Worked on the ORNL/DataFed repository to deliver a comprehensive overhaul of installation and environment setup documentation. Focused on consolidating and clarifying user-facing guidance, the work removed redundant development environment instructions and reorganized both Docker and bare-metal installation steps for greater clarity. Updated the administrator installation documentation and ensured the changelog accurately reflected all improvements. Emphasized strong version control hygiene by maintaining clear commit history and traceability throughout the process. Utilized Markdown and reStructuredText to structure and present documentation, applying system administration expertise to streamline onboarding and reduce installation issues, ultimately improving maintainability for both users and administrators.
