 ## Send feedback
 We’ve done our best to test but your feedback is really important. If you encounter problems or have feedback about GitBook products (GitBook.com, GitBook Editor, or the Toolchain), please log an issue in the [GitbookIO/feedback](https://github.com/GitbookIO/feedback/issues) repository.
 ## Reporting Bugs
 If you run into any weird behavior while using GitBook, feel free to open a new issue in this repository! To be most helpful, please include the steps to reproduce the bug as best you can, including the output of command `gitbook -V`.
 ## Asking Questions
 Questions are very welcome :smile:! Previous questions that folks have asked are tagged with a [`question`](https://github.com/GitBookIO/gitbook/issues?q=is%3Aissue+is%3Aclosed+label%3Aquestion) label, so before opening a new issue double-check that someone hasn't asked it before. But if you don't see anything, or if you're not sure if it's the same, err on the side of asking!
 We've also got a [GitBook Community Slack](https://slack.gitbook.com/) where you can ask questions and get answers from other people using GitBook.
 ## Submitting Pull Requests
 All pull requests are super welcomed and greatly appreciated! Easy issues are marked with an [`easy-one`](https://github.com/GitBookIO/gitbook/issues?q=is%3Aopen+is%3Aissue+label%3Aeasy-one) label if you're looking for a simple place to get familiar with the code base.
 Please include tests and docs with every pull request!
 ## Running Tests
 To run the examples, you need to have the GitBook repository cloned to your computer. After that, you need to `cd` into the directory where you cloned it, and install the dependencies from `npm` using `yarn`.
 ```
 $ yarn install
 ```
 Then you'll need to bootstrap it:
 ```
 $ npm run bootstrap
 ```
 Which will also compile the source files. Then run the tests with:
 ```
 $ npm test
 ```

-You can serve a repository as a book using:
+GitBook is a command line tool (and Node.js library) for building beautiful books using GitHub/Git and Markdown (or AsciiDoc). Here is an example: [ReduxJS documentation](http://redux.js.org/).
-```
+You can publish and host books easily online using [gitbook.com](https://www.gitbook.com). A desktop editor is [also available](https://www.gitbook.com/editor).
 $ gitbook serve ./repository
 ```
-Or simply build the static website using:
+Check out the [GitBook Community Slack Channel](https://slack.gitbook.com), Stay updated by following [@GitBookIO](https://twitter.com/GitBookIO) on Twitter or [GitBook](https://www.facebook.com/gitbookcom) on Facebook.
-```
+Complete documentation is available at [toolchain.gitbook.com](http://toolchain.gitbook.com/).
 $ gitbook build ./repository --output=./outputFolder
 ```
-Options for commands `build` and `serve` are:
+## Getting started
-```
+GitBook can be used either on your computer for building local books or on GitBook.com for hosting them. To get started, check out [the installation instructions in the documentation](docs/setup.md).
 -o, --output <directory>  Path to output directory, defaults to ./_book
 -f, --format <name>       Change generation format, defaults to site, availables are: site, page, ebook, json
 --config <config file>    Configuration file to use, defaults to book.js or book.json
 ```
-GitBook loads the default configuration from a `book.json` file in the repository if it exists.
+## Usage examples
-Here are the options that can be stored in this file:
+GitBook can be used to create book, public documentation, enterprise manual, thesis, research papers, etc.
-```js
+You can find a [list of real-world examples](docs/examples.md) in the documentation.

 You can publish your books to our index by visiting [GitBook.io](http://www.gitbook.io)
 ## Output Formats
 GitBook can generate your book in the following formats:
 * **Static Website**: This is the default format. It generates a complete interactive static website that can be, for example, hosted on GitHub Pages.
 * **eBook**: A complete eBook with exercise solutions at the end of the book. Generate this format using: ```gitbook ebook ./myrepo```. You need to have [ebook-convert](http://manual.calibre-ebook.com/cli/ebook-convert.html) installed. The output format could be **PDF**, **ePub** or **MOBI**.
 * **Single Page**: The book will be stored in a single printable HTML page. This format is used for conversion to PDF or eBook. Generate this format using: ```gitbook build ./myrepo -f page```.
 * **JSON**: This format is used for debugging or extracting metadata from a book. Generate this format using: ```gitbook build ./myrepo -f json```.
 ## Book Format
 A book is a Git repository containing at least 2 files: `README.md` and `SUMMARY.md`.
