During December 2025, Arcwandx86 enhanced the YaLTeR/niri repository by updating its documentation to clarify support for multi-file configuration using the include directive. Collaborating with Ivan Molodetskikh, Arcwandx86 focused on technical writing and documentation in Markdown, ensuring that users managing complex deployments could more easily discover and implement multi-file configs. The update, anchored by a co-authored commit, addressed contributor feedback and improved onboarding by reducing setup time and increasing maintainability. While no bugs were fixed during this period, the work demonstrated depth in user guidance and technical communication, directly supporting the usability and scalability of configuration management in niri.
