VitePress is a Static Site Generator (SSG) built on Vite and Vue 3. It takes Markdown content, applies a theme, and generates static HTML that becomes an SPA for fast navigation. Perfect for documentation, blogs, and marketing sites.

Key Characteristics:

• File-based routing with .md files
• Vue components work directly in Markdown
• Fast HMR with instant updates (<100ms)
• Default theme optimized for documentation
• Built-in search (local or Algolia)

Before working with VitePress projects:

• Check .vitepress/config.ts for site configuration
• Look at .vitepress/theme/ for custom theme extensions
• The public/ directory contains static assets served as-is

The skill is based on VitePress 1.x, generated at 2026-01-28.
