A Git repository is a centralized location that stores a collection of files and their revision history. It is a distributed version control system that tracks changes in any set of computer files, usually used for coordinating work among programmers who are collaboratively developing source code during software development. A repository contains all of a projects files and each files revision history. When you create a repository, you can choose to make the repository public or private, and you can give other people collaborator access so that they can collaborate on your project. If a repository is owned by an organization, you can give organization members access permissions to collaborate on your repository.
A Git repository is the .git/ folder inside a project, and this repository tracks all changes made to files in the project, building a history over time. This means that if you delete the .git/ folder, you delete your projects history. GitKraken, a Git GUI client, allows you to create and clone Git repositories, and you can also work with repositories on GitLab, Bitbucket, and Azure DevOps.
