# documentation

Open standard for guiding AI coding agents at the repository level

AGENTS.md is an open standard format adopted by 60,000+ open-source projects for providing AI coding agents with repository-level instructions. With 20,000+ GitHub stars, it has been adopted by GitHub Copilot, OpenAI Codex, Google Gemini CLI, and multiple IDEs as the de facto way to communicate project context and coding conventions to AI agents.

Twelve-lesson curriculum for building AI coding agents from scratch

Learn Claude Code is a comprehensive educational framework with 12 structured lessons teaching AI coding agent construction from first principles. With over 46,000 GitHub stars and 7,000 forks, it provides complete runnable Python implementations progressing from a 50-line bash agent to a 550-line skills agent with modular extensibility and subagent orchestration.

AI-powered marketing-ready READMEs from code

PitchDocs is an AI documentation generator that scans codebases to produce marketing-ready READMEs, changelogs, and AI context files like llms.txt. It bridges the gap between raw source code and consumer-ready technical communication, targeting the growing need for high-quality README files that serve both human developers and AI agents accessing documentation.

AI documentation generator from code repositories

DocuWriter.ai creates technical documentation from code repositories by scanning files, understanding patterns, and generating structured documentation including API references, function descriptions, and architectural overviews. It supports batch processing for entire repositories, serving as a zero-to-one documentation tool for undocumented codebases that need initial documentation coverage quickly.

Up-to-date docs for AI code editors via MCP

Context7 is an MCP server developed by Upstash that injects up-to-date, version-specific documentation directly into AI code editors and coding assistants. By typing 'use context7' in prompts, developers get accurate library documentation instead of hallucinated or outdated API references. It pulls from official source documentation and serves it through the Model Context Protocol, solving the common problem of LLMs generating code with incorrect or nonexistent API calls.

Curated collection of agent skills and capabilities

An opinionated project scaffolding tool that generates AI-ready codebases with pre-configured CLAUDE.md files, git hooks, and CI/CD templates. Ensures new projects follow best practices for AI-assisted development from day one, including structured prompts, context files, and workflow configurations that help AI coding agents understand and navigate the codebase effectively.

Toolkit for spec-driven development with AI

GitHub's official toolkit for spec-driven development. Write specifications in natural language and let AI coding agents implement them with structure, consistency, and traceability. Bridges the gap between product requirements and AI-generated code by providing a standardized format that agents can follow reliably across complex projects.

Markdown with JSX components

MDX is a format that seamlessly combines Markdown with JSX, allowing authors to embed React components directly inside Markdown documents. It solves the problem of static content being too limited for modern web applications by making documentation interactive — charts, custom widgets, and live code examples can live alongside prose. MDX is the backbone of Docusaurus, Nextra, and countless React-based docs stacks.

Beautiful docs for Next.js App Router

Fumadocs is a documentation framework built specifically for Next.js that provides a complete set of tools for creating high-performance documentation sites within the Next.js App Router. Offers tight integration with server components, middleware, and API routes, plus headless UI primitives, MDX processing, built-in search, and flexible theming — giving teams full control over their docs' look and feel.

Next.js documentation framework

Nextra is a Next.js-based static site generator designed for documentation websites and blogs with minimal configuration. Leverages the full Next.js ecosystem with pre-built themes (Docs and Blog), MDX support, automatic file-system routing, full-text search, dark mode, and i18n. Developers get fast, SEO-friendly docs sites while keeping access to Next.js features like React Server Components.

Project documentation with Markdown

Python-based static site generator purpose-built for project documentation. Simple YAML configuration, fast build times, and a rich plugin ecosystem. The Material for MkDocs theme adds a polished look with search, dark mode, and advanced navigation features. The go-to documentation tool for open-source projects and internal engineering docs that need to look professional with minimal effort.

OpenAPI-powered developer portals

OpenAPI documentation renderer with a clean three-panel layout that generates beautiful, responsive API reference pages from your OpenAPI spec. Available as open-source React component or CLI-generated static site. Supports code samples in multiple languages, search, and deep linking, making it the go-to choice for teams who want polished API docs without custom development.

Documentation generator for TypeScript

Documentation generator that converts TypeScript source comments into HTML, JSON, or Markdown reference sites. TypeDoc reads JSDoc-style annotations directly from .ts files, using the TypeScript compiler API to extract types, signatures, classes, and modules without duplicating annotations. Themes and plugins customize output for libraries, monorepos, and design systems. De facto standard for documenting open-source TypeScript packages — used by Pixi.js, NestJS, and thousands more.

API design and documentation standard

Industry-standard specification for defining RESTful APIs with a comprehensive ecosystem of tools. OpenAPI Specification (formerly Swagger) describes endpoints, parameters, responses, and authentication in YAML/JSON format. Swagger UI generates interactive API documentation, Swagger Editor provides a visual spec editor, and Swagger Codegen generates server stubs and client SDKs in 40+ languages. The foundation of API-first development workflows used by millions of developers worldwide.

Beautiful, personalized API docs

Developer hub platform for creating interactive API documentation with try-it-now API explorer, auto-generated references from OpenAPI specs, custom landing pages, changelog, guides, and usage analytics. Features personalized docs that show API keys and example responses based on the logged-in user. Tracks which endpoints developers actually use. Integrates with GitHub for syncing docs from repos. Used by companies like Twilio and Shopify for their developer portals.

Build stellar documentation with Astro

Starlight is an open-source Astro-based documentation theme from the Astro team that produces fast, accessible, SEO-friendly docs sites with minimal config. Ships dark mode, full-text search via Pagefind, versioned navigation, i18n, auto-generated sidebars, and beautiful defaults out of the box. Ideal for open-source projects, product docs, and technical handbooks that want first-class performance.

Vite & Vue powered static site generator

Static site generator built on Vite and Vue.js for fast documentation sites. Write in Markdown with embedded Vue components. Automatic sidebar from file structure, full-text search, dark mode, i18n, code group tabs, and customizable themes with Tailwind CSS. Minimal JavaScript for near-instant page loads. Created by Evan You (Vue/Vite creator). Powers Vue, Vite, and Pinia docs. The standard docs tool for Vue ecosystem projects.
