![version](https://img.shields.io/badge/version-3.0.15-blue) ![python](https://img.shields.io/badge/python-%3E%3D3.9-blue) ![docs](https://img.shields.io/badge/docs-auto--generated-blueviolet)

> Auto-generate and sync project documentation from source code analysis.

**code2docs** uses [code2llm](https://github.com/wronai/code2llm)'s `AnalysisResult` to produce human-readable documentation: README.md, API references, module docs, usage examples, and architecture diagrams.

```
code2llm  →  AnalysisResult  →  .toon / .mmd / context.md   (for LLM)
code2docs →  AnalysisResult  →  README.md / docs/ / examples/  (for humans)
```

## Installation

```bash
pip install code2docs
```

Or from source:

```bash
git clone https://github.com/wronai/code2docs
cd code2docs
pip install -e .
```

### Optional extras

```bash
pip install code2docs[watch]    # file watcher (watchdog)
pip install code2docs[mkdocs]   # MkDocs integration
pip install code2docs[dev]      # development tools
```

## Quick Start

```bash
# Generate full documentation for a project
code2docs ./my-project

# Generate only README
code2docs ./my-project --readme-only

# Sync (regenerate only changed modules)
code2docs sync ./my-project

# Watch mode (auto-resync on file changes)
code2docs watch ./my-project

# Initialize config file
code2docs init ./my-project

# Dry-run (show what would be generated)
code2docs ./my-project --dry-run
```

### Python API

```python
from code2docs import generate_readme, generate_docs, Code2DocsConfig

# Generate README
generate_readme("./my-project", output="README.md")

# Generate full docs with custom config
config = Code2DocsConfig(project_name="mylib", verbose=True)
docs = generate_docs("./my-project", config=config)
```

## Generated Output
