Quickbook for Git

开玩笑地说，使用Git这种强大的版本管理工具，时刻要记得一句名言“ Know your place！”

Git Phases

Git 最重要的三个 Phases 的理解对了解当前文件处于哪个工作区十分关键

1. git add 会使当前工作区的更改的文件状态从 unstaged 变成 staged
2. git commit 会使当前工作区的更改的文件状态从 staged 变成 committed

下面的 Flowchart 结合常用命令可以清晰地理解

graph TD;
A[Working Area - unstaged] --> | git add | B[Staging Area - staged];
B --> | git commit | C[ Repo - commited ];
