Hi! @omsuneri
I’d like to work on this issue,
My plan is to update the CONTRIBUTING.md by:

• Adding a new section describing guidelines for using AI/LLM tools during development (responsibility, review, testing, style consistency, etc.)
• Expanding the pull request workflow with clearer steps for creating branches, linking issues, and submitting PRs.

The goal is to keep the additions consistent with the existing documentation style and avoid changing current workflows just clarifying best practices.
I will open a PR soon. Feedback or preferences before I start are welcome.
