3. What is Git?
Git is a Version Control System (VCS) designed to make it
easier to have multiple versions of a code base,
sometimes across multiple developers or teams.
It allows you to see changes you make to your code and
easily revert them.
It is NOT GITHUB!
4. Ok, then what is Github?
github.com is a website that hosts git repositories on a
Hosting repositories on Github facilitates the sharing of
codebases among teams by providing a GUI to easily fork
or clone repos to a local machine.
By pushing your repositories to Github, you will pretty
much automatically create your own developer portfolio
5. You can interact with Git using the Graphical User Interface (GUI)
provided by GitHub, or through the Command Line Interface (CLI).

makes our local changes visible in remote repository

17. git with VS Code
Untracked File Status (U):
Files not yet added to repository.
VS Code displays a U beside the filename.
Unmodified File Status:
Tracked files that have not been changed.
Modified File Status (M):
Tracked files that have been changed.
VS Code displays an M beside the filename
Ignore File Status:
Files that match a pattern or exact match in .gitignore
VS Code grays out the filename.
Staged File Status (A):
