GitHub AE is currently under limited release.

Importing an external Git repository using the command line

If your source code is tracked in a Git repository, you can import the repository using Git on the command line.

Before you start, make sure you know:

  • Your GitHub AE username
  • The clone URL for the external repository, such as or git:// (perhaps with a user@ in front of the domain name)

For purposes of demonstration, we'll use:

  • An external account named extuser
  • An external Git host named
  • A GitHub AE personal account named ghuser
  • A repository on GitHub AE named repo.git
  1. Create a new repository on GitHub AE. You'll import your external Git repository to this new repository.
  2. On the command line, make a "bare" clone of the external repository using the external clone URL. This creates a full copy of the data, but without a working directory for editing files, and ensures a clean, fresh export of all the old data.
    $ git clone --bare
    # Makes a bare clone of the external repository in a local directory
  3. Push the locally cloned repository to GitHub AE using the "mirror" option, which ensures that all references, such as branches and tags, are copied to the imported repository.
    $ cd REPO.git
    $ git push --mirror https://HOSTNAME/USER/REPO.git
    # Pushes the mirror to the new repository on GitHub AE
  4. Remove the temporary local repository.
    $ cd ..
    $ rm -rf REPO.git

If the repository you are importing contains large files, you may run into a warning or error. For more information on large files and how to manage them, see "About large files on GitHub."
