@AasthaGitHub ma'am and @akrishna0 sir I request you to please review my work

[AasthaMehtaTech]

Hello @Sejal1Verma, greetings for your first contribution here.
Contributing guidelines would be more beginner friendly when we include the exact commands which one needs to follow. So, kindly make the following changes:

• Describe exact steps (with commands - for different systems: Windows, Mac, Linux)
• It'd be great if u could attach actual pictures of example how you made this PR.
• In PR description remove the unnecessary details & point a reference to the prevailing documentation issue.
• U might want to add the rules of maintaining the decorum/coding style while one wants to contribute.

Please follow the template don't just make a pull request after making changes describe everything as asked in the PR template if possible
