 For example, to publish message to RabbitMQ is as simple as this:
 
-		$producer = new Thumper\Producer($connection);
-		$producer->setExchangeOptions(array('name' => 'hello-exchange', 'type' => 'direct'));
-		$producer->publish($argv[1]);
+```php
+$producer = new Thumper\Producer($connection);
+$producer->setExchangeOptions(array('name' => 'hello-exchange', 'type' => 'direct'));
+$producer->publish($argv[1]);
+```
 
 And then to consume them on the other side of the wire:
 
-		$myConsumer = function($msg)
-		{
-		  echo $msg, "\n";
-		};
-
-		$consumer = new Thumper\Consumer($connection);
-		$consumer->setExchangeOptions(array('name' => 'hello-exchange', 'type' => 'direct'));
-		$consumer->setQueueOptions(array('name' => 'hello-queue'));
-		$consumer->setCallback($myConsumer); //myConsumer could be any valid PHP callback
-		$consumer->consume(5); //5 is the number of messages to consume.
+```php
+$myConsumer = function($msg)
+{
+  echo $msg, "\n";
+};
+
+$consumer = new Thumper\Consumer($connection);
+$consumer->setExchangeOptions(array('name' => 'hello-exchange', 'type' => 'direct'));
+$consumer->setQueueOptions(array('name' => 'hello-queue'));
+$consumer->setCallback($myConsumer); //myConsumer could be any valid PHP callback
+$consumer->consume(5); //5 is the number of messages to consume.
