+# Yii2 AWS S3
+
+An Amazon S3 component for Yii2.
+
+[![License](https://poser.pugx.org/frostealth/yii2-aws-s3/license)](https://github.com/frostealth/yii2-aws-s3/blob/2.x/LICENSE.md)
+[![Latest Stable Version](https://poser.pugx.org/frostealth/yii2-aws-s3/v/stable)](https://packagist.org/packages/frostealth/yii2-aws-s3)
+[![Total Downloads](https://poser.pugx.org/frostealth/yii2-aws-s3/downloads)](https://packagist.org/packages/frostealth/yii2-aws-s3)
+[![Latest Unstable Version](https://poser.pugx.org/frostealth/yii2-aws-s3/v/unstable)](https://packagist.org/packages/frostealth/yii2-aws-s3)
+
+## Installation
+
+1. Run the [Composer](http://getcomposer.org/download/) command to install the latest stable version:
+
+    ```bash
+    composer require frostealth/yii2-aws-s3 ~2.0@stable
+    ```
+
+2. Add the component to `config/main.php`
+
+    ```php
+    'components' => [
+        // ...
+        's3' => [
+            'class' => 'frostealth\yii2\aws\s3\Service',
+            'credentials' => [ // Aws\Credentials\CredentialsInterface|array|callable
+                'key' => 'my-key',
+                'secret' => 'my-secret',
+            ],
+            'region' => 'my-region',
+            'defaultBucket' => 'my-bucket',
+            'defaultAcl' => 'public-read',
+        ],
+        // ...
+    ],
+    ```
+
+## Basic usage
+
+### Usage the command factory and additional params
+
+```php
+/** @var \frostealth\yii2\aws\s3\Service $s3 */
+$s3 = Yii::$app->get('s3');
+
+/** @var \Aws\ResultInterface $result */
+$result = $s3->commands()->get('filename.ext')->saveAs('/path/to/local/file.ext')->execute();
+
+$result = $s3->commands()->put('filename.ext', 'body')->setContentType('text/plain')->execute();
+
+$result = $s3->commands()->delete('filename.ext')->execute();
+
+$result = $s3->commands()->upload('filename.ext', '/path/to/local/file.ext')->setAcl('private')->execute();
+
+$result = $s3->commands()->restore('filename.ext', $days = 7)->execute();
+
+$isExisting = $s3->commands()->exist('filename.ext')->execute();
+
+$url = $s3->commands()->getUrl('filename.ext')->execute();
+
+$signedUrl = $s3->commands()->getPresignedUrl('filename.ext', '+2 days')->execute();
+```
+
+### Short syntax
+
+```php
+/** @var \frostealth\yii2\aws\s3\Service $s3 */
+$s3 = Yii::$app->get('s3');
+
+/** @var \Aws\ResultInterface $result */
+$result = $s3->get('filename.ext');
+
+$result = $s3->put('filename.ext', 'body');
+
+$result = $s3->delete('filename.ext');
+
+$result = $s3->upload('filename.ext', '/path/to/local/file.ext');
+
+$result = $s3->restore('filename.ext', $days = 7);
+
+$isExisting = $s3->exist('filename.ext');
+
+$url = $s3->getUrl('filename.ext');
+
+$signedUrl = $s3->getPresignedUrl('filename.ext', '+2 days');
+```
+
+### Asynchronous execution
+
+```php
+/** @var \frostealth\yii2\aws\s3\Service $s3 */
+$s3 = Yii::$app->get('s3');
+
+/** @var \GuzzleHttp\Promise\PromiseInterface $promise */
+$promise = $s3->commands()->get('filename.ext')->async()->execute();
+
+$promise = $s3->commands()->put('filename.ext', 'body')->async()->execute();
+
+$promise = $s3->commands()->delete('filename.ext')->async()->execute();
+
+$promise = $s3->commands()->upload('filename.ext', 'source')->async()->execute();
