Tycho Hofstra updated the editorial roster in the ubvu/open-handbook repository, ensuring the handbook accurately reflected the current editorial team by adding Tycho Hofstra and Peter Vos to the editors-guide.qmd file. Using Markdown and Quarto (QMD) for documentation, Tycho maintained repository health and kept governance documents up to date, which reduced onboarding friction and improved the accuracy of team information for readers. The work involved Git-based workflows and careful documentation maintenance, with no reported regressions or bugs. This update provided business value by ensuring the handbook remained a reliable source of truth for editorial staff and new contributors.
