Tasks:

Write an overview of CoSWID, explaining its purpose and features.
Provide setup instructions, including installation steps and dependencies.
Include usage examples to demonstrate how to use CoSWID.
Add any additional information that would be helpful for users (e.g., contribution guidelines, links to further documentation).
