During November 2025, Rüdiger Kennke focused on improving the onboarding experience for the DataDog/java-profiler repository by enhancing its documentation. He identified and fixed a bug in the macOS setup guide, correcting the Homebrew clang-format package name to prevent installation errors and reduce user confusion. Working primarily with Markdown, Rüdiger applied his documentation skills to ensure the setup instructions were accurate and easy to follow, which helped streamline the onboarding process for new contributors. His work emphasized documentation hygiene, with clear commit messages and traceable pull requests, contributing to the maintainability and auditability of the project’s technical documentation.
