Issue Description

What is this issue about?

This issue is about adding a CONTRIBUTING.md file to the repository. A CONTRIBUTING.md file serves as a guide for contributors to understand how they can contribute to the project, including the guidelines, best practices, and steps to follow.

Why is this issue important?

• A CONTRIBUTING.md file provides clear instructions for potential contributors, making it easier for them to participate in the project.
• It helps maintain consistency in the contribution process and ensures that contributions align with the project's goals.
• By including guidelines and best practices, it improves the overall quality of contributions.

What needs to be done?

• Create a CONTRIBUTING.md file in the root directory of the repository.
• Populate the file with guidelines, such as how to report issues, how to propose changes, and the coding style to follow.
• Include information on how to set up a development environment, run tests, and submit pull requests.
