🔹 Description:
To make it easier for contributors, we need clear documentation, including how to use our scripts, contribute new datasets, and understand the schema.

🔹 Expectations:

• Write a detailed README explaining the project's goals.
• Create contribution guidelines for new contributors.
• Provide code examples for using the dataset.
• Set up a template for GitHub Issues & Pull Requests.
• Organize documentation into sections (e.g., Data Sources, API Usage, Installation).
