Thanks @SachinRajakaruna for the PR.

I think some of the content in your PR can be repurposed to enhance CONTRIBUTING.md, but I don't think it makes sense to have two different contributing guidelines.

For example, info in the "💡 What You Can Contribute?" and "🧭 How to Get Started?" could be added.

We have an open issue to improve CONTRIBUTING.md #1; however, the information there likely exceeds the scope of this contribution.

For your reference, there is a similar repository with a CONTRIBUTING.md file that features an enhanced structure, which we can use as inspiration for this one.
