Yeap, you've now put your code under Version Control.
I Strongly recommend, if you are new to Git, to take this Quick Curse to learning Git -> Got 15 minutes and want to learn Git?
If you commit to Github you may set your configs
$ git config --global user.name "Your Name" # Set your Git name
$ git config --global user.email youremail@gmail.com # Set your Git email
Set your Code under Version Conroll
$ git init # Set up Git on your project
$ git status # See tracked, untracked, and staged files
$ git add . # Add new files to Git
$ git commit -am "Initial commit" # Save your project files to Git
Commit to GitHub
$ git remote add origin git@github.com:yourusername/yours.git # Set up git to push to your Github repository
$ git push -u origin master # Push your code to Github (sets the upstream the first time)
$ git push # Push your code to Github
