Create an organization for your group https://help.github.com/articles/creating-a-new-organization-from-scratch/ and then in https://github.com/Chalmers-Control-Automation-Mechatronics/AutonomousTwizy click the Fork button top-right on your screen. Fork into the organization you created.
You will now have your own version of this repository and you can invite your group members to your organization in order to collaborate with the group. Since you have your own repository, you won't see changes other groups make automatically. This is intended in order to reduce code conflicts between the group.
When you have done changes that are working and you want to share them with the rest of the Twizy team, you can create a Pull Request. To do that, go into your organizations repository, and click the Pull Requests tab, then click New pull request. Make sure base fork is set as Chalmers-Control-Automation-Mechatronics/AutonomousTwizy and base is master. Also make sure head fork is set as your repository. Here you can now review your changes and create a nice title and description of what you have done. A maintainer can now review this and accept the pull request, which will merge your changes into the main repository.
