故事背景：很多时候对外发布的产品需要一份html格式的文档
首先要了解的是 word直接转成html是不现实的，需要通过md文件来转换。
我们本节课讨论的Gitbook即是在MD基础上进行操作的。
所以
任务一：安装typora软件，用于编辑md文件，简单自学一下即可掌握
任务二：全局安装gitbook
npm install -g gitbook-cli任务三：打开当前目录，执行
$ gitbook init你会看到两个文件，README.md 和 SUMMARY.md
将SUMMARY.md 文件拖入typora进行编辑
# 目录* [前言](README.md)
* [第一章](one/README.md)* [1](one/one.md)* [2](one/two.md)* [3](one/three.md)
* [第二章](two/README.md)
* [第三章](three/README.md)然后保存编辑，再次执行gitbook init，gitbook会根据这个summary文件内的结构创建相应的文件。
任务四：运行
$ gitbook serve然后可以根据提示在本地查看运行效果
任务五：生成html
$ gitbook build执行后会在_book目录下生成我们需要的html文件，那么剩下的工作量其实就是维护md，这里建议使用git
拓展：
这里要补充两点
第一： gitbook社区拥有很多插件，我们可以通过gitbook install命令来安装，需要我们创建一个book.json文件，我自己使用的这份json文件可以用来参考

}第二：我们的gitbook还拥有生成pdf epub mobi格式的功能，但是经过试验，效果不太好，暂时不推荐
来看一下最终效果
