If you want to import a Git repository that is stored on a code hosting service that is publicly available on the internet, we recommend using GitHub Importer. For more information, see "Using GitHub Importer."
If your source code is not tracked by Git or is not publicly available, you can use the command line instead.
To import a Git repository that is stored on a code hosting service that is not accessible from the public internet, see "Importing an external Git repository using the command line."
To import code that is only stored locally, and is either tracked by Git or not tracked by any version control system, see "Adding locally hosted code to GitHub."
To import code that is tracked by any version control system other than Git, first convert the repository to Git, then push the Git repository to GitHub.
All of these tools import source code and revision history, only. If you also want to import your settings and your collaboration history, such as issues and pull requests, you'll need to use more advanced tools. To determine the best tool to use for your migration, see "Planning your migration to GitHub."
