Amir Golparvar enhanced the FAIRmat-NFDI/nomad-docs repository by updating the HDF5Normalizer documentation to provide a comprehensive and precise list of supported HDF5 file extensions. Using Markdown and a focus on clear technical writing, Amir aligned the documentation with the current codebase, clarifying which file types the normalizer can process. This targeted update addressed user confusion and improved onboarding by making the tool’s capabilities more transparent. Although the work did not involve bug fixes or code changes, it demonstrated attention to maintainability and user experience, ensuring that future updates to the documentation remain consistent with the underlying implementation.
