or books.

## Contents
- [Installation](#installation)
- [Options](#options)
- [Numbered chapters](#numbered-chapters)
## Installation
First download this theme to your `themes` directory:
```bash
$ cd themes
$ git clone https://github.com/getzola/book.git
```
and then enable it in your `config.toml`:
```toml
theme = "book"
# Optional, if you want search
build_search_index = true
```
## Usage
Book will generate a book from the files you place in the `content` directory. Your book
can have two levels of hierarchy: chapters and subchapters.
Each chapter should be a `section` within the Gutenberg site and should have an `_index.md`
file that sets its `weight` front-matter variable to its chapter number. For example,
chapter 2 should have `weight = 2`. Additionally, each chapter should also set the
`sort_by = "weight"` in its front matter.
Each subchapter should be a `page` and should have its `weight` variable set to the subchapter
number. For example, subchapter 3.4 should have `weight = 4`.
Finally, you should create an `_index.md` file and set the `redirect_to` front-matter variable
to redirect to the first section of your content. For example, if your first section has the
slug `introduction`, then you would set `redirect_to = "introduction"`.
## Options
### Numbered chapters
By default, the `book` theme will number the chapters and pages in the left menu.
You can disable that by setting the `book_number_chapters` in `extra`:
```toml
book_number_chapters = false
```
