Hello @rahuldkjain,
I think this project focuses on modularity and extensibility. Also, different people prefer different styles. It would be better to include both the projects with options to choose from since the configuration is just a matter of few words here and there.

P.S - I am the maintainer of the project suggested by @g-savitha. I was actually inspired by Athul 😄. He did a really nice job. But not to say, once you integrate it in the readme, mine would look more natural with all those colorful icons and GitHub's theme 😂.
