Worked on refining the documentation for the dotnet/core repository to accurately represent Ubuntu 24.04 support, focusing on clarifying which architectures are officially supported. Addressed a documentation bug by updating the supported OS matrix, ensuring only Arm64 and x64 architectures were listed for Ubuntu 24.04 and removing references to unsupported platforms. This targeted change, implemented in Markdown, aimed to reduce user confusion and lower the risk of misconfiguration for contributors and users. The work demonstrated attention to detail in documentation practices and contributed to smoother onboarding experiences by aligning technical guidance with actual platform compatibility requirements. No new features were developed.
