Adding the project of Google app engine to GitHub
cd to the directory that you want to push into github
echo "# MyBlog" >> README.md
git init
git add README.md
git commit -m "first commit"
It may ask for self-identity
# Set a Git username:
$ git config --global user.name "myName"
# Confirm that you have set the Git username correctly:
$ git config --global user.name
> myName
It may need your username and password of github
$ git remote add origin "remote repository URL"
# Sets the new remote
$ git remote -v
# Verifies the new remote URL
$ git push -u origin master
# Pushes the changes in your local repository up to the remote repository you specified as the origin
当我们更改了github上的内容之后，我们登录到Google cloud，再把这些更新同步下来：
$ git pull origin master
# 意思是我们从origin pull 下来，和本地的master branch合并
Test the application
$ dev_appserver.py app.yaml
Deploy your app
