Note:
when execute config.sh for environment initilization, 
please use "source config.sh" instead of "./config.sh"

git add .
git commit -m "Codes commit"
git config --global user.email "[email protected]"            
git config --global user.name "yf2009017"
git remote add origin https://github.com/yf2009017/Codes.git
git push -u origin master

If you want to continue making changes and pushing them to GitHub you’ll just need to use the following three commands:
git add .
git commit -m "type your commit message here"
git push origin master


if you have deleted file by then
use git commit -am "Remove useless files"
git push origin master