 #### README.md
 Typically, this should be the introduction for your book. It will be automatically added to the final summary.
 #### SUMMARY.md
 The `SUMMARY.md` defines your book's structure. It should contain a list of chapters, linking to their respective pages.
 Example:
 ```
 # Summary
 This is the summary of my book.
 * [section 1](section1/README.md)
    * [example 1](section1/example1.md)
    * [example 2](section1/example2.md)
 * [section 2](section2/README.md)
    * [example 1](section2/example1.md)
 ```
 Files that are not included in `SUMMARY.md` will not be processed by `gitbook`.
 #### Exercises
 A book can contain interactive exercises (currently only in Javascript but Python and Ruby are coming soon ;) ). An exercise is a code challenge provided to the reader, who is given a code editor to write a solution which is checked against the book author's validation code.
 An exercise is defined by 4 simple parts:
 * Exercise **Message**/Goals (in markdown/text)
 * **Initial** code to show to the user, providing a starting point
 * **Solution** code, being a correct solution to the exercise
 * **Validation** code that tests the correctness of the user's input
 Exercises need to start and finish with a separation bar (```---``` or ```***```). It should contain 3 code elements (**base**, **solution** and **validation**). It can contain a 4th element that provides **context** code (functions, imports of libraries, etc which shouldn't be displayed to the user).
    ---
    Define a variable `x` equal to 10.
    ```js
    var x =
    ```
    ```js
    var x = 10;
    ```
    ```js
    assert(x == 10);
    ```
    ```js
    // This is context code available everywhere
    // The user will be able to call magicFunc in his code
    function magicFunc() {
        return 3;
    }
    ```
    ---
 #### Multi-Languages
 GitBook supports building books written in multiple languages. Each language should be a sub-directory following the normal GitBook format, and a file named `LANGS.md` should be present at the root of the repository with the following format:
 ```
 * [English](en/)
 * [French](fr/)
 * [Español](es/)
 ```
 You can see a complete example with the [Learn Git](https://github.com/GitbookIO/git) book.
 #### Ignoring files & folders
 GitBook will read the `.gitignore`, `.bookignore` and `.ignore` files to get a list of files and folders to skip. (The format inside those files follows the same convention as `.gitignore`)
 #### Cover
 A cover image can be set by creating a file: **/cover.jpg**.
 The best resolution is **1800x2360**. The generation of the cover can be done automatically using the plugin [autocover](https://github.com/GitbookIO/plugin-autocover).
 A small version of the cover can also be set by creating a file: **/cover_small.jpg**.
 #### Publish your book
 The platform [GitBook.io](https://www.gitbook.io/) is like an "Heroku for books": you can create a book on it (public, paid, or private) and update it using **git push**.
 #### Plugins
 Plugins can used to extend your book's functionality. Read [GitbookIO/plugin](https://github.com/GitbookIO/plugin) for more information about how to build a plugin for GitBook.
 ##### Default plugins:
 * [mathjax](https://github.com/GitbookIO/plugin-mathjax): displays mathematical notation in the book.
 * [mixpanel](https://github.com/GitbookIO/plugin-mixpanel): Mixpanel tracking for your book
 ##### Other plugins:
 * [Google Analytics](https://github.com/GitbookIO/plugin-ga): Google Analytics tracking for your book

 * [Autocover](https://github.com/GitbookIO/plugin-autocover): Generate a cover for your book
 * [Transform annoted quotes to notes](https://github.com/erixtekila/gitbook-plugin-richquotes): Allow extra markdown markup to render blockquotes as nice notes
 * [Send code to console](https://github.com/erixtekila/gitbook-plugin-toconsole): Evaluate javascript block in the browser inspector's console
 * [Revealable sections](https://github.com/mrpotes/gitbook-plugin-reveal): Reveal sections of the page using buttons made from the first title in each section
 * [Markdown within HTML](https://github.com/mrpotes/gitbook-plugin-nestedmd): Process markdown within HTML blocks - allows custom layout options for individual pages
 * [Bootstrap JavaScript plugins](https://github.com/mrpotes/gitbook-plugin-bootstrapjs): Use the [Bootstrap JavaScript plugins](http://getbootstrap.com/javascript) in your online GitBook
 * [Piwik Open Analytics](https://github.com/emmanuel-keller/gitbook-plugin-piwik): Piwik Open Analytics tracking for your book
 * [Heading Anchors](https://github.com/rlmv/gitbook-plugin-anchors): Add linkable Github-style anchors to headings
 * [JSBin](https://github.com/jcouyang/gitbook-plugin-jsbin): Ebedded jsbin frame into your book
 #### Debugging
 You can use the environment variable `DEBUG=true` to get better error messages (with stack trace). For example:
 ```
 $ export DEBUG=true
 $ gitbook build ./
 ```

 # Plugin Architecture
 A GitBook plugin is a NPM package that follows a defined convention.
