What problem does it solve? Building a documentation site from scratch requires wiring together MDX rendering, search, i18n, AI chat, feedback collection, and deployment configuration. This Skill provides expert guidance for Geistdocs, Vercel's documentation template, so you can set up and customize a full-featured docs site without assembling each piece manually. ## Core Features & Use Cases - Project scaffolding and configuration: Initialize a project with npx @vercel/geistdocs init and customize branding, navigation, AI prompts, GitHub integration, and translations via the root geistdocs.tsx config file. - MDX authoring guidance: Write documentation pages with frontmatter, code blocks with highlighting and diff annotations, Mermaid diagrams, and GFM tables, with automatic file-based routing from content/docs/. - Built-in docs infrastructure: Set up AI chat (Ask AI), i18n with auto-translation, feedback widgets that create GitHub Issues, RSS feeds, llms.txt endpoints, and Vercel deployment. - Use Case: You need to launch documentation for a new product. Use this Skill to scaffold a Geistdocs project, configure your logo and nav, write MDX pages with syntax-highlighted code examples, enable the AI assistant, and deploy to Vercel. ## Quick Start Ask the assistant to scaffold a new Geistdocs documentation project and walk you through configuring the geistdocs.tsx file for your product.
