Great Docs

An easy-to-use documentation site generator for Python packages

PyPI Python versions Downloads MIT License CI


Great Docs turns your Python package into a polished documentation site in seconds. It auto-discovers your public API, detects your docstring format, generates structured reference pages, and renders a modern site: all from a single command. No templates to configure, no manual page authoring, no build system to learn.

A documentation site generated by Great Docs

Why Great Docs?

Writing documentation shouldn't be harder than writing the code it describes. Most documentation generators require you to author page templates, organize content by hand, and wire up a build system. Great Docs inverts that: point it at a Python package and it handles the rest.

  • Instant setup: great-docs init inspects your package and generates a complete config
  • Zero manual authoring: API reference pages are created automatically from your code
  • Real documentation, not stubs: renders full parameter tables, return types, examples, and cross-references from your existing docstrings
  • Looks great out of the box: gradient navbars, dark mode, responsive layout, GitHub widget, sidebar search
  • Deploys anywhere: one command creates a GitHub Actions workflow for GitHub Pages

Get Started in 60 Seconds

Install

pip install great-docs

Initialize, build, and preview

cd your-python-package

great-docs init     # auto-detect package, generate config
great-docs build    # generate and render the site
great-docs preview  # open in your browser at localhost:3000

That's it. Your documentation site is ready.

What Gets Generated

Every site built by Great Docs includes:

Landing Page

Your README is transformed into a landing page with a hero section, metadata sidebar (authors, license, links), and quick-start instructions.

API Reference

Classes, functions, methods, and attributes are automatically organized into categorized sections. Large classes get dedicated method pages. Every item links back to source code on GitHub.

A class documentation page with parameters and methods

A method documentation page with signature and examples

CLI Reference

Click-based CLIs are documented automatically with --help output rendered in terminal style, organized by command group.

Dark Mode

A persistent dark mode toggle with flash-free loading. Your users' preference is remembered across visits.

Configuration

All configuration lives in a single great-docs.yml file in your project root. The init command generates it for you, but you can customize everything:

# Theming
navbar_style: sky
content_style: lilac
dark_mode_toggle: true

# Branding
display_name: My Package
logo:
  light: assets/logo.svg
  dark: assets/logo-dark.svg

# Announcement banner
announcement:
  content: "v2.0 is here!"
  style: mint
  dismissable: true

# GitHub integration
repo: https://github.com/your-org/your-package # Optional override
github_style: widget

# CLI documentation
cli:
  enabled: true
  module: my_package.cli
  name: cli

# Multi-version documentation
versions:
  - tag: v2.0.0
    label: "2.0 (latest)"
  - tag: v1.5.0
    label: "1.5"

# Custom sections
sections:
  - title: Recipes
    dir: recipes
    navbar_after: User Guide

Custom HTML pages can live in a custom/ directory and are discovered automatically during build.

---
title: Landing Page
layout: passthrough
navbar: true
---
<section class="hero">...</section>

Use layout: passthrough to wrap the HTML body with the normal Great Docs shell, or layout: raw to copy the HTML file through unchanged. Set navbar: true to add the page to the site navbar using its title, or use navbar: {text: Showcase, after: Guide} for explicit navbar label and placement.

See the Configuration Guide for the full reference.
