Worked on the openwrt/luci repository to enhance documentation for luci-app-ddns, focusing on clarifying the configuration process for CA certificate validation. Updated guidance to specify that the CA certificates path should reference a certificate bundle file rather than a directory, aligning documentation and user interface with the actual validation logic. This change aimed to reduce user misconfigurations and support requests by providing more accurate setup instructions. Utilized JavaScript and JavaScript (PO) to ensure internationalization and documentation consistency. The work demonstrated attention to detail in documentation hygiene, contributing to a smoother onboarding experience for users configuring certificate-based validation in OpenWrt LUCI.
