During May 2025, Sluggy Fan contributed to the Shopify/ruby-lsp repository by improving contributor onboarding through targeted documentation updates. They revised the jekyll/contributing.markdown file, clarifying the correct VS Code workspace filename for sub-projects from 'lsp.code-workspace' to 'ruby-lsp.code-workspace'. This change addressed recurring setup confusion among new contributors and aligned documentation with the actual project structure. Sluggy Fan utilized Markdown to ensure the guidance was clear and accessible, focusing on documentation accuracy as their primary technical skill. The work was limited in scope but directly supported smoother onboarding and reduced errors for developers interacting with the repository’s sub-projects.
