-- scan mini program
+- 微信小程序扫描 + 解密 + 解包
+  > 不指定参数的话，会在默认安装目录扫描小程序 wxid，然后获取小程序信息（需要网络）
+
+  键盘上下键选中想要处理的小程序，然后按回车
 
     ```bash
-    # wxapkg.exe scan --help
     wxapkg.exe scan
     ```
 
-- unpack mini program
-
-    ```bash
-    # wxapkg.exe unpack --help     
+- 单独解密 + 解包指定的微信小程序
+  > 指定小程序路径，自动获取 wxid 然后解密解包
+    ```bash     
     wxapkg.exe unpack -o out-dir -r "%USERPROFILE%\Documents\WeChat Files\Applet\wx00000000000000"
     ```
 
-**Install:**
+**⚒️ 安装**
 
-Download the latest [release](https://github.com/wux1an/wxapkg/releases/latest) or build with `go install` by yourself
+下载最新的发布版本 [release](https://github.com/wux1an/wxapkg/releases/latest)，或者用下面的命令自己编译
 
 ```
 go install github.com/wux1an/wxapkg@latest
 ```
 
-**Todo:**
+**📝 其他功能**
 
-- [x] scan more information (need networking）
-- [x] json beautify
-- [x] javascript beautify
-- [x] html beautify
-- [ ] auto export uri in files
+- [x] 获取小程序信息（需要网络连接）
+- [x] 代码美化，默认开启，可以使用 `--disable-beautify` 参数禁用
+    - [x] 美化 `JSON` 文件
+    - [x] 美化 `JavaScript` 文件（会有点慢）
+    - [x] 美化 `Html` 文件，包括其中的 `<script>` 标签（会有点慢）
+- [ ] 自动导出文件中的敏感 url 和 key 等信息
