+MongoDb Extension for Yii 2
+===========================
+
+Out of the box, Yii includes support for the [Bootstrap 3](http://getbootstrap.com/) markup and components framework
+(also known as "Twitter Bootstrap"). Bootstrap is an excellent, responsive framework that can greatly speed up the
+client-side of your development process.
+
+The core of Bootstrap is represented by two parts:
+
+- CSS basics, such as a grid layout system, typography, helper classes, and responsive utilities.
+- Ready to use components, such as forms, menus, pagination, modal boxes, tabs etc.

+Basic Usage
+===========
+
+Yii doesn't wrap the bootstrap basics into PHP code since HTML is very simple by itself in this case. You can find details
+about using the basics at [bootstrap documentation website](http://getbootstrap.com/css/). Still Yii provides a
+convenient way to include bootstrap assets in your pages with a single line added to `AppAsset.php` located in your
+`@app/assets` directory:
+
+```php
+public $depends = [
+    'yii\web\YiiAsset',
+    'yii\bootstrap\BootstrapAsset', // this line
+];
+```
+
+Using bootstrap through Yii asset manager allows you to minimize its resources and combine with your own resources when
+needed.

docs/guide/installation.md

+Installation
+============
+
+## Getting Composer package
+
+The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
+
+Either run
+
+```
+php composer.phar require --prefer-dist yiisoft/yii2-bootstrap
+```
+
+or add
+
+```
+"yiisoft/yii2-bootstrap": "~2.0.0"
+```
+
+to the require section of your `composer.json` file.

docs/guide/topics-less.md

+Using the .less files of Bootstrap directly
+===========================================
+
+If you want to include the [Bootstrap css directly in your less files](http://getbootstrap.com/getting-started/#customizing)
+you may need to disable the original bootstrap css files to be loaded.
+You can do this by setting the css property of the [[yii\bootstrap\BootstrapAsset|BootstrapAsset]] to be empty.
+For this you need to configure the `assetManager` [application component](structure-application-components.md) as follows:
+
+```php
+    'assetManager' => [
+        'bundles' => [
+            'yii\bootstrap\BootstrapAsset' => [
+                'css' => [],
+            ]
+        ]
+    ]
+```

docs/guide/usage-widgets.md

+Yii widgets
+===========
+
+Most complex bootstrap components are wrapped into Yii widgets to allow more robust syntax and integrate with
+framework features. All widgets belong to `\yii\bootstrap` namespace:
+
+- [[yii\bootstrap\ActiveForm|ActiveForm]]
+- [[yii\bootstrap\Alert|Alert]]
+- [[yii\bootstrap\Button|Button]]
+- [[yii\bootstrap\ButtonDropdown|ButtonDropdown]]
+- [[yii\bootstrap\ButtonGroup|ButtonGroup]]
+- [[yii\bootstrap\Carousel|Carousel]]
+- [[yii\bootstrap\Collapse|Collapse]]
+- [[yii\bootstrap\Dropdown|Dropdown]]
+- [[yii\bootstrap\Modal|Modal]]
+- [[yii\bootstrap\Nav|Nav]]
+- [[yii\bootstrap\NavBar|NavBar]]
+- [[yii\bootstrap\Progress|Progress]]
+- [[yii\bootstrap\Tabs|Tabs]]
