GIT:

Git is a distributed version control system used for tracking changes in source code during software development. It enabling multiple developers to work together on non-linear development.
We will work with Github. It is a web-based platform that hosts and manages Git repositories. It extends the capabilities of Git, making collaboration, code sharing, and project management more efficient.
I will not describe the complete documentation here, I am going to clone a github repository for this article. So I will talk about Git Repository and Clone.

GIT Repository:

In Git, a repository (or repo) is like a project’s folder that contains all the files and the version history. There are 2 Types of Repo. A) Private Repo, B) Public Repo. Here is our public “first-docker-application” Repo.

“git clone” CLI command is primarily used to point to an existing REPO and make a clone or copy of that at in a local machine in new directory in your machine or server .