 `gitbook-plugin` is a command line utility to help you create, test and release plugins.
 ### Bootstrap your first plugin
 Install `gitbook-plugin` from NPM:
 ```
 $ npm install gitbook-plugin -g
 ```
 Then create your plugin:
 ```
 $ gitbook-plugin create
 ```
 You will be asked for a plugin name, and a few other things to complete the creation process.

 # Components
 ## Injection
 Plugins can inject components by registering React components to some roles.
 #### Register a components
 During the initialization phase of your plugin, dispatch the `GitBook.registerComponent` action:
 ```js
 dispatch(GitBook.registerComponent(MyCustomButton, { role: 'toolbar:buttons:left' }));
 ```
 #### Roles
 Custom roles can be use for interopability with other plugins, but GitBook and the default theme set a convention for common roles:
 | Role | Description | Props |
 | ---- | ----------- | ----- |
 | `page:container` | DIV container for the page's content | `{ page: Page }` |
 | `summary:container` | DIV container for the whole summary | `{ summary: Summary }` |
 | `summary:parts` | DIV container for summary's parts | `{ parts: List<SummaryPart> }` |
 | `summary:part` | DIV for a specific part | `{ part: SummaryPart }` |
 | `summary:articles` | UL container for a part's articles | `{ articles: List<SummaryArticle> }` |
 | `summary:article` | LI for a specific article | `{ article: SummaryArticle }` |
 ## Default Components
 #### `GitBook.Head`
 Extends the meta tags of the page. This is an alias for [react-helmet](https://github.com/nfl/react-helmet).
 ```js
 <GitBook.Head
    title="My page"
  />
 ```
 #### `GitBook.ImportCSS`
 Import a CSS file by resolving the path correctly according to the current page:
 ```js
 <GitBook.ImportCSS href="myfile.css" />
 ```
 #### `GitBook.ImportJS`
 Import a JS file by resolving the path correctly according to the current page:
 ```js
 <GitBook.ImportJS src="mylib.js" />
 ```
 #### `GitBook.InjectedComponent`
 Inject a component matching a specific role:
 ```js
 <GitBook.InjectedComponent matching={{ role: 'mycustomrole' }} props={{ someProp: 1 }}>
    <b>Inner content</b>
 </GitBook.InjectedComponent>
 ```
 #### `GitBook.InjectedComponentSet`
 Same API as `InjectedComponentSet` but render the matching components in chain instead of composed:
 ```js
 <GitBook.InjectedComponentSet matching={{ role: 'mytoolbar' }} />
 ```
 **Warning:** Children are discarded.
 #### `GitBook.FlexLayout` and `GitBook.FlexBox`
 A simple wrapper that provides a Flexbox layout with the given direction and style. Any additional props you set on the Flexbox are rendered.
 ```js
 <GitBook.FlexLayout column>
    <GitBook.FlexBox>First column</GitBook.FlexBox>
    <GitBook.FlexBox>Second column</GitBook.FlexBox>
 </GitBook.FlexLayout>

 # Connect to the context
 `GitBook.connect(Component, [mapStateToProps], [mapActionsToProps])` connects a react component to the GitBook context.
 It does not modify the component class passed to it.
 Instead, it returns a new, connected component class, for you to use.
 ### `mapStateToProps(state, [ownProps]): stateProps`
 If specified, the component will subscribe to GitBook store updates. Any time it updates, `mapStateToProps` will be called. Its result must be a plain object, and it will be merged into the component’s props.
 If you omit it, the component will not be subscribed to the GitBook store. If `ownProps` is specified as a second argument, its value will be the props passed to your component, and `mapStateToProps` will be additionally re-invoked whenever the component receives new props (e.g. if props received from a parent component have shallowly changed, and you use the `ownProps` argument, `mapStateToProps` is re-evaluated).
