Contributed to the CleverRaven/Cataclysm-DDA repository by enhancing the project’s documentation, specifically updating the JSON_INFO.md file to clarify the mapping between terrain types and floor types within the game data. Focused on improving data quality, the work involved detailed Markdown editing to explicitly document how terrain representations correspond to floor data, reducing ambiguity for downstream parsers and modding tools. This documentation update addressed a longstanding source of confusion, enabling more reliable world-generation and mod development. The contribution demonstrated attention to detail in technical writing and a strong understanding of data structures, with an emphasis on maintainability and clarity for future contributors.
