docs/guide/assets.md

+Managing assets
+===============
+
+An asset in Yii is a file that is included into the page. It could be CSS, JavaScript or
+any other file. Framework provides many ways to work with assets from basics such as adding `<script src="` tag
+for a file that is [handled by View](view.md) section to advanced usage such as pusblishing files that are not
+under webserve document root, resolving JavaScript dependencies or minifying CSS.
+
+Declaring asset bundle
+----------------------
+
+In order to publish some assets you should declare an asset bundle first. The bundle defines a set of asset files or
+directories to be published and their dependencies on other asset bundles.
+
+Both basic and advanced application templates contain `AppAsset` asset bundle class that defines assets required
+applicationwide. Let's review basic application asset bundle class:
+
+```php
+class AppAsset extends AssetBundle
+{
+	public $basePath = '@webroot';
+	public $baseUrl = '@web';
+	public $css = [
+		'css/site.css',
+	];
+	public $js = [
+	];
+	public $depends = [
+		'yii\web\YiiAsset',
+		'yii\bootstrap\BootstrapAsset',
+	];
+}
+```
+
+In the above `$basePath` specifies web-accessible directory assets are served from. It is a base for relative
+`$css` and `$js` paths i.e. `@webroot/css/site.css` for `css/site.css`. Here `@webroot` is an alias that points to
+application's `web` directory.
+
+`$baseUrl` is used to specify base URL for the same relative `$css` and `$js` i.e. `@web/css/site.css` where `@web`
+is an alias that corresponds to your website base URL such as `http://example.com/`.
+
+In case you have asset files under non web accessible directory, that is the case for any extension, you need
+to additionally specify `$sourcePath`. Files will be copied or symlinked from source bath to base path prior to being
+registered. In case source path is used `baseUrl` is generated automatically at the time of publising asset bundle.
+
+Dependencies on other asset bundles are specified via `$depends` property. It is an array that contains fully qualified
+names of bundle classes that should be published in order for this bundle to work properly.
+
+Here `yii\web\YiiAsset` adds Yii's JavaScript library while `yii\bootstrap\BootstrapAsset` includes
+[Bootstrap](http://getbootstrap.com) frontend framework.
+
+Asset bundles are regular classes so if you need to define another one, just create alike class with unique name. This
+class can be placed anywhere but the convention for it is to be under `assets` directory of the applicaiton.
+
+Registering asset bundle
+------------------------
+
+Asset bundle classes are typically registered in views or, if it's main application asset, in layout. Doing it is
+as simple as:
+
+```php
+use app\assets\AppAsset;
+AppAsset::register($this);
+```
+
+Since we're in a view context `$this` refers to `View` class.
+
+Overriding asset bundles
+------------------------
+
+Sometimes you need to override some asset bundles application wide. A good example is loading jQuery from CDN instead
+of your own server. In order to do it we need to configure `assetManager` application component via config file. In case
+of basic application it is `config/web.php`:
+
+```php
+return [
+    // ...
+    'components' => [
+        'assetManager' => [
+            'bundles' => [
+                'yii\web\JqueryAsset' => [
+                     'sourcePath' => null,
+                     'js' => ['//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js']
+                ],
+            ],
+        ],
+    ],
+];
+```
+
+In the above we're adding asset bundle definitions to `bunldes` property of asset manager. Keys there are fully
+qualified class paths to asset bundle classes we want to override while values are key-value arrays of class properties
+and corresponding values to set.
+
+Setting `sourcePath` to `null` tells asset manager not to copy anything while `js` overrides local files with a link
+to CDN.
+
+Enabling symlinks
+-----------------
+
+Asset manager is able to use symlinks instead of copying files. It is turned off by default since symlinks are often
+disabled on shared hosting. If your hosting environment supports symlinks you certainly should enable the feature via
+application config:
+
+```php
+return [
+    // ...
+    'components' => [
+        'assetManager' => [
+            'linkAssets' => true,
+        ],
+    ],
+];
+```
+
+There are two main benefits in enabling it. First it is faster since no copying is required and second is that assets
+will always be up to date with source files.

