作为一个合格的程序员，通过编程实现某项功能是一项必须的技能，除此之外，文档的撰写功能也是非常重要的。那么问题来了，在写文档的时候你用什么工具来撰写呢？Word虽然是个非常棒的办公软件，但是当你要在Word里面插入优雅的代码段落是很困难的，如果你在Word里面插入代码，那最后很有可能就会变成格式全无的一段段文本文字了，毫无阅读感，除非你可以把某种语言中的关键词，函数，符号等使用不同的颜色标注出来，如此才具有比较高的阅读性。
图1 把代码粘贴进Word
如果大家曾经下载过Github或者Gitee上面某个开源的项目代码时，是否发现其底下的Doc或者Docoument文件夹底下存放了一些以.md为后缀名的文件，如图2所示。
图2 开源项目doc文件夹下的`.md`文件
然后，当我们尝试着去打开这些文件的时候，我们内心千万头xxx跑过，这些说明文档哪是给人阅读的？明明好好的文字中，为什么要加上一些乱七八糟的符号，看着像代码，仔细看又不像代码。
图3 记事本打开`.md`文件
程序员们虽然有些为了彰显自己的智商，确实比较务虚，但是还不至于在文档上添加这些无用的信息，那么到底是什么原因导致这些文档没法正常阅读呢？其实最主要的原因是你打开方式不对。
这种以.md格式结尾的文档其实叫做”Markdown“文件。
Markdown 是一种轻量级标记语言，它允许人们使用易读易写的纯文本格式编写文档。
Markdown 语言在 2004 由约翰·格鲁伯（英语：John Gruber）创建。
Markdown 编写的文档可以导出 HTML 、Word、图像、PDF、Epub 等多种格式的文档。
Markdown 编写的文档后缀为 .md, .markdown。
阅读了上面的的内容，我们知道，Markdown其实是一种标记语言，我们平时所说的HTML其实也是一种标记语言，只不过Markdown标记语言比HTML简单很多。那么既然它是一种标记语言，因此需要有特定的阅读工具来解释这些标记。
Markdown的标记语言编写和阅读工具有很多，其中最方便和最好用的就是我写这篇文档所用的Typora。
接下来我们就使用 Typora软件来打开刚刚上面的那份文档，如图4所示。
图4 美观的Markdown
使用Markdown打开的文档，我们能看出它是多么美观，这才是它的真面目。
但是此时可能有人会说了，如果要使用Word来写出上面风格的文档，也不是什么难事。那如果要使用Word来写出如下样式的文档呢？
