-## Omnipay for Laravel 5
+## Omnipay for Laravel
 
 This is a package to integrate [Omnipay](https://github.com/omnipay/omnipay) with Laravel.
 You can use it to easily manage your configuration, and use the Facade to provide shortcuts to your gateway.
 
 ## Installation
 
-Require this package in your composer.json and run composer update (or run `composer require barryvdh/laravel-omnipay:0.3.x` directly):
-
-    "barryvdh/laravel-omnipay": "0.3.*@dev"
+Require this package in your composer.json and run composer update (or run `composer require barryvdh/laravel-omnipay` directly):
 
+```php
+"barryvdh/laravel-omnipay": "0.3.*"
+```
+
 Pre Laravel 5.5: After updating composer, add the ServiceProvider to the providers array in config/app.php
 
-    'Barryvdh\Omnipay\ServiceProvider',
+```php
+'Barryvdh\Omnipay\ServiceProvider',
+```
 
 You need to publish the config for this package. A sample configuration is provided. The defaults will be merged with gateway specific configuration.
 
-    $ php artisan vendor:publish --provider='Barryvdh\Omnipay\ServiceProvider'
+```
+$ php artisan vendor:publish --provider='Barryvdh\Omnipay\ServiceProvider'
+```
 
 To use the Facade (`Omnipay::purchase()` instead of `App::make(`omnipay`)->purchase()`), add that to the facades array.
 
-     'Omnipay' => 'Barryvdh\Omnipay\Facade',
+```php
+'Omnipay' => 'Barryvdh\Omnipay\Facade',
+```
 
 When calling the Omnipay facade/instance, it will create the default gateway, based on the configuration.
 You can change the default gateway by calling `Omnipay::setDefaultGateway('My\Gateway')`.
 You can get a different gateway by calling `Omnipay::gateway('My\Cass')`
 
 ## Examples
 
-    $params = [
-        'amount' => $order->amount,
-        'issuer' => $issuerId,
-        'description' => $order->description,
-        'returnUrl' => URL::action('PurchaseController@return', [$order->id]),
-    ];
-    $response = Omnipay::purchase($params)->send();
-
-    if ($response->isSuccessful()) {
-        // payment was successful: update database
-        print_r($response);
-    } elseif ($response->isRedirect()) {
-        // redirect to offsite payment gateway
-        return $response->getRedirectResponse();
-    } else {
-        // payment failed: display message to customer
-        echo $response->getMessage();
-    }
+```php
+$params = [
+    'amount' => $order->amount,
+    'issuer' => $issuerId,
+    'description' => $order->description,
+    'returnUrl' => URL::action('PurchaseController@return', [$order->id]),
+];
+
+$response = Omnipay::purchase($params)->send();
+
+if ($response->isSuccessful()) {
+    // payment was successful: update database
+    print_r($response);
+} elseif ($response->isRedirect()) {
+    // redirect to offsite payment gateway
+    return $response->getRedirectResponse();
+} else {
+    // payment failed: display message to customer
+    echo $response->getMessage();
+}
+```
 
 Besides the gateway calls, there is also a shortcut for the creditcard:
 
-    $formInputData = array(
-        'firstName' => 'Bobby',
-        'lastName' => 'Tables',
-        'number' => '4111111111111111',
-    );
-    $card = Omnipay::CreditCard($formInputData);
+```php
+$formInputData = [
+    'firstName' => 'Bobby',
+    'lastName' => 'Tables',
+    'number' => '4111111111111111',
+];
+
+$card = Omnipay::CreditCard($formInputData);
+```
