+Finder Component
+================
+
+Finder finds files and directories via an intuitive fluent interface.
+
+```php
+use Symfony\Component\Finder\Finder;
+
+$finder = new Finder();
+
+$iterator = $finder
+  ->files()
+  ->name('*.php')
+  ->depth(0)
+  ->size('>= 1K')
+  ->in(__DIR__);
+
+foreach ($iterator as $file) {
+    print $file->getRealpath()."\n";
+}
+```
+
+The iterator returns instances of [Symfony\Component\Finder\SplFileInfo\SplFileInfo][1].
+Besides the build-in methods inherited from [\SplFileInfo][2] (`getPerms()`, `getSize()`, ...),
+you can also use `getRelativePath()` and `getRelativePathname()`. Read the
+[official documentation][3] for more information.
+
+But you can also use it to find files stored remotely like in this example where
+we are looking for files on Amazon S3:
+
+```php
+$s3 = new \Zend_Service_Amazon_S3($key, $secret);
+$s3->registerStreamWrapper("s3");
+
+$finder = new Finder();
+$finder->name('photos*')->size('< 100K')->date('since 1 hour ago');
+foreach ($finder->in('s3://bucket-name') as $file) {
+    print $file->getFilename()."\n";
+}
+```
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Finder/
+    $ composer install
+    $ phpunit
+
+[1]: http://api.symfony.com/2.5/Symfony/Component/Finder/SplFileInfo.html
