在github上 新建一个项目后，并且未提交任何代码，会有一个页面提示我们如何快速部署。在此备份一下那个页面
Quick setup — if you’ve done this kind of thing before
Set up in Desktop or https://github.com/jiashubing/crawler4j-demo.git
We recommend every repository include a README, LICENSE, and .gitignore.
…or create a new repository on the command line
echo "# crawler4j-demo" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/jiashubing/crawler4j-demo.git
git push -u origin master
…or push an existing repository from the command line
git remote add origin https://github.com/jiashubing/crawler4j-demo.git
git push -u origin master
…or import code from another repository
You can initialize this repository with code from a Subversion, Mercurial, or TFS project.
