Worked on the PolyhedraZK/Expander repository to enhance project transparency and contributor experience by focusing on documentation improvements. Introduced GitHub Actions build status and license badges to the Markdown-based README, providing clear visibility into project health and licensing for users and contributors. Updated onboarding and contribution guidelines to streamline the workflow for new contributors, emphasizing documentation hygiene and maintainability. The work centered on using Markdown for documentation and integrating CI signals, laying the foundation for future automation and quality assurance enhancements. No bugs were addressed during this period, as the primary focus remained on documentation quality and process clarity.
