Mario Harter focused on enhancing documentation for the modelica/fmi-ls-bus repository, delivering a comprehensive update to the README that catalogs two new tools, Vector SIL Kit FMU Importer and Vector vVIRTUALtarget. He used Markdown to clearly describe each tool’s functionality, provide direct links, and specify version availability, ensuring users can identify compatible releases. This documentation work improved onboarding and planning for FMI-LS bus integration by making tool discovery more transparent. While no bugs were fixed during this period, Mario’s contribution demonstrated depth in technical writing and documentation, emphasizing clarity and version control to reduce support overhead for future users.
