+## Introduction
+
 This is a simple Laravel Service Provider providing access to the  [Nexmo PHP Client Library][client-library].
 
 Installation
 ------------
 
 To install the PHP client library using Composer:
 
-    composer require nexmo/laravel
+```bash
+composer require nexmo/laravel
+```
 
 Alternatively, add these two lines to your composer require section:
 
-    "nexmo/laravel": "^1.0"
+```json
+{
+    "require": {
+        "nexmo/laravel": "^1.0"
+    }
+}
+```
 
 ### Laravel 5.5+
 
@@ -21,49 +40,69 @@ If you're using Laravel 5.5 or above, the package will automatically register th
 
 Add `Nexmo\Laravel\NexmoServiceProvider` to the `providers` array in your `config/app.php`:
 
-    Nexmo\Laravel\NexmoServiceProvider::class
+```php
+'providers' => [
+    // Other service providers...
+
+    Nexmo\Laravel\NexmoServiceProvider::class,
+],
+```
 
 If you want to use the facade interface, you can `use` the facade class when needed:
 
-    use Nexmo\Laravel\Facade\Nexmo;
+```php
+use Nexmo\Laravel\Facade\Nexmo;
+```
 
 Or add an alias in your `config/app.php`:
 
-    'Nexmo' => \Nexmo\Laravel\Facade\Nexmo::class
+```php
+'aliases' => [
+    ...
+    'Nexmo' => Nexmo\Laravel\Facade\Nexmo::class,
+],
+```
 
 Configuration
 -------------
 
 You can use `artisan vendor:publish` to copy the distribution configuration file to your app's config directory:
 
-    php artisan vendor:publish
+```bash
+php artisan vendor:publish
+```
 
 Then update `config/nexmo.php` with your credentials. Alternatively, you can update your `.env` file with the following:
 
-```
-NEXMO_KEY = my_api_key
-NEXMO_SECRET = my_secret
+```dotenv
+NEXMO_KEY=my_api_key
+NEXMO_SECRET=my_secret
 ```
 
 Usage
 -----
 
 To use the Nexmo Client Library you can use the facade, or request the instance from the service container:
 
-    Nexmo::message()->send([
-        'to' => '14845551244',
-        'from' => '16105552344',
-        'text' => 'Using the facade to send a message.'
-    ]);
+```php
+Nexmo::message()->send([
+    'to'   => '14845551244',
+    'from' => '16105552344',
+    'text' => 'Using the facade to send a message.'
+]);
+```
+
+Or
 
-    //or
+```php
+$nexmo = app('Nexmo\Client');
 
-    $nexmo = app('Nexmo\Client');
-    $nexmo->message()->send([
-        'to' => '14845551244',
-        'from' => '16105552344',
-        'text' => 'Using the instance to send a message.'
-    ]);
+$nexmo->message()->send([
+    'to'   => '14845551244',
+    'from' => '16105552344',
+    'text' => 'Using the instance to send a message.'
+]);
+```
