@alextran1502 If you don't mind, Can I upgrade the Project by adding important file such as

CONTRIBUTING.md
A "Contributing.md" file is added to a repository to provide guidelines and
instructions for potential contributors on how to collaborate effectively with the project.
It typically includes information on coding standards, how to submit changes, reporting issues,
and other important details to streamline the contribution process and maintain a healthy
open-source community.
I pull the request kindly view it.

@Kalyanimhala thank you for the offer, it would make the most sense to have the internal team write the content of such file
