Worked on enhancing the documentation experience for the LLNL/Surfactant repository by upgrading its Sphinx theme to Furo, focusing on both aesthetics and navigation. The project involved refining theme options to improve usability and integrating a copy code button, which streamlines the process of reusing code snippets directly from the documentation. Adjustments were made to documentation generation dependencies to ensure a smooth and reliable build process. The work was implemented using Python and Sphinx, with an emphasis on documentation best practices. This contribution addressed user experience in technical documentation, delivering a more accessible and efficient workflow for developers referencing project materials.
