During October 2025, Ryan Meyer updated the mbta/api repository’s documentation to align with the current Phoenix framework workflow. He revised the README to replace the deprecated 'mix phoenix.server' command with 'mix phx.server', ensuring that new and existing developers could start the server correctly without confusion. This change, implemented using Markdown and a strong understanding of Phoenix and Elixir, addressed a common onboarding issue and reduced the likelihood of support requests related to outdated instructions. The work focused on documentation quality and change management, demonstrating attention to detail and a practical approach to maintaining accurate, developer-friendly project resources.
