What is GitHub?
GitHub is a code hosting service, GitHub is a place where developers store their projects and they work together.
GitHub is a living, ever-changing, searchable record that tells the story of how and why our code is the way it is. The ability to document code effectively using Git (or another version control system) is just as important as being able to ship a feature, write clean code or readable tests.
First you have to download and install Git on your system, after that create a directory/folder in your system. Write the git init command so it will contain the complete history of changes made to that directory.
Note: .git/ folder is always in hidden folder.
