 ## Usage
 
 Now you can use the channel in your `via()` method inside the notification:
 
 ``` php
-use NotificationChannels\TwilioNotifications\Channel;
-use NotificationChannels\TwilioNotifications\SmsMessage;
+use NotificationChannels\Twilio\TwilioChannel;
+use NotificationChannels\Twilio\TwilioSmsMessage;
 use Illuminate\Notifications\Notification;
 
 class AccountApproved extends Notification
 {
     public function via($notifiable)
     {
-        return [Channel::class];
+        return [TwilioChannel::class];
     }
 
     public function toTwilio($notifiable)
     {
-        return (new SmsMessage())
+        return (new TwilioSmsMessage())
             ->content("Your {$notifiable->service} account was approved!");
     }
 }
 ```
 
-### Setting up your Twilio account
+You can also create a Twilio call:
 
-TODO
+``` php
+use NotificationChannels\Twilio\TwilioChannel;
+use NotificationChannels\Twilio\TwilioCallMessage;
+use Illuminate\Notifications\Notification;
 
-## Usage
+class AccountApproved extends Notification
+{
+    public function via($notifiable)
+    {
+        return [TwilioChannel::class];
+    }
 
-TODO
+    public function toTwilio($notifiable)
+    {
+        return (new TwilioCallMessage())
+            ->url("http://example.com/your-twiml-url");
+    }
+}
+```
+
+In order to let your Notification know which phone are you sending/calling to, add the `routeNotificationForTwilio` method to your Notifiable model.
+
+```php
+public function routeNotificationForTwitter()
+{
+    return '+1234567890';
+}
+```
