DOC: Add Basic Snapshotting(git status, git commit) , branching and merging commands

[Devaki01]

The existing Readme.md file contains commands for cloning the projects to the users' local system. I would like to contribute by adding commands for branching, committing changes as well as push the changes in proper format.

Suggested Change
I would like to contribute by adding following commands:

Basic Snapshotting

-git status
-git add [file-name.txt]
-git commit -m "[commit message]"
-Branching and Merging

-git checkout -b [branch name]
-git push -u origin [branch name]
-git pull upstream main
-git remote -v
-git remote add upstream

Rationale
Contributors, especially the ones new to open source contributions will find it easier to contribute and thus it would play a role in ensuring easy workflow.
