Worked on improving documentation quality in the actions/itgmania212121 repository by updating the README.md file to direct users to the specific ITGmania API documentation page for Lua-for-ITGmania. This change, implemented using Markdown, enhanced the accuracy and clarity of the documentation, reducing ambiguity for developers seeking Lua integration resources. The update involved verifying the validity of the new link and ensuring alignment with current ITGmania API resources, which supports faster onboarding and better user guidance. Demonstrated attention to documentation hygiene and version control practices, focusing on clear commit messaging and maintaining up-to-date references for the developer community.
