Worked on improving the documentation for the eSIM workflow in the GL-iNet/docs4.x repository, focusing on enhancing user-facing reliability and onboarding. Addressed a bug by updating the firmware download path in the eSIM setup guide, ensuring that users are directed to the standardized firmware directory for accurate firmware updates. This change, implemented in Markdown, aimed to reduce user friction and potential support queries by providing clear and reliable instructions. The documentation update was validated against repository standards and prepared for release notes, demonstrating attention to detail and a methodical approach to maintaining high-quality technical documentation using Markdown and documentation best practices.
