说起来尴尬，好几年前就搞了github建了仓库，当时玩得还有点6，后来一直的公司都是svn，自己业务项目也没玩，都忘了要怎么提交代码到自己的仓库了。
这边再来一波记录吧。
一、配置用户名
git config --global user.name "Mona Lisa"确认已修改：
git config --global user.name二、本地配置邮箱
git config --global user.email "[email protected]"确认已修改：
git config --global user.email
三、修改github上邮箱，保持一致
https://help.github.com/articles/setting-your-commit-email-address-on-github/
四、https克隆自己的github仓库
本地找个目录用：
git clone url（拷贝的地址）五、修改文件，提交
修改文件，切换到项目根路径下，打开git bash，执行：
git add .git commit -m "Add existing file"git push origin master（这步没让我输密码，不知道为啥）
然后我再去github上，文件已经修改了。
ps：
针对本地项目已经存在，要关联到github仓库的情况：
