Cheerawab contributed to the MCDReforged/PluginCatalogue repository by implementing Traditional Chinese localization for project documentation. Focusing on accessibility and internationalization, Cheerawab translated the CONTRIBUTING and README files into zh_tw and updated documentation links to reference these new translations. This work, carried out in Markdown, aimed to improve onboarding and usability for ZhTW-speaking contributors and users. The approach centered on expanding documentation discoverability and aligning with the project's localization strategy. While the contribution was limited to a single feature over one month, it addressed a clear need for multilingual support and demonstrated attention to detail in documentation and internationalization practices.
