GitLab is a management platform for Git repositories that provides integrated features like continuous integration, issue tracking, team support, and wiki documentation. What is a Git Repository? The aim of Git is to manage software development projects and its files, as they are changing over time. Git stores this information in a data structure called a repository. Such a git repository contains a set of commit objects and a set of references to commit objects. A git repository is a central place where developers store, share, test and collaborate on web projects.
