+##### 说明
+
+本扩展为yangyifan/upload的分支，仅为解决在开发过这种遇到的问题：
+* 原扩展没有release版本，导致开发时composer.json未设置"minimum-stability": "dev"时候，不能正常安装的问题，即便设置了 "minimum-stability": "dev"，直接使用composer update时会使其他依赖包也强制更新到了dev-master版本，带来不稳定因素。
+
+
+##### 安装
+
+* composer require "ikodota/upload" 。
+* 添加 UploadServiceProvider 到您项目 config/app.php 中的 providers 部分: Yangyifan\Upload\UploadServiceProvider。
+* 支持七牛，upyun，oss。
+* 完成按照官方 ``` Storage  ``` 来扩展。所以不需要修改代码，只需要新增配置文件信息，就可以替换任何一种存储引擎。
+
+###### 开始
+
+*  use Storage
+
+```
+use Storage;
+```
+
+* 示例代码
+
+```
+
+        $image  = "11/22/33/7125_yangxiansen.jpg";
+        $image2 = "111.png";
+        $image3 = "2.txt";
+
+        $drive = \Storage::drive('oss');                                                            //选择oss上传引擎
+
+        dump($drive->getMetadata($image2));                                                         //判断文件是否存在

+        dump($drive->rename($image3, '4.txt/'));                                                    //重命名文件
