Configuration

The tool creates a translation.config.json file during initialization:

{
  "name": "project-name",
  "sourceRepo": "https://github.com/QwenLM/qwen-code.git",
  "docsPath": "docs",
  "sourceLanguage": "en",
  "targetLanguages": ["zh", "de", "fr", "ru"],
  "outputDir": "content"
}

Environment Variables

Create a .env file with the following variables:

# Required: Qwen API key
OPENAI_API_KEY=your_qwen_api_key

# Optional: API configuration (defaults shown)
OPENAI_BASE_URL=https://api.qwen.ai/v1
QWEN_MODEL=qwen3-coder-plus
QWEN_MAX_TOKENS=4000

Alternative API Endpoints

You can also use other compatible endpoints:

# DashScope (Aliyun)
OPENAI_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1/
QWEN_MODEL=qwen-turbo

Requirements

• Node.js >= 18.0.0
• npm >= 8.0.0
• Qwen API key (or compatible OpenAI-format API)

Project Structure

After initialization, your project will have:

├── content/
│   ├── en/           # Source language documents (synced from repo)
│   ├── zh/           # Chinese translations
│   ├── de/           # German translations
│   ├── fr/           # French translations
│   └── ru/           # Russian translations
├── app/              # Next.js app directory (from template)
│   ├── [lang]/       # Dynamic language routing
│   └── layout.tsx    # App layout
├── .source-docs/     # Raw synced documentation
├── .temp-source-repo/# Temporary git clone (auto-managed)
├── translation.config.json
├── translation-changelog.json  # Translation history
├── last-sync.json    # Sync tracking
├── .env.example
├── next.config.mjs
└── package.json

How It Works

1. Sync: The tool clones/updates the source repository and detects changed files
2. Parse: Markdown documents are parsed while preserving structure and metadata
3. Translate: Content is segmented and translated using Qwen AI, with smart handling of code blocks and technical terms
4. Generate: Translated content is organized into a Nextra-based multilingual documentation site
5. Serve: The Next.js app serves the documentation with language switching
