You can now connect a template GitHub repository to CodeGrade. Enabling this feature will force your students to create a new GitHub repository from the template you have selected rather than selecting an existing repo. You can use this feature by enabling GitHub/GitLab as a submission method and then toggling the "Enable template repository" option. You will then be prompted to provide the URL of the template repo.
Note: You must make sure the GitHub repo you select as the template must be a template repository. This can be set in GitHub by going to settings and checking the box called "Template Repository" under the General Settings.
