+## Installation
 
 The recommended way to install EmailReplyParser is through
 [Composer](http://getcomposer.org/):

 You get an `Email` object that contains a set of `Fragment` objects. The `Email`

-* `getFragments()`: returns all fragments;
-* `getVisibleText()`: returns a string which represents the content considered
+- `getFragments()`: returns all fragments;
+- `getVisibleText()`: returns a string which represents the content considered
   as "visible".
 
 The `Fragment` represents a part of the full email content, and has the
 following API:
 
-``` php
+```php
 <?php
 
 $fragment = current($email->getFragments());

 Alternatively, you can rely on the `EmailReplyParser` to either parse an email
 or get its visible content in a single line of code:
 
-``` php
+```php
 $email = \EmailReplyParser\EmailReplyParser::read($emailContent);
 
 $visibleText = \EmailReplyParser\EmailReplyParser::parseReply($emailContent);
