Quick setup — if you've done this kind of thing before
We recommend every repository include a README, LICENSE,
and .gitignore.
Create a new repository on the command line
touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/robby0/Java.git
git push -u origin master
Push an existing repository from the command line
git remote add origin https://github.com/robby0/Java.git
git push -u origin master
