温故知新，微软官方推荐的VisualStudio源代码管理之GitIgnore清单，开启新项目必备宝书

什么是Git Ignore清单

https://git-scm.com/docs/gitignore

简单来说，在Git进行源代码管理中，我们可以通过建立.gitignore来实现一个忽略的黑名单管理，在这个配置文件中被忽略的目录或者文件，发生的任何git变更动作都会被忽略，也不会被Commit和Push到Git Server上。

我们在项目开发过程中，因为编译或者其他原因难免会生成一些不必要的文件，这些文件不是源代码，而是一次性的临时文件，不仅数量巨大，而且没有管理的必要，为了避免源代码管理的混乱和对服务器资源的浪费，我们新建项目的时候，应该及时建立.gitignore文件。

Git初始化

git init

新建Git Ignore清单
