 In order to use formatters you need to install and enable [intl](http://www.php.net/manual/en/intro.intl.php) PHP
 extension.
 
+Examples
+--------
+
+###Translating module messages
+
+If you want to translate messages for a module and avoid using a single translation file for all messages, you can make it like the following:
+
+```php
+<?php
+
+namespace app\modules\users;
+
+use Yii;
+
+class Module extends \yii\base\Module
+{
+	public $controllerNamespace = 'app\modules\users\controllers';
+
+	public function init()
+	{
+		parent::init();
+		$this->registerTranslations();
+	}
+
+	public function registerTranslations()
+	{
+		Yii::$app->i18n->translations['modules/users/*'] = [
+			'class' => 'yii\i18n\PhpMessageSource',
+			'sourceLanguage' => 'en',
+			'basePath' => '@app/modules/users/messages',
+			'fileMap' => [
+				'modules/users/validation' => 'validation.php',
+				'modules/users/form' => 'form.php',
+				...
+			],
+		];
+	}
+
+	public static function t($category, $message, $params = [], $language = null)
+	{
+		return Yii::t('modules/users/' . $category, $message, $params, $language);
+	}
+
+}
+```
+
+In the example above we are using wildcard for matching and then filtering each category per needed file.
+
+###Translating widgets messages
+
+Same rules can be applied for widgets too, for example:
+
+```php
+<?php
+
+namespace app\widgets\menu;
+
+use yii\base\Widget;
+use Yii;
+
+class Menu extends Widget
+{
+
+	public function init()
+	{
+		parent::init();
+		$this->registerTranslations();
+	}
+
+	public function registerTranslations()
+	{
+		$i18n = Yii::$app->i18n;
+		$i18n->translations['widgets/menu/*'] = [
+			'class' => 'yii\i18n\PhpMessageSource',
+			'sourceLanguage' => 'en',
+			'basePath' => '@app/widgets/menu/messages',
+			'fileMap' => [
+				'widgets/menu/messages' => 'messages.php',
+			],
+		];
+	}
+
+	public function run()
+	{
+		echo $this->render('index');
+	}
+
+	public static function t($category, $message, $params = [], $language = null)
+	{
+		return Yii::t('widgets/menu/' . $category, $message, $params, $language);
+	}
+
+}
+```
+
+> **Note**: For widgets you also can use i18n views, same rules as for controllers are applied to them too.

+Customizing application config
+------------------------------
+
+You may need to specify different configuration files per test cases, to do this you can make it like the following:
+
 ```php
 <?php
 
 SomeConsoleTest extends \yii\codeception\TestCase
 {
 	// this is the config file to load as application config
-	public static $applicationConfig = '@app/config/web.php';
-
-	// this defines the application class to use for mock applications
-	protected $applicationClass = 'yii\web\Application';
+	public $appConfig = '@app/path/to/my/custom/config/for/test.php';
 }
 ```
 
-The `$applicationConfig` property may be set for all tests in a `_bootstrap.php` file like this:
+The `$appConfig` property could be an array or a valid alias, pointing to the file that returns a config array. You can specify
+application class in the config, for example for testing console commands or features you can create `_console.php` config under
+`tests/unit` directory like this:
 
 ```php
-<?php
-
-yii\codeception\TestCase::$applicationConfig = yii\helpers\ArrayHelper::merge(
-	require(__DIR__ . '/../../config/web.php'),
-	require(__DIR__ . '/../../config/codeception/unit.php')
+return yii\helpers\ArrayHelper::merge(
+	require(__DIR__ . '/../../config/console.php'),
+	require(__DIR__ . '/../_config.php'),
+	[
+		'class' => 'yii\console\Application',
+		'components' => [
+			//override console components if needed
+		],
+	]
 );
 ```
 
-Don't forget that you have to include autoload and Yii class in the `_bootstrap.php` file.
+and then just use your `ConsoleTestCase` like the following:
+
+```php
 
-You also can reconfigure some components for tests, for this purpose there is a `$config` property in the `TestCase` class.
+use \yii\codeception\TestCase;
+
+class ConsoleTestCase extends TestCase
+{
+	public $appConfig = '@tests/unit/_console.php';
+}
+```
+
+You can extend other console test cases from this basic `ConsoleTestCase`.
+
+Reconfiguring components for testing
+------------------------------------
+
+You can reconfigure a component for testing, for this purpose in your `setUp` method of your test case 
+you can do this for example:
 
 ```php
 <?php
 
-SomeOtherTest extends \yii\codeception\TestCase
+use \yii\codeception\TestCase;
+use Yii;
+
+class MailTest extends TestCase
 {
-	public $config = [
-		'components' => [
-			'mail' => [
-				'useFileTransport' => true,
+
+	protected function setUp()
+	{
+		// don't forget to call parent method that will setup Yii application
+		parent::setUp();
+
+		Yii::$app->mail->fileTransportCallback = function ($mailer, $message) {
+			return 'testing_message.eml';
+		};
+	}
+
+}
+```
+
+You don't need to worry about application instances and isolation because application will be created [each time](https://github.com/yiisoft/yii2/blob/master/extensions/codeception/TestCase.php#L31) before any of test method will be executed in test case.
+You can mock application in a different way. For this purposes you have method [`mockApplication`](https://github.com/yiisoft/yii2/blob/master/extensions/codeception/TestCase.php#L55) available in your test case.
+This method creates new application instance and replaces old one with it and is handy when you need to create application with a config that is different from other test methods in the current test suite. For example:
+
+```php
+
+use \yii\codeception\TestCase;
+
+class SomeMyTest extends TestCase
+{
+
+	public function testOne()
+	{
+		...
+	}
+
+	public function testTwo()
+	{
+		$this->mockApplication([
+			'language' => 'ru-RU',
+			'components' => [
+				'db' => [
+					//your custom configuration here
+				],
 			],
-		]
-	];
+		]);
+
+		//your expectations and assertions goes here
+	}
+
+	public function testThree()
+	{
+		...
+	}
+
 }
 ```
 
+Additional debug output
+-----------------------
+
 Because of Codeception buffers all output you can't make simple `var_dump()` in the TestCase, instead you need to use
 `Codeception\Util\Debug::debug()` function and then run test with `--debug` key, for example:
