# Building Documentation

## Build Commands

### English (Default)

```bash
make.bat html          # Windows
make html              # Linux/macOS
```

Output: `build/html/`

### Chinese Simplified

```bash
make.bat html-zh_CN    # Windows
make html-zh_CN        # Linux/macOS
```

Output: `build/html/zh_CN/`

### Japanese

```bash
make.bat html-ja       # Windows
make html html-ja      # Linux/macOS
```

Output: `build/html/ja/`

### Build All Languages

```bash
make.bat all           # Windows
make all               # Linux/macOS
```

This creates `build/html/en/`, `build/html/zh_CN/`, and `build/html/ja/`.

## Clean Build Artifacts

```bash
make.bat clean         # Windows
make clean             # Linux/macOS
```

This removes the entire `build/` directory.

## Advanced: Clean and Rebuild

```bash
make.bat clean && make.bat html     # Windows
make clean && make html             # Linux/macOS
```

## Build Environment Variables

The build system uses the `BUILD_LANGUAGE` environment variable:

```bash
# Explicit language specification
BUILD_LANGUAGE=zh_CN sphinx-build -b html source build/html/zh_CN
```

## Build Output

After successful build, check:

- **English**: `build/html/index.html`
- **Chinese**: `build/html/zh_CN/index.html`
- **Japanese**: `build/html/ja/index.html`

Each build is completely independent and doesn't include other language files.
