 ## Usage
 
 To bootstrap the parser, you need to give it a `PhpParser` instance:
-
-    $parser = new PHPCfg\Parser(
-        new PhpParser\Parser(new PhpParser\Lexer)
-    ); 
-
+```php
+$parser = new PHPCfg\Parser(
+    new PhpParser\Parser(new PhpParser\Lexer)
+); 
+```
 Then, just call parse on a block of code, giving it a filename:
-
-    $block = $parser->parse(file_get_contents(__FILE__), __FILE__);
-
+```php
+$block = $parser->parse(file_get_contents(__FILE__), __FILE__);
+```
 To dump the graph, simply use the built-in dumper:
-
-    $dumper = new PHPCfg\Dumper;
-    echo $dumper->dump($block);
+```php
+$dumper = new PHPCfg\Dumper;
+echo $dumper->dump($block);
+```
