Worked on the major/traefik repository with a focus on improving documentation accuracy for Swarm CLI configuration. Addressed a documentation bug by correcting the provider prefix in the endpoint configuration example, updating it from 'docker' to 'swarm' to match the actual CLI argument required for Swarm mode. This change, implemented using Markdown and documentation best practices, reduced the risk of user misconfiguration and helped align the documentation with real-world usage. The work emphasized maintaining consistency with repository guidelines, supporting smoother onboarding for new users, and minimizing support requests. No new features were added during this period, with efforts centered on documentation quality.
