Adding a CodeOfConduct.md file to project

I suggest adding a Code of Conduct file to the project repository.

A Code of Conduct helps in:

1.Defining standards for how to engage in a respectful and inclusive way.
2.Setting clear expectations for behavior from all contributors.
3.Making the community more welcoming and professional.

Proposed Steps:

1.Add a CODE_OF_CONDUCT.md file in the root of the repository.
2.Use a standard template (e.g., [Contributor Covenant](https://www.contributor-covenant.org/)) or customize it as per the project's needs.
3.Link to this file from the README.md so contributors can easily find it.

This will help establish a healthy and collaborative environment as the project grows.

Please add label(eg. good first issue,etc) and assign this issue to me.
