What problem does it solve? Building documentation sites with VitePress involves many moving parts—configuration, routing, theming, Markdown extensions, SSR constraints, and deployment—and this Skill provides structured guidance for each of these tasks. ## Core Features & Use Cases - Site Configuration & Routing: Set up defineConfig, file-based routing, clean URLs, rewrites, and base paths for sub-path deployments. - Markdown & Vue Authoring: Use custom containers, code groups, line highlighting, data loaders, dynamic routes, and Vue components directly in Markdown. - Theming & Deployment: Customize the default theme with CSS variables and slots, build custom themes, handle SSR compatibility, and deploy to GitHub Pages, Netlify, Vercel, or Nginx. - Use Case: You need to create a multi-language documentation site with a blog index generated from Markdown files and deploy it to GitHub Pages—this Skill walks through locales config, createContentLoader, and the GitHub Actions workflow. ## Quick Start Use the vitepress skill to help me configure a VitePress documentation site with a custom theme and deploy it to GitHub Pages.
