-升级过程并不复杂，但也简单粗暴，总共分为三个步骤。
+升级过程并不复杂，但也简单粗暴，总共分为四个步骤。
 1. [下载](https://github.com/wisp-x/lsky-pro/releases)最新版程序并解压到本地。
-2. 将旧版程序 ```config/db.php``` 文件复制到新版程序的 ```config``` 文件夹，如果你使用的是本地储存策略，文件是储存在本地的，请注意也要将你旧版本的图片资源移动到新程序对应的目录。
-3. 删除旧版本程序所有文件，上传最新版程序到站点根目录即可(这一步也可以直接覆盖，但会有残留文件，不选择覆盖的话建议先打包备份旧版本)。
