 ## QA
 
-#### 很多框架都自带了 hot reload 的功能，为什么还要单独写个 fileboy 呢？  
+### 很多框架都自带了 hot reload 的功能，为什么还要单独写个 fileboy 呢？  
 
 这个是一款通用的 hot reload 的软件，理论上适用于任何需要 hot reload 的场景，并不局限于语言层面上。只要灵活的配置 `filegirl.yaml`文件就行了。  
 
-#### fileboy 可以应用在那些具体的场景？  
+### fileboy 可以应用在那些具体的场景？  
 
 在开发中，我们很需要一款可以帮助我们自动打包编译的工具，那 fileboy 就非常适合这样的场景。比如 go 项目的热编译，让我们可以边修改代码边运行得到反馈。又比如 PHP Swoole 框架，由于常驻进程的原因，无法更改代码立即reload，使用 fileboy 就可以辅助做到传统 PHP 开发的体验。  
-
 对于一些需要监控文件日志或者配置变动的场景， fileboy 同样适合。你可以事先编写好相应的通知报警脚本，然后定义`filegirl.yaml`中的`command`命令，交由 fileboy 自动运行监控报警。  
 
-#### 通知器在什么时候会发送 http 请求 ?
+### 通知器在什么时候会发送 http 请求 ?
 
 通知器发送 http 通知的前提是在配置文件中设置了 `callUrl` 参数（不为空即为已设置）。触发请求的时机和执行 command 命令是一致的，`command -> delayMillSecond` 参数对于触发器同样有效。请求超时默认15秒.  
 
-#### idea 下更改文件，为什么会执行两次或者多次 command ?
+### idea 下更改文件，为什么会执行两次或者多次 command ?
 
-由于 idea 系列软件特殊的文件保存策略，他会自动创建一些临时文件，并且在需要时多次重写文件，所以有时反映在文件上就是有多次的更改，所以会出现这种情况。1.5版本增加了 `delayMillSecond` 参数，可以解决这个问题。

+### filegirl.yaml 里面的 command 如何配置复杂命令？  
-
-对于“很复杂的命令”这种说法很难去定义，比如 `echo "hello world"`并不复杂，但是对于 fileboy 来讲，目前无法解析这种命令。  
 
 fileboy 目前支持 `命令 + 参数`这种形式的 command，而且 参数中不能有""符号或者有空格。如：  
-
 `go build`:支持；  
-
 `go env`:支持;  
-
 `php swoole start --daemon`:支持  
-
 `cat a.txt | grep "q" | wc -l`:不支持  
-
 对于不支持的命令，可以把它写到一个文件里，然后在 command 中执行这个文件来解决。  
 
-#### 为什么起名为 fileboy，又把配置名叫做 filegirl ？

+Fileboy, File Change Monitoring Notification System, written with Go.  
+For Hot Reload scenarios (typically for developing go projects without having to perform go build manually every time; for example, front-end node packaging) or system monitoring.  
+
+## FEATURES
+
+- Minimalist usage and configuration  
+- Support multiple platforms, Windows/Linux/MacOS  
+- Supports custom file listening scope, listening for specified folders/not listening for specified folders/specified suffix files  
+- Support for custom monitoring events (write / rename / remove / create / chmod)  
+- Support for setting up multiple commands  
+- Command support variable placeholders  
+- Supporting redundant task discarding and customizing redundant task scope  
+- Supporting HTTP notifications  
+- Advanced instruction usage

+## compile
+go build
+## run

+```
+## USAGE
+
+The normal operation of fileboy depends on the `filegirl.yaml` configuration, so for the first time in a project, `filegirl.yaml` needs to be initialized.  
+- Enter the project home directory where you want hot reload;  
+- Running `fileboy init` will generate `filegirl. yaml` files in this directory.  
+- View `filegirl. yaml` and modify it to a configuration item suitable for your project.  
+- Run `fileboy`.  
+  
+If you define the `command-> exec` command, you can run the `fileboy exec` command to confirm whether it can be executed properly in advance. The system will try to run your custom command.  
+You can use `fileboy help` to see help info.
