Developed a comprehensive Development Tools Guide for the beyond-all-reason/spring repository, focusing on improving onboarding and standardizing tooling documentation for game development on Recoil. The work involved authoring a centralized resource in Markdown, curating and organizing links to external modeling, animation, and mapmaking tools. Emphasizing clarity and reusability, the guide established a template for future documentation efforts and aligned with repository standards. No bug fixes were addressed during this period, as the primary focus remained on documentation. This contribution leveraged skills in technical writing and documentation, supporting faster tool adoption and providing a foundation for consistent developer guidance across teams.