docs/guide/basics.md

+Basic concepts of Yii
+=====================
+
+
+Component and Object
+--------------------
+
+Classes of the Yii framework usually extend from one of the two base classes [[Object]] and [[Component]].
+These classes provide useful features that are added automatically to all classes extending from them.
+
+The `Object` class provides the [configuration and property feature](../api/base/Object.md).
+The `Component` class extends from `Object` and adds [event handling](events.md) and [behaviors](behaviors.md).
+
+`Object` is usually used for classes that represent basic data structures while `Component` is used for
+application components and other classes that implement higher logic.
+
+
+Object Configuration
+--------------------
+
+The [[Object]] class introduces a uniform way of configuring objects. Any descendant class
+of [[Object]] should declare its constructor (if needed) in the following way so that
+it can be properly configured:
+
+```php
+class MyClass extends \yii\base\Object
+{
+    public function __construct($param1, $param2, $config = [])
+    {
+        // ... initialization before configuration is applied
+
+        parent::__construct($config);
+    }
+
+    public function init()
+    {
+        parent::init();
+
+        // ... initialization after configuration is applied
+    }
+}
+```
+
+In the above, the last parameter of the constructor must take a configuration array
+which contains name-value pairs for initializing the properties at the end of the constructor.
+You can override the `init()` method to do initialization work that should be done after
+the configuration is applied.
+
+By following this convention, you will be able to create and configure a new object
+using a configuration array like the following:
+
+```php
+$object = Yii::createObject([
+    'class' => 'MyClass',
+    'property1' => 'abc',
+    'property2' => 'cde',
+], $param1, $param2);
+```
+
+
+Path Aliases
+------------
+
+Yii 2.0 expands the usage of path aliases to both file/directory paths and URLs. An alias
+must start with a `@` character so that it can be differentiated from file/directory paths and URLs.
+For example, the alias `@yii` refers to the Yii installation directory. Path aliases are
+supported in most places in the Yii core code. For example, `FileCache::cachePath` can take
+both a path alias and a normal directory path.
+
+Path alias is also closely related with class namespaces. It is recommended that a path
+alias be defined for each root namespace so that you can use Yii the class autoloader without
+any further configuration. For example, because `@yii` refers to the Yii installation directory,
+a class like `yii\web\Request` can be autoloaded by Yii. If you use a third party library
+such as Zend Framework, you may define a path alias `@Zend` which refers to its installation
+directory and Yii will be able to autoload any class in this library.

+            'errorAction' => 'site/error',
+    ],
+```
+
+After it is done in case of error Yii will launch `SiteController::actionError()`. Since errors are converted to
+exceptions we can get exception from error handler:
+
+```php
+public function actionError()
+{
+    $exception = \Yii::$app->getErrorHandler()->exception;
+    $this->render('myerror', ['message' => $exception->getMessage()]);
+}
+```
+
+Since most of the time you need to adjust look and feel only, Yii provides `ErrorAction` class that can be used in
+controller instead of implementing action yourself:
+
+```php
+public function actions()
+{
+    return [
+        'error' => [
+            'class' => 'yii\web\ErrorAction',
+        ],
+    ];
+}
+```
+
+After defining `actions` in `SiteController` as shown above you can create `views/site/error.php`. In the view there
+are three varialbes available:
+
+- `$name`: the error name
+- `$message`: the error message
+- `$exception`: the exception being handled
+

docs/guide/events.md

+Events
+======
+
+TBD, see also [Component.md](../api/base/Component.md).
+
+There is no longer the need to define an `on`-method in order to define an event in Yii 2.0.
+Instead, you can use whatever event names. To attach a handler to an event, you should
+use the `on` method now:
+
+```php
+$component->on($eventName, $handler);
+// To detach the handler, use:
+// $component->off($eventName, $handler);
+```
+
+
+When you attach a handler, you can now associate it with some parameters which can be later
+accessed via the event parameter by the handler:
+
+```php
+$component->on($eventName, $handler, $params);
+```
+
+
+Because of this change, you can now use "global" events. Simply trigger and attach handlers to
+an event of the application instance:
+
+```php
+Yii::$app->on($eventName, $handler);
+....
+// this will trigger the event and cause $handler to be invoked.
+Yii::$app->trigger($eventName);
+```
+
+If you need to handle all instances of a class instead of the object you can attach a handler like the following:
+
+```php
+Event::on(ActiveRecord::className(), ActiveRecord::EVENT_AFTER_INSERT, function ($event) {
+	Yii::trace(get_class($event->sender) . ' is inserted.');
+});
+```
+
+The code above defines a handler that will be triggered for every Active Record object's `EVENT_AFTER_INSERT` event.

 Working with forms
 ==================
 
-The primary way of using forms in Yii is through [[\yii\widgets\ActiveForm]]. This approach should be preferred when the form is based upon  a model. Additionally, there are some useful methods in [[\yii\helpers\Html]] that are typically used for adding buttons and help text to any form.

 When creating model-based forms, the first step is to define the model itself. The model can be either based upon the Active Record class, or the more generic Model class. For this login example, a generic model will be used:
