+An extension of the [Codebird](https://github.com/mynetx/codebird-php) class to use WordPress' HTTP API instead of cURL.

 Usage
 --------------------
 
 Include both the Codebird library and `class-wp-codebird.php`, then get a new instance of `WP_Codebird`:
 
-    $wp_codebird = WP_Codebird::getInstance();
+```php
+$wp_codebird = WP_Codebird::getInstance();
+```
 
 The rest of the api is identical to Codebird - it is a drop in replacement that does not require any modification to existing code.