 For example to render the title of the current page:
 ```js
 const GitBook = require('gitbook-core');
 let PageTitle = React.createClass({
    render() {
        const { page } = this.props;
        return <h1>{page.title}</h1>;
    }
 });
 function mapStateToProps(state) {
    return { page: state.page };
 }
 PageTitle = GitBook.connect(PageTitle, mapStateToProps);

 # Internationalize your plugin
 GitBook has built-in support for internationalization. Plugins can register new languages and provide the right messages for different languages.
 ### Register locale and messages
 The first step is to register messages for a language:
 ```js
 module.exports = GitBook.createPlugin({
    init: (dispatch, getState, { I18n }) => {
        dispatch(I18n.registerLocale('en-US', {
            MY_PLUGIN_MESSAGE: 'Hello World'
        }));
    }
 });
 ```
 ### Render a message in a component
 `GitBook.connect` adds a `i18n` prop to access the internationalization:
 ```js
 const GitBook = require('gitbook-core');
 const { React } = GitBook;
 const MyButton = React.createClass({
    propTypes: {
        i18n: GitBook.Shapes.i18n
    },
    render() {
        const { i18n } = this.props;
        return (
            <GitBook.Button>
                {i18.t('MY_PLUGIN_MESSAGE')}
            </GitBook.Button>
        );
    }
 });
 module.exports = GitBook.connect(MyButton);

 # Navigation
 ### Listen to url change
 Listen for changes to the current location:
 ```js
 const onLocationChanged = (location) => {
    console.log(location.pathname);
    console.log(location.query);
    console.log(location.hash);
 };
 module.exports = GitBook.createPlugin({
    init: (dispatch, getState, { Navigation }) => {

 # Node APIs
 GitBooks provides different Node APIs and contexts to plugins. These APIs can vary according to the GitBook version being used, your plugin should specify the `engines.gitbook` field in `package.json` accordingly.
 #### Book instance
 The `Book` interface is the central point of GitBook, it centralize all access read methods.
 ```js
 // Read configuration from book.json
 var value = book.config.get('title', 'Default Value');
 // Resolve a filename to an absolute path
 var filepath = book.resolve('README.md');
 // Render an inline markup string
 book.renderInline('markdown', 'This is **Markdown**')
    .then(function(str) { ... })
 // Render a markup string (block mode)
 book.renderBlock('markdown', '* This is **Markdown**')
    .then(function(str) { ... })
 ```
 #### Output instance
 The `Output` class represent the output/write process.
 ```js
 // Return root folder for the output
 var root = output.root();
 // Resolve a file in the output folder
 var filepath = output.resolve('myimage.png');
 // Convert a filename to an URL (returns a path to an html file)
 var fileurl = output.toURL('mychapter/README.md');
 // Write a file in the output folder
 output.writeFile('hello.txt', 'Hello World')
    .then(function() { ... });
 // Copy a file to the output folder
 output.copyFile('./myfile.jpg', 'cover.jpg')
    .then(function() { ... });
 // Verify that a file exists
 output.hasFile('hello.txt')
    .then(function(exists) { ... });
 ```
 #### Page instance
 A page instance represent the current parsed page.
 ```js
 // Title of the page (from SUMMARY)
 page.title
 // Content of the page (Markdown/Asciidoc/HTML according to the stage)
 page.content
 // Relative path in the book
 page.path
 // Absolute path to the file
 page.rawPath
 // Type of parser used for this file
 page.type ('markdown' or 'asciidoc')
 ```
 #### Context for Blocks and Filters
 Blocks and filters have access to the same context, this context is bind to the template engine execution:
 ```js
 {
    // Current templating syntax
    "ctx": {
        // For example, after a {% set message = "hello" %}
        "message": "hello"
    },
    // Book instance
    "book" <Book>,
    // Output instance
    "output": <Output>
 }
 ```
 For example a filter or block function can access the current book using: `this.book`.
 #### Context for Hooks
 Hooks only have access to the `<Book>` instance using `this.book`.

 # Configuration
 GitBook allows you to customize your book using a flexible configuration. These options are specified in a `book.json` file. For authors unfamiliar with the JSON syntax, you can validate the syntax using tools such as [JSONlint](http://jsonlint.com).
