 # monit-via-herounion
 
-Website monitor via HeroUnion.
\ No newline at end of file
+Website monitor via HeroUnion.
+基于HeroUnion的网站监控程序。
+
+
+## 使用方法
+
+1. 下载源码：
+```
+git clone "https://git.filesite.io/filesite/monit-via-herounion.git"
+```
+
+2. 安装node依赖包
+```
+npm install
+```
+
+3. 配置需要监控的网站
+
+修改文件：conf/config.json
+
+在**monit_urls**里添加网址，例如：
+```
+"https://tajian.tv",
+"https://filesite.io"
+```
+
+4. 启动监控程序
+```
+npm start
+```
+
+
+## 查看监控结果
+
+在log/目录下会生成两个日志文件：
+
+* ok.log 	- 成功访问日志
+* fail.log 	- 访问失败日志
+
+
+## HeroUnion账号获取
+
+请打开网站，查看底部的联系方式：
+[FileSite.io](https://filesite.io)
