@seokho-son FYI we’re organizing zh-tw localization execution and following the Arabic/Farsi initiation tracking format. We’re also recruiting contributors; any pointers to the right process or contacts would be appreciated.

Start with the localization guide linked in the issue and review the outstanding checklist items, especially the zh-tw development branch. Read hugo.toml, content/zh-tw/, and i18n/zh-tw/zh-tw.toml, then inspect the linked setup, tutorials, and home or release work. Done requires completing the minimum required content and README, validating the build and preview, and merging the development branch.