 ### General Settings
 | Variable | Description |
 | -------- | ----------- |
 | `root` | Path to the root folder containing all the book's files, except `book.json`|
 | `structure` | To specify paths for Readme, Summary, Glossary etc. See [Structure paragraph](#structure). |
 | `title` | Title of your book, default value is extracted from the README. On GitBook.com this field is pre-filled. |
 | `description` | Description of your book, default value is extracted from the README. On GitBook.com this field is pre-filled. |

 | `direction` | Text's direction. Can be `rtl` or `ltr`, the default value depends on the value of `language` |
 | `gitbook` | Version of GitBook that should be used. Uses the [SemVer](http://semver.org) specification and accepts conditions like `">= 3.0.0"` |
 ### Plugins
 Plugins and their configurations are specified in the `book.json`. See [the plugins section](plugins/README.md) for more details.
 Since version 3.0.0, GitBook can use themes. See [the theming section](themes/README.md) for more details.
 | Variable | Description |
 | -------- | ----------- |
 | `plugins` | List of plugins to load |
 | `pluginsConfig` |Configuration for plugins |
 ### Structure
 In addition to the `root` variable, you can tell Gitbook the name of the files for Readme, Summary, Glossary, Languages (instead of using the default names such as `README.md`).
 These files must be at the root of your book (or the root of every language book). Paths such as `dir/MY_README.md` are not accepted.

 # Generating eBooks and PDFs
 GitBook can generates a website, but can also output content as ebook (ePub, Mobi, PDF).
 ```
 # Generate a PDF file
 $ gitbook pdf ./ ./mybook.pdf
 # Generate an ePub file
 $ gitbook epub ./ ./mybook.epub
 # Generate a Mobi file
 $ gitbook mobi ./ ./mybook.mobi
 ```
 ### Installing ebook-convert
 `ebook-convert` is required to generate ebooks (epub, mobi, pdf).
 ##### GNU/Linux
 Install the [Calibre application](https://calibre-ebook.com/download).
 ```
 $ sudo aptitude install calibre
 ```
 In some GNU/Linux distributions node is installed as nodejs, you need to manually create a symlink:
 ```
 $sudo ln -s /usr/bin/nodejs /usr/bin/node
 ```
 ##### OS X
 Download the [Calibre application](https://calibre-ebook.com/download). After moving the `calibre.app` to your Applications folder create a symbolic link to the ebook-convert tool:
 ```
 $ sudo ln -s ~/Applications/calibre.app/Contents/MacOS/ebook-convert /usr/bin
 ```
 You can replace `/usr/bin` with any directory that is in your $PATH.
 ### Cover
 Covers are used for all the ebook formats. You can either provide one yourself, or generate one using the [autocover plugin](https://plugins.gitbook.com/plugin/autocover).
 To provide a cover, place a **`cover.jpg`** file at the root directory of your book. Adding a **`cover_small.jpg`** will specify a smaller version of the cover. The cover should be a **JPEG** file.
 A good cover should respect the following guidelines:
 * Size of 1800x2360 pixels for `cover.jpg`, 200x262 for `cover_small.jpg`
 * No border
 * Clearly visible book title
 * Any important text should be visible in the small version

 # GitBook FAQ
 This page gathers common questions and answers concerning the GitBook format and toolchain.
 Questions about GitBook.com and the Editor are gather into the [help.gitbook.com's FAQ](http://help.gitbook.com/faq.html).
 #### How can I host/publish my book?
 Books can easily be published and hosted on [GitBook.com](https://www.gitbook.com). But GitBook output can be hosted on any static file hosting solution.
 #### What can I use to edit my content?
 Any text editor should work! But we advise using the [GitBook Editor](https://www.gitbook.com/editor). [GitBook.com](https://www.gitbook.com) also provides a web version of this editor.
 ---
 #### Does GitBook supports RTL/bi-directional text ?
 The GitBook format supports right to left, and bi-directional writing. To enable it, you either need to specify a language (ex: `ar`), or force GitBook to use RTL in your `book.json`:
 ```json
 {
    "language": "ar",
    "direction": "rtl"
 }
 ```
 With version 3.0 of GitBook, it's automatically detected according to the content.
 _Note that, while the output book will indeed respect RTL, the Editor doesn't support RTL writing yet_.
 #### Should I use an `.html` or `.md` extensions in my links?
 You should always use paths and the `.md` extensions when linking to your files, GitBook will automatically replace these paths by the appropriate link when the pointing file is referenced in the Table of Contents.
