Worked on enhancing the Sicilian language documentation within the UniversalDependencies/docs repository, focusing on improving clarity, consistency, and maintainability. Consolidated and updated the main index file to better organize information on Sicilian morphology, linguistic tags, and usage, while removing outdated instructional content. Standardized file naming conventions by renaming template-index.md to index.md, streamlining contributor onboarding and documentation hygiene. Added detailed examples, particularly clarifying the use of the auxiliary verb 'avíri' in compound tenses. All work was completed using Markdown, leveraging skills in documentation and linguistics to deliver a more accessible and searchable resource for future contributors and users.
