Worked on the EnergySystemsModellingLab/MUSE_2.0 repository to enhance documentation clarity by standardizing glossary terminology, specifically focusing on the consistent use of 'Process/Technology' definitions. The approach centered on updating glossary.md to reduce ambiguity for both contributors and downstream users, supporting better onboarding and collaboration. No codebase changes were introduced, as the work was documentation-driven, leveraging skills in Markdown and technical writing. The update improved governance of terminology across the project’s models and documentation. This contribution demonstrated attention to detail and an understanding of the importance of clear, maintainable documentation in large-scale collaborative projects using Git and Markdown.
