During August 2025, AImixAE developed a comprehensive Game Documentation and Onboarding Guide for the RBNR repository, focusing on improving the onboarding experience and clarifying contribution processes. By authoring a detailed README in Markdown, AImixAE provided a clear game overview, step-by-step run instructions, and actionable contribution guidelines. The work emphasized documentation best practices and version control hygiene, ensuring new contributors could join and participate with reduced cognitive load. While no bugs were addressed during this period, the depth of the documentation work enhanced community engagement and established a standardized approach to project documentation, supporting both users and future maintainers.
