What's missing in this repository!!

Code of Conduct
A Code of Conduct is crucial for maintaining a respectful and inclusive community. It sets clear expectations for behavior and outlines the steps for reporting and addressing unacceptable behavior. Here’s why it’s important:

Sets Behavioral Expectations: It clearly defines acceptable and unacceptable behavior, helping to create a welcoming and inclusive environment for all participants.
Promotes Respect and Inclusivity: It encourages respect and inclusivity, ensuring that everyone feels safe and valued within the community.
Conflict Resolution: It provides guidelines on how to handle conflicts and what actions will be taken in response to violations, promoting fairness and transparency.

Contributing File
The Contributing file provides guidelines for how to contribute to the project. This includes everything from coding standards and style guides to how to submit pull requests and report issues. Here’s why it’s essential:

Encourages Contributions: It provides clear instructions on how to get involved, making it easier for newcomers to start contributing.
Maintains Quality: It sets standards for contributions, ensuring that new code and documentation meet the project's quality requirements.
Streamlines the Process: It outlines the process for submitting contributions, reducing friction and confusion for contributors and maintainers alike.
