Worked on improving the documentation for the FAIRmat-NFDI/nomad-docs repository by addressing a broken link in the HDF5 customization section. The update involved correcting the Markdown path to the H5WebAnnotation class reference, ensuring that users are directed to the appropriate documentation resource. This change enhanced the reliability of the onboarding process and reduced potential confusion for new users. The work focused on documentation quality, utilizing Markdown for precise link management and verification. By resolving this issue through a targeted commit, the developer contributed to a smoother user experience and minimized the likelihood of support requests related to documentation navigation.
