LLM-Friendly Documentation Export

Zudoku can generate LLM-friendly versions of your documentation following the llms.txt specification.

During build, you can optionally generate:

• .md files - Individual pages with frontmatter removed (via publishMarkdown)
• llms.txt - Summary with links to all pages
• llms-full.txt - Complete documentation in one file

Per-page .md export is enabled by default. The two aggregate llms.txt files are opt-in.

Configuration

LLM features are configured through the docs section in your config:

Code
export default {
  docs: {
    files: "pages/**/*.{md,mdx}", // Your markdown files
    publishMarkdown: true, // Generate .md files
    llms: {
      llmsTxt: true, // Generate llms.txt
      llmsTxtFull: true, // Generate llms-full.txt
      includeProtected: false, // Exclude protected routes
      title: "Acme API",
      description: "Build and operate integrations with the Acme API.",
      instructions:
        "Use these docs when creating or debugging an Acme integration. Start with the quickstart, then consult the API reference for request and response schemas.",
    },
  },
};

llmsTxt

Type: boolean Default: false

Generates an llms.txt file with links to all documentation pages:

Code
# Acme API

> Build and operate integrations with the Acme API.

Use these docs when creating or debugging an Acme integration. Start with the quickstart, then
consult the API reference for request and response schemas.

## Documentation

- [Quickstart](/docs/quickstart.md): Get started with Zudoku
- [Writing](/docs/writing.md): A guide to writing documentation

title

Type: string Default: the configured site title, or "Documentation"

Sets the project or site name in the required H1 at the top of llms.txt. It also sets the H1 in llms-full.txt when that file is enabled.

description

Type: string Default: "Documentation files for Large Language Models"

Sets the short summary in the blockquote immediately after the H1.

instructions

Type: string Default: undefined

Adds optional guidance between the blockquote and the documentation link section. Use it to tell agents which concrete jobs the documentation is best suited for and how to navigate or call the product. The value can contain Markdown paragraphs and lists, but should not contain headings; headings in llms.txt are reserved for sections containing link lists.

llmsTxtFull

Type: boolean Default: false

Generates llms-full.txt containing the complete content of all pages.

includeProtected

Type: boolean Default: false

By default, protected routes are excluded. Set to true to include them in the generated files.

Output

Generated files are available in the output directory after build:

Code
dist/
├── llms.txt           # Generated if llmsTxt: true
├── llms-full.txt      # Generated if llmsTxtFull: true
└── docs/
    ├── quickstart.md  # Generated if publishMarkdown: true
    ├── writing.md
    └── ...

On Vercel builds, this tree is written beneath .vercel/output/static/ instead of dist/. The deployed public URLs remain the same. See the Vercel deployment guide for the generated routing and Markdown content-negotiation behavior.

Important: Individual .md files are only kept in the final build if publishMarkdown: true. If only llmsTxt or llmsTxtFull is enabled, the .md files are generated temporarily during the build but deleted after the llms.txt files are created.

Redirect pages, error pages (400, 404, 500), and protected routes (unless includeProtected: true) are automatically excluded from all generated files.
