Worked on enhancing developer documentation within the espressif/esp-dev-kits repository, focusing on the ESP32-S2-DevKitC-1 and ESP32-S2-DevKitM-1 boards. Delivered targeted updates by replacing outdated visuals and improving formatting in the Chinese user guide using reStructuredText and rst, which clarified hardware references and streamlined onboarding. Later, migrated documentation to reflect the end-of-life status of ESP32-S2-DevKitM-1, providing clear transition guidance to ESP32-S2-DevKitC-1-N8R2. Emphasized technical writing and localization, ensuring documentation aligned with product lifecycle changes. The work prioritized accuracy, consistency, and developer support, resulting in two feature updates over two months without direct bug fixes.
