In May 2025, Justin Kiggins updated the documentation for the chanzuckerberg/single-cell-explorer repository to clarify trademark policies and improve user guidance. He authored a new section in the README using Markdown, explicitly distinguishing CZ CELLXGENE trademarks and their ownership from the open-source software license. This documentation-focused contribution addressed potential confusion around branding and legal usage, reducing the risk of trademark misuse by repository users. By aligning the project’s documentation with branding and governance guidelines, Justin’s work enhanced legal clarity and streamlined support processes. The update demonstrated attention to detail in technical writing and a strong understanding of open-source compliance.
