During June 2025, Li Tian worked on the LianjiaTech/bella-openai4j repository, focusing on enhancing project documentation and branding. He added a 'Powered by DartNode' badge to the README.md file using Markdown, which provides clear attribution and a direct link to the DartNode website. This update, while modest in code size, improved the project's discoverability and credibility for new users. Li Tian’s disciplined approach to documentation emphasized source-control hygiene and maintainability. Although no bugs were addressed during this period, his work demonstrated attention to detail in documentation practices, laying groundwork for future collaboration and marketing opportunities within the project.
