[feat] Improve readme

[pushkaraj2007]

If you found any typo or any kind of mistake in the readme file of the repository, then feel free to raise an issue about it and improve it by creating a pull request.

Also if you want to add something new to the readme file, then do the same as I mentioned above.

Actually repo is not participating, but if I found that you have did a great contribution, I'll add the hacktoberfest-accepted label to your PR and that contribution will count towards hacktoberfest.

Happy coding :)
