git的 init、push、import的简单使用

有时候刚创建一个仓库，总是不记得命令，就做个笔记

create a new repository on the command line
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/Xanthuim/nodejs_express_sample.git
git push -u origin master

push an existing repository from the command line

git remote add origin https://github.com/Xanthuim/nodejs_express_sample.git
git push -u origin master

import code from another repository
You can initialize this repository with code from a Subversion, Mercurial, or TFS project.
