Git 全局设置（必须）:

git config --global user.name "kenvie"
git config --global user.email "7097341@qq.com"

创建 git 仓库:

mkdir [folder]   //建立一个仓库（文件夹）
cd [folder]      //进入创建的这个仓库（文件夹）
git init         //初始化这个仓库（文件夹）

#修改或者添加文件
git add .
git commit -m first_commit
git remote add origin 项目git   //https://xxx.com/xxx/xxx.git 格式
git push -u origin master

已有仓库?

cd [folder]
git remote add origin 项目git   //https://xxx.com/xxx/xxx.git 格式
git push -u origin master

演示例子：

#1、在目录中git下vue-element-admin这个仓库，git下来会把源码放在以项目名命名的文件夹里
D:\Project>git clone https://gitee.com/kenvie/vue-element-admin.git

#2、进入这个项目地址
D:\Project>cd vue-element-admin

-----------------------在这中间可以添加、修改文件-----------------------

#3、这句我理解的意思就是将目录中的文件添加到暂存区
D:\Project\vue-element-admin>git add .

#4、将暂存区里的改动给提交到本地的版本库
D:\Project\vue-element-admin>git commit -m 修订README.md
[master 5746f0d] 修订README.md
 1 file changed, 1 insertion(+), 2 deletions(-)

#5、我理解的是关联远程git仓库
D:\Project\vue-element-admin>git remote add origin https://gitee.com/kenvie/vue-element-admin.git
fatal: remote origin already exists.

#6、同步本地和远程仓库
D:\Project\vue-element-admin>git push -u origin master
