Improve onboarding experience for first time contributors

Hi,
While exploring OWASP Nest from a first-time contributor perspective, I noticed that although the UI is clean and intuitive, it’s not very clear where new users should start or what their first step should be. This could make the onboarding experience slightly overwhelming for new contributors.
I’d like to propose adding a lightweight onboarding element, such as a “Start Here” button or guided entry points that help users quickly understand how to begin contributing. This would aim to improve discoverability and reduce friction for new contributors without affecting the existing design.

I’d be happy to work on this if it aligns with the project direction.
