During December 2024, Matthias Wählisch enhanced the qmk/RIOT repository by developing a new Collaboration section within the README.md, aimed at improving developer onboarding and clarifying the project's ecosystem relationships. He used Markdown to document RIOT’s partnerships with open-source projects such as Ariel OS, outlining collaboration practices and encouraging contributions from teams with aligned goals. This documentation initiative addressed onboarding friction and increased transparency for new contributors. While no major bugs were reported or fixed, Matthias maintained CI stability and repository health. His work demonstrated skills in documentation, stakeholder communication, and repository maintenance, providing foundational clarity for future cross-project collaboration.
