Worked on documentation alignment for the cfug/dart.cn repository, focusing on maintaining accuracy in package management service listings. Addressed a documentation bug by removing JetBrains Space from the list of custom package repository services, reflecting its pivot to SpaceCode and the absence of package management functionality. This update, implemented using Markdown and documentation best practices, aimed to prevent user confusion and reduce support overhead. The change was managed through a targeted commit, demonstrating disciplined change control and clear traceability. The work emphasized attention to detail in technical writing and ensured that the documentation remained current and reliable for end users.
