# mdBook Setup for VAPORA Documentation

## Overview

VAPORA documentation is now fully integrated with **mdBook**, a command-line tool for building beautiful books from markdown files. This setup allows automatic generation of a professional-looking website from your existing markdown documentation.

## ✅ What's Been Created

### 1. **Configuration** (`docs/book.toml`)
- mdBook settings (title, source directory, output directory)
- HTML output configuration with custom branding
- GitHub integration for edit links
- Search and print functionality enabled

### 2. **Source Structure** (`docs/src/`)
- **SUMMARY.md** — Table of contents (85+ entries organized by section)
- **intro.md** — Landing page with platform overview and learning paths
- **README.md** — Documentation about the mdBook setup

### 3. **Custom Theme** (`docs/theme/`)
- **vapora-custom.css** — Professional styling with VAPORA branding
  - Blue/violet color scheme matching VAPORA brand
  - Responsive design (mobile-friendly)
  - Dark mode support
  - Custom syntax highlighting
  - Print-friendly styles

### 4. **Build Artifacts** (`docs/book/`)
- Static HTML site (7.4 MB)
- Fully generated and ready for deployment
- Git-ignored (not committed to repository)

### 5. **Git Configuration** (`docs/.gitignore`)
- Excludes build output and temporary files
- Keeps repository clean

```

## 🚀 Quick Start

### Install mdBook (if not already installed)

```bash
cargo install mdbook
```

### Build the documentation

```bash
cd docs
mdbook build
```

Output will be in `docs/book/` directory (7.4 MB).

### Serve locally for development

```bash
cd docs
mdbook serve
```

Then open `http://localhost:3000` in your browser.

Changes to markdown files will automatically rebuild the documentation.

### Clean build output

```bash
cd docs
mdbook clean
```

## 📝 Content Guidelines

### File Naming
- Root markdown: **UPPERCASE** (README.md)
- Content markdown: **lowercase** (setup-guide.md)
- Multi-word: **kebab-case** (setup-guide.md)

### Markdown Standards
1. **Code Blocks**: Language specified (bash, rust, toml)
2. **Lists**: Blank line before and after
3. **Headings**: Proper hierarchy (h2 → h3 → h4)
4. **Links**: Relative paths only (`../section/file.md`)

### Internal Links Pattern

```markdown
# Correct (relative paths)
- [Setup Guide](../setup/setup-guide.md)
- [ADR 0001](../adrs/0001-cargo-workspace.md)

# Incorrect (absolute or wrong format)
- [Setup Guide](/docs/setup/setup-guide.md)
- [ADR 0001](setup-guide.md)
```

## 🔧 Maintenance

### Adding New Documentation

1. Create markdown file in appropriate subdirectory
2. Add entry to `docs/src/SUMMARY.md` in correct section
3. Use relative path: `../section/filename.md`
4. Run `mdbook build` to generate updated site

Example:
```markdown
# In docs/src/SUMMARY.md
## Tutorials
- [My New Tutorial](../tutorials/my-tutorial.md)
```

### Updating Existing Documentation

1. Edit markdown file directly
2. mdBook automatically picks up changes
3. Run `mdbook serve` to preview locally
4. Run `mdbook build` to generate static site

### Fixing Broken Links

mdBook will fail to build if referenced files don't exist. Check error output:

```
Error: Cannot find file '../nonexistent/file.md'
```

Verify the file exists and update the link path.

## 📦 Deployment

### Local Preview
```bash
mdbook serve
# Open http://localhost:3000
```

### GitHub Pages
```bash
mdbook build
git add docs/book/
git commit -m "docs: update mdBook"
git push origin main
```

Configure repository:
- Settings → Pages
- Source: `main` branch
- Path: `docs/book/`
- Custom domain: `docs.vapora.io` (optional)

### Docker (CI/CD)
```dockerfile
FROM rust:latest
RUN cargo install mdbook

WORKDIR /docs
COPY . .
RUN mdbook build

# Output: /docs/book/
```

### GitHub Actions
Add workflow file `.github/workflows/docs.yml`:

```yaml
name: Documentation Build

on:
  push:
    paths: ['docs/**']
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: peaceiris/actions-mdbook@v4
      - run: mdbook build
      - uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./docs/book
```

## 🐛 Troubleshooting

| Problem | Solution |
|---------|----------|
| **Broken links in built site** | Use relative paths: `../file.md` not `/file.md` |
| **Search not working** | Rebuild with `mdbook build` |
| **Build fails silently** | Run `mdbook build` with `-v` flag for verbose output |
| **Theme not applying** | Remove `docs/book/` and rebuild |
| **Port 3000 in use** | Change port: `mdbook serve --port 3001` |
| **Missing file error** | Check file exists and update SUMMARY.md path |

## ✅ Verification

**Confirm successful setup:**

```bash
cd docs

# Build test
mdbook build
# Output: book/ directory created with 7.4 MB of files

# Check structure
ls -la book/index.html     # Should exist
ls -la src/SUMMARY.md      # Should exist
ls -la theme/vapora-custom.css  # Should exist

# Serve test
mdbook serve &
# Should output: Serving on http://0.0.0.0:3000
```
