先新建一个文件夹用于存储项目，在Git Bash中进入该文件夹
$ cd E:/operation/new
将要更改的github中的picture项目用git clone克隆下来
$ git clone https://github.com/shmily07/picture

用pwd显示当前路径
$ pwd
/e/operation/new
进入picture项目
$ cd picture
ls查看当前picture项目中含有的文件
$ ls
README.md test/ test.jpg
- 此时picture下有 README.md 和 test.jpg两个文件
- 通过vim修改文件（若无则新建或修改）
$ vim README.md
若要保存修改与退出，需持续按Esc键，再输入：wq
若要强行退出则持续按Esc键，再连续按两次大写 Z 。
用add将修改的文件放入缓存区
$ git add README.md
输入 commit -m“”将文件传到仓库（双引号里面是说明）
$ git commit -m "提交"
最后 push一下就好啦
$ git push
