sudo apt install git

The first thing you’ll want to do with GitLab is create a new project. This is accomplished by clicking the “+” icon on the toolbar. You’ll be asked for the project’s name, which namespace it should belong to, and what its visibility level should be. Most of what you specify here isn’t permanent, and can be re-adjusted later through the settings interface. Click “Create Project”, and you’re done. <a href="https://git-scm.com/book/be/v2/Git-on-the-Server-GitLab" target="_blank">More..</a>
