Putting your existing work on GitHub can let you share and collaborate in lots of great ways.
If you are migrating your project from CodePlex, read the migration guide for more information.
Tip: If you're most comfortable with a point-and-click user interface, try adding your project with GitHub Desktop. For more information, see "Adding a repository from your local computer to GitHub Desktop" in the GitHub Desktop Help.
