## Features

## Requirements

## Installation
Navigate to your hugo website root and run:
```
git submodule add https://github.com/alex-shpak/hugo-book themes/book
```

Then run hugo (or set `theme: book` in configuration file)
```
hugo server --theme book
```

## Menu
### File tree menu (default)
By default theme will render pages from `content/docs` section as menu in a tree structure.  
You can set `title` and `weight` in front matter of pages to adjust order and titles in menu.

### Leaf bundle menu
You can also use leaf bundle and content of it's `index.md` as 
menu.

Given you have this file structure
```
├── content
│   ├── docs
│   │   ├── page-one.md
│   │   └── page-two.md
│   └── posts
│       ├── post-one.md
│       └── post-two.md
```

Create file `content/docs/menu/index.md` with content
```md
---
headless: true
---

- [Book Example](/docs/)
  - [Page One](/docs/page-one)
  - [Page Two](/docs/page-two)
- [Blog](/posts)
```

And Enable it by settings `BookMenuBundle: /docs/menu` in Site configuration

- [Example menu](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/content/menu/index.md)
- [Example config file](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/config.yml)
