+
+If you are looking for a production-ready PHP framework, please use
+[Yii v1.1](https://github.com/yiisoft/yii).
+
+Yii 2.0 is still under heavy development. We may make significant changes
+without prior notices. **Yii 2.0 is not ready for production use yet.**
+
+[![Build Status](https://secure.travis-ci.org/yiisoft/yii2.png)](http://travis-ci.org/yiisoft/yii2)
+
+This is the yii2 composer installer.
+
+Installation
+----------------
+

+
+*Note: You might have to run `php composer.phar selfupdate` before using this extension.*
+
+
+Usage & Documentation
+-----------
+This extensions allows you to hook to certain composer events and prepare your yii2-app for usage.
+
+After the package is installed, the composer.json file has to be modified to enable this extension.
+
+To see it in action take a look at the example apps in the repository:
+
+[Basic](https://github.com/suralc/yii2/blob/master/apps/basic/composer.json#L27)
+[Advanced](https://github.com/suralc/yii2/blob/extensions-readme/apps/advanced/composer.json)
+
+However it might be useful to read through the official composer [documentation](http://getcomposer.org/doc/articles/scripts.md) to understand what this extension can to for you and what it can't. 
+
+You can also use this as an template to create your own composer additions to ease development and deployment of your app.

+Yii 2.0 Public Preview - Smarty View Renderer
+======================
+
+Thank you for choosing Yii - a high-performance component-based PHP framework.
+
+If you are looking for a production-ready PHP framework, please use
+[Yii v1.1](https://github.com/yiisoft/yii).
+
+Yii 2.0 is still under heavy development. We may make significant changes
+without prior notices. **Yii 2.0 is not ready for production use yet.**
+
+[![Build Status](https://secure.travis-ci.org/yiisoft/yii2.png)](http://travis-ci.org/yiisoft/yii2)
+
+This is the yii2-smarty extension.
+
+Installation
+----------------
+The prefered way to install this extension is through [composer](http://getcomposer.org/download/).
+
+Either run
+```
+php composer.phar require yiisoft/yii2-smarty *
+```
+
+or add
+```json
+"yiisoft/yii2-smarty": "*"
+```
+to the require section of your composer.json.
+
+
+*Note: You might have to run `php composer.phar selfupdate`*
+
+
+Usage & Documentation
+-----------
+
+This extension has to be registered prior to usage.
+To enable this view renderer add it to the $rendereres property of your view object.
+
+Example: 
+```php
+<?php
+// config.php
+return array(
+	//....
+	'components' => array(
+		'view' => array(
+			'class' => 'yii\base\View',
+			'viewRenderers' => array(
+				'tpl' => array(
+					'class' => 'yii\smarty\ViewRenderer',
+					//'cachePath' => '@runtime/Smarty/cache',
+				),
+			),
+		),
+	),
+);
+```

-	 * - only: array, list of patterns that the files or directories should match if they want to be returned.
-	 *   A path matches a pattern if it contains the pattern string at its end. For example,
-	 *   '/a/b' will match all files and directories ending with '/a/b'; and the '.svn' will match all files and
-	 *   directories whose name ends with '.svn'. Note, the '/' characters in a pattern matches both '/' and '\'.
-	 *   If a file/directory matches a pattern in both in "only" and "except", it will NOT be returned.
-	 * - except: array, list of patterns that the files or directories should NOT match if they want to be returned.
-	 *   For more details on how to specify the patterns, please refer to the "only" option.
+	 *   The callback can return one of the following values:
+	 *
+	 *   * true: the directory or file will be returned (the "only" and "except" options will be ignored)
+	 *   * false: the directory or file will NOT be returned (the "only" and "except" options will be ignored)
+	 *   * null: the "only" and "except" options will determine whether the directory or file should be returned
+	 *
+	 * - only: array, list of patterns that the file paths should match if they want to be returned.
+	 *   A path matches a pattern if it contains the pattern string at its end.
+	 *   For example, '.php' matches all file paths ending with '.php'.
+	 *   Note, the '/' characters in a pattern matches both '/' and '\' in the paths.
+	 *   If a file path matches a pattern in both "only" and "except", it will NOT be returned.
+	 * - except: array, list of patterns that the file paths or directory paths should match if they want to be excluded from the result.
+	 *   A path matches a pattern if it contains the pattern string at its end.
+	 *   Patterns ending with '/' apply to directory paths only, and patterns not ending with '/'
+	 *   apply to file paths only. For example, '/a/b' matches all file paths ending with '/a/b';
+	 *   and '.svn/' matches directory paths ending with '.svn'. Note, the '/' characters in a pattern matches
+	 *   both '/' and '\' in the paths.
 	 * - recursive: boolean, whether the files under the subdirectories should also be looked for. Defaults to true.
 	 * @return array files found under the directory. The file list is sorted.
