Marie Roald enhanced the pyOpenSci/python-package-guide repository by delivering targeted improvements to its Poetry packaging documentation. She focused on clarifying dependency management, versioning standards, and highlighting potential pitfalls associated with Poetry’s default settings. Using Markdown and her expertise in documentation and Python packaging, Marie incorporated reviewer feedback to improve clarity, corrected table formatting, and ensured the accuracy of packaging standards. Her work addressed common sources of user confusion and reduced onboarding time for new contributors. While the scope was limited to a single feature over one month, the updates provided practical guidance for users packaging Python projects with Poetry.
