If you want to import from a GitHub Enterprise instance, you need to use GitLab Enterprise; please see the [EE docs for the GitHub integration](http://doc.gitlab.com/ee/integration/github.html).
* Click on the "Import project from GitHub" link and you will be redirected to GitHub for permission to access your projects. After accepting, you'll be automatically redirected to the importer.
* To import a project, you can simple click "Add". The importer will import your repository, issues, and pull requests. Once the importer is done, a new GitLab project will be created with your imported data.
When you import your projects from GitHub, it is not possible to keep your labels, milestones, and cross-repository pull requests. We are working on improving this in the near future.