 #### Can I create a GitBook in a sub-directory of my repository?
 Yes, GitBooks can be created in [sub-directories](structure.md#subdirectory). GitBook.com and the CLI also looks by default in a series of [folders](structure.md).
 #### Does GitBook supports RTL languages?
 Yes, GitBook automatically detect the direction in your pages (`rtl` or `ltr`) and adjust the layout accordingly. The direction can also be specified globally in the [book.json](config.md).
 ---
 #### Does GitBook support Math equations?
 GitBook supports math equations and TeX thanks to plugins. There are currently 2 official plugins to display math: [mathjax](https://plugins.gitbook.com/plugin/mathjax) and [katex](https://plugins.gitbook.com/plugin/katex).
 #### Can I customize/theme the output?

 # Multi-Languages
 GitBook supports building books written in multiple languages. Each language should be a sub-directory following the normal GitBook format, and a file named `LANGS.md` should be present at the root of the repository with the following format:
 ```markdown
 # Languages
 * [English](en/)
 * [French](fr/)
 * [Español](es/)
 ```
 ### Configuration for each language
 When a language book (ex: `en`) has a `book.json`, its configuration will extend the main configuration.
 The only exception is plugins, plugins are specified globally, and language specific plugins cannot be specified.

 # Glossary
 Allows you to specify terms and their respective definitions to be displayed as annotations. Based on those terms, GitBook will automatically build an index and highlight those terms in pages.
 The `GLOSSARY.md` format is a list of `h2` headings, along with a description paragraph:
 ```markdown
 ## Term
 Definition for this term
 ## Another term
 With it's definition, this can contain bold text
 and all other kinds of inline markup ...

 # Pages and Summary
 ### Summary
 GitBook uses a `SUMMARY.md` file to define the structure of chapters and subchapters of the book. The `SUMMARY.md` file is used to generate the book's table of contents.
 The format of `SUMMARY.md` is just a list of links. The link's title is used as the chapter's title, and the link's target is a path to that chapter's file.
 Adding a nested list to a parent chapter will create subchapters.
 ##### Simple example
 ```markdown
 # Summary
 * [Part I](part1/README.md)
    * [Writing is nice](part1/writing.md)
    * [GitBook is nice](part1/gitbook.md)
 * [Part II](part2/README.md)
    * [We love feedback](part2/feedback_please.md)
    * [Better tools for authors](part2/better_tools.md)
 ```
 Each chapter has a dedicated page (`part#/README.md`) and is split into subchapters.
 ##### Anchors
 Chapters in the Table of Contents can be pointing to specific part of a file using anchor.
 ```markdown
 # Summary
 ### Part I
 * [Part I](part1/README.md)
    * [Writing is nice](part1/README.md#writing)
    * [GitBook is nice](part1/README.md#gitbook)
 * [Part II](part2/README.md)
    * [We love feedback](part2/README.md#feedback)
    * [Better tools for authors](part2/README.md#tools)
 ```
 ##### Parts
 The Table of Contents can be divided into parts separated by headings or horizontal lines:
 ```markdown
 # Summary
 ### Part I
 * [Writing is nice](part1/writing.md)
 * [GitBook is nice](part1/gitbook.md)
 ### Part II
 * [We love feedback](part2/feedback_please.md)
 * [Better tools for authors](part2/better_tools.md)
 ----
 * [Last part without title](part3/title.md)
 ```
 Parts are just groups of chapters and do not have dedicated pages, but according to the theme, it will show in the navigation.
 ### Pages
 #### Markdown syntax
 Most of the files for GitBook use the Markdown syntax by default. GitBook infers your pages's structure from it. The syntax used is similar to the [GitHub Flavored Markdown syntax](https://guides.github.com/features/mastering-markdown/). One can also opt for the [AsciiDoc syntax](asciidoc.md).
 ##### Example of a chapter file
 ```markdown
 # Title of the chapter
 This is a great introduction.
 ## Section 1
 Markdown will dictates _most_ of your **book's structure**
 ## Section 2
 ...
 ```
 #### Front Matter
 Pages can contain an optional front matter. It can be used to define the page's description. The front matter must be the first thing in the file and must take the form of valid YAML set between triple-dashed lines. Here is a basic example:
 ```yaml
 ---
 description: This is a short description of my page
 ---
 # The content of my page
 ...
 ```
 The front matter can define variables of your own, they will be added to the [page variable](templating/variables.md) so you can use them in your templating.

