 * Logging and debugging support
 
 ### Basic example
-    <?php
+```php
+<?php
 
-    require('smtp-validate-email.php');
+require('smtp-validate-email.php');
 
-    $from = 'a-happy-camper@campspot.net'; // for SMTP FROM:<> command
-    $email = 'someone@somewhere.net';
+$from = 'a-happy-camper@campspot.net'; // for SMTP FROM:<> command
+$email = 'someone@somewhere.net';
 
-    $validator = new SMTP_Validate_Email($email, $from);
-    $smtp_results = $validator->validate();
+$validator = new SMTP_Validate_Email($email, $from);
+$smtp_results = $validator->validate();
 
-    var_dump($smtp_results);
+var_dump($smtp_results);
+```
 
 ### Array usage
 The class supports passing an array of addresses in the constructor or to the
 `validate()` method. Checking multiple addresses on the same server uses
 a single connection.
+```php
+<?php
 
-    <?php
+require('smtp-validate-email.php');
 
-    require('smtp-validate-email.php');
+$from = 'a-happy-camper@campspot.net'; // for SMTP FROM:<> command
+$emails = array(
+    'someone@somewhere.net',
+    'some-other@somewhere-else.net',
+    'someone@example.com',
+    'someone-else@example.com'
+);
 
-    $from = 'a-happy-camper@campspot.net'; // for SMTP FROM:<> command
-    $emails = array(
-        'someone@somewhere.net',
-        'some-other@somewhere-else.net',
-        'someone@example.com',
-        'someone-else@example.com'
-    );
+$validator = new SMTP_Validate_Email($emails, $from);
+$smtp_results = $validator->validate();
 
-    $validator = new SMTP_Validate_Email($emails, $from);
-    $smtp_results = $validator->validate();
+// or passing to the validate() method
+// $validator = new SMTP_Validate_Email();
+// $smtp_results = $validator->validate($emails, $from);
 
-    // or passing to the validate() method
-    // $validator = new SMTP_Validate_Email();
-    // $smtp_results = $validator->validate($emails, $from);
-
-    var_dump($smtp_results);
+var_dump($smtp_results);
