Worked on the etalab-ia/OpenGateLLM repository to improve documentation stability and user experience. Focused on Markdown-based documentation hygiene by identifying and removing a broken Changelog link from the README, ensuring that only valid navigation options such as Documentation, Playground, API Status, and Swagger were presented to users. This targeted bug fix reduced potential confusion during onboarding and minimized unnecessary support queries. The work emphasized careful attention to documentation accuracy and navigation clarity, leveraging skills in Markdown and documentation best practices. No new features were introduced during this period, with efforts concentrated on maintaining code quality and repository usability.
