+DomCrawler Component
+====================
+
+DomCrawler eases DOM navigation for HTML and XML documents.
+
+If you are familiar with jQuery, DomCrawler is a PHP equivalent:
+
+```php
+use Symfony\Component\DomCrawler\Crawler;
+
+$crawler = new Crawler();
+$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
+
+print $crawler->filterXPath('descendant-or-self::body/p')->text();
+```
+
+If you are also using the CssSelector component, you can use CSS Selectors
+instead of XPath expressions:
+
+```php
+use Symfony\Component\DomCrawler\Crawler;
+
+$crawler = new Crawler();
+$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
+
+print $crawler->filter('body > p')->text();
+```
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/DomCrawler/
+    $ composer install
+    $ phpunit
