Contributing

We welcome contributions! Submit changes in all three languages: English (en/, the source), Chinese (zh/), and Japanese (ja/). If you work with an AI agent (Claude Code, Cursor, etc.), it can produce the translations — point it at tools/translate/formatting-zh.md, tools/translate/formatting-ja.md, and writing-guides/glossary.md, the same rules our own agents follow.

Quick Start

1. Fork and clone the repository.
2. Create a branch, make your changes, and open a pull request against main.
3. Your PR will be reviewed by a maintainer, translations included — the docs team may adjust zh/ja wording during review.

Repository Structure

dify-docs/
├── en/              # English documentation (source language)
├── zh/              # Chinese translations (submitted with each change)
├── ja/              # Japanese translations (submitted with each change)
├── writing-guides/  # Style guide, formatting guide, glossary
├── .claude/skills/  # Claude Code documentation skills
├── tools/translate/ # Translation rules and utilities
├── docs.json        # Navigation structure

• English is the source: make the change in en/ first, then mirror it to zh/ and ja/ in the same PR. Keep the translation Note at the top of zh/ja pages.
• If you add or move a page, update all three language sections of docs.json.

File Format

Documentation files use MDX with required YAML frontmatter:

---
title: Your Page Title
description: A brief description of the page content.

Commit and PR Conventions

Commits and PR titles follow the same format: {type}: {description}

• Lowercase, imperative mood ("add", not "added" or "adds").
• No trailing period.
• Under 72 characters.

Type	When	Example
docs	New or updated content	docs: add workflow node configuration guide
fix	Typos, broken links, incorrect info	fix: correct broken link in knowledge base page
feat	Tooling or structural changes	feat: add search index to knowledge section
refactor	Reorganization without content changes	refactor: restructure knowledge base section
translate	Translation additions or updates	translate: update Japanese workflow pages
style	Formatting-only changes	style: fix heading levels in plugin guide
chore	Dependencies, config	chore: bump mintlify to 4.0.710

For non-obvious changes, add a body after a blank line explaining why:

fix: switch API response mode to streaming

Blocking mode was causing HTTP 504 timeouts on large pages.

Local Preview

npm i -g mintlify
mintlify dev

This starts a local development server at http://localhost:3000.

Setup

To enable the pre-commit hook (auto-regenerates the terminology database when you commit glossary changes):

git config core.hooksPath .githooks

Formatting Standards

We maintain a formatting guide in writing-guides/formatting-guide.md. If you use an AI-powered editor or assistant (Cursor, Claude Code, Copilot, etc.), you can point it to that file to check your work before submitting.

AI-Assisted Contributing

This repository includes Claude Code skills in .claude/skills/ that provide writing assistance for different documentation types. If you use Claude Code, these skills are available automatically after cloning.

Guidelines

• One topic per PR. Don't combine unrelated changes.
• All three languages. Every content change updates en/, zh/, and ja/ together; agent-produced translations are welcome when they follow the rules in tools/translate/.
• Update navigation. If you add a new page, add it to all three language sections of docs.json.
• Test locally. Run mintlify dev to verify your changes render correctly before opening a PR.
• No secrets. Never commit API keys, credentials, or .env files.
