Worked on enhancing the documentation and onboarding experience for the UCL-CCS/EasyVVUQ repository, focusing on improving accessibility and reliability for new users. Upgraded the documentation theme to sphinx-rtd-theme using Sphinx and reStructuredText, which improved readability on Read the Docs. Addressed build stability by introducing a docs/requirements.txt file to pin dependencies, ensuring consistent documentation builds. Improved the onboarding process by linking installation instructions, conceptual overviews, and a MyBinder tutorial directly within the documentation. Fixed issues in .rst files to resolve rendering and build errors, resulting in more accurate and accessible documentation for both contributors and end users.
