use [automatic dependency injection](https://laravel.com/docs/5.3/controllers#dependency-injection-and-controllers) :
-
-    $pdf = App::make('pdflayer');
-    $pdf = app('pdflayer');
-    $pdf = PDF::anyMethod();
-    function (MathieuTu\PDFLayer\PDF $pdf) {}
-
+```php
+$pdf = App::make('pdflayer');
+$pdf = app('pdflayer');
+$pdf = PDF::anyMethod();
+function (MathieuTu\PDFLayer\PDF $pdf) {}
+```
 You can chain the methods:
-
-    return $pdf->loadView('pdf.invoice', $data)->setPaper('a4', 'landscape')->save('/path-to/my_stored_file.pdf')->stream('download.pdf');
-
+```php
+return $pdf->loadView('pdf.invoice', $data)->setPaper('a4', 'landscape')->save('/path-to/my_stored_file.pdf')->stream('download.pdf');
+```
 You can set all the parameters given by the [pdflayer documentation](https://pdflayer.com/documentation) by using the `setXXX` method where XXX is the parameter in StudlyCase, or just set the parameter (in original snake_case) as attribute of the object.
-
-    $pdf->loadHTML(<h1>Hello!</h1>)->setWatermarkInBackground(true);
-    $pdf->margin_top = 134;
-    $pdf->save('myfile.pdf');
-
+```php
+$pdf->loadHTML('<h1>Hello!</h1>')->setWatermarkInBackground(true);
+$pdf->margin_top = 134;
+$pdf->save('myfile.pdf');
+```
 If you need the output as a string, you can get the rendered PDF with the output() function, so you can directly send it by email, for example.
