Reto Schneider updated the documentation for the home-assistant/developers.home-assistant repository to reflect a change in the default branch name from 'main' to 'dev'. This work focused on improving contributor onboarding by ensuring that all references in the Markdown-based documentation accurately guided users to target the correct branch for pull requests. Reto applied skills in collaboration, documentation, and version control to align contributor workflows with the repository’s evolving standards. While the scope was limited to a single feature over one month, the update addressed a common source of confusion, streamlining the contribution process and supporting more efficient collaboration within the project.
