1、新建一个文件夹如：HelloDemo
2、文件夹下创建一个空白文档如：a.txt（我创建了个README.md添加不上，可能默认屏蔽了）
3、在文件夹内右键打开git命令窗口（Git Bash Here）
4、连接远程仓库：git remote add origin 仓库地址（例如：git remote add origin https://gitee.com/ling195/hello-demo.git）
5、添加本地空白文件：git add a.txt
6、提交本地空白文件：git commit -m 'first commit'
7、推送本地空白文件：git push origin master
8、仓库初始化成功，以下是命令场景
