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
