During December 2025, Nietaki enhanced the qmk/qmk_firmware repository by focusing on documentation improvements that clarified the use of custom keycodes in the info.json file and provided updated guidance on matrix masking. Employing technical writing and documentation skills, Nietaki used Markdown to deliver clearer usage patterns and reduce ambiguity for both users and contributors. The work involved close collaboration with firmware maintainers to align terminology and examples across the documentation, resulting in easier onboarding for new contributors and fewer support queries. Although no bugs were fixed, the depth of the documentation changes contributed to a more maintainable and accessible codebase.
