Add simple contribution guidelines / minor documentation improvement

[Yuvi242424]

Hi maintainers 👋

I recently forked this repository and I am exploring it as part of my learning.
I noticed that first-time contributors may benefit from a very small clarification
in the documentation.

I would like to contribute a minor documentation improvement (README or comments),
such as clarifying how to get started or adding a small note for beginners.

Please let me know if this contribution would be acceptable.
Thank you!
