打算用LyX进行latex学习和使用。
NOTE: Before you install LyX on Windows, you need to install a TeX distribution. For more information on how to do this, please see this page on the LyX wiki.
在安装LyX之前要安装Tex，我选择安装网页里推荐的TexLive
安装过程真的好慢，我从下午开始，第二天早上安装好，因为要一个一个包联网安装，所以电脑还不能断网，不能关。

最后大概是这样的，然后就安装成功了Tex
接下来安装LyX
没有中文选项……无所谓，默认安装里面包含我需要的English(GB)，而且之前也安装了Tex Live，C盘空间也够，就一路next。
新建文件
啥也没选也自动中文了，不过上面的图标怎么这么小
安装完成！配置后面有学到的再记录。