 # Plugins
 Plugins are the best way to extend GitBook functionalities (ebook and website). There exist plugins to do a lot of things: bring math formulas display support, track visits using Google Analytics, etc.
 ### How to find plugins?
 Plugins can be easily searched on [plugins.gitbook.com](https://plugins.gitbook.com).
 ### How to install a plugin?
 Once you find a plugin that you want to install, you need to add it to your `book.json`:
 ```
 {
    "plugins": ["myPlugin", "anotherPlugin"]
 }
 ```
 You can also specify a specific version using: `"myPlugin@0.3.1"`. By default GitBook will resolve the latest version of the plugin compatbile with the current GitBook version.
 ### GitBook.com
 Plugins are automatically installed on [GitBook.com](https://www.gitbook.com). Locally, run `gitbook install` to install and prepare all plugins for your books.
 ### Configuring plugins
 Plugins specific configurations are stored in `pluginsConfig`. You have to refer to the documentation of the plugin itself for details about the available options.

 # Context and APIs
 GitBooks provides different APIs and contexts to plugins. These APIs can vary according to the GitBook version being used, your plugin should specify the `engines.gitbook` field in `package.json` accordingly.
 #### Book instance
 The `Book` class is the central point of GitBook, it centralize all access read methods. This class is defined in [book.js](https://github.com/GitbookIO/gitbook/blob/master/book.js).
 ```js
 // Read configuration from book.json
 var value = book.config.get('title', 'Default Value');
 // Resolve a filename to an absolute path
 var filepath = book.resolve('README.md');
 // Render an inline markup string
 book.renderInline('markdown', 'This is **Markdown**')
    .then(function(str) { ... })
 // Render a markup string (block mode)
 book.renderBlock('markdown', '* This is **Markdown**')
    .then(function(str) { ... })
 ```
 #### Output instance
 The `Output` class represent the output/write process.
 ```js
 // Return root folder for the output
 var root = output.root();
 // Resolve a file in the output folder
 var filepath = output.resolve('myimage.png');
 // Convert a filename to an URL (returns a path to an html file)
 var fileurl = output.toURL('mychapter/README.md');
 // Write a file in the output folder
 output.writeFile('hello.txt', 'Hello World')
    .then(function() { ... });
 // Copy a file to the output folder
 output.copyFile('./myfile.jpg', 'cover.jpg')
    .then(function() { ... });
 // Verify that a file exists
 output.hasFile('hello.txt')
    .then(function(exists) { ... });
 ```
 #### Page instance
 A page instance represent the current parsed page.
 ```js
 // Title of the page (from SUMMARY)
 page.title
 // Content of the page (Markdown/Asciidoc/HTML according to the stage)
 page.content
 // Relative path in the book
 page.path
 // Absolute path to the file
 page.rawPath
 // Type of parser used for this file
 page.type ('markdown' or 'asciidoc')
 ```
 #### Context for Blocks and Filters
 Blocks and filters have access to the same context, this context is bind to the template engine execution:
 ```js
 {
    // Current templating syntax
    "ctx": {
        // For example, after a {% set message = "hello" %}
        "message": "hello"
    },
    // Book instance
    "book" <Book>,
    // Output instance
    "output": <Output>
 }
 ```
 For example a filter or block function can access the current book using: `this.book`.
 #### Context for Hooks
 Hooks only have access to the `<Book>` instance using `this.book`.

 # Extend Blocks
 Extending templating blocks is the best way to provide extra functionalities to authors.
 The most common usage is to process the content within some tags at runtime. It's like [filters](./filters.md), but on steroids because you aren't confined to a single expression.
 ### Defining a new block
 Blocks are defined by the plugin, blocks is a map of name associated with a block descriptor. The block descriptor needs to contain at least a `process` method.
 ```js
 module.exports = {
    blocks: {
        tag1: {
            process: function(block) {
                return "Hello "+block.body+", How are you?";
            }
        }
    }
 };
 ```
 The `process` should return the html content that will replace the tag. Refer to [Context and APIs](./api.md) to learn more about `this` and GitBook API.
 ### Handling block arguments
 Arguments can be passed to blocks:
 ```
 {% tag1 "argument 1", "argument 2", name="Test" %}
 This is the body of the block.
 {% endtag1 %}
 ```
 And arguments are easily accessible in the `process` method:
 ```js
 module.exports = {
    blocks: {
        tag1: {
            process: function(block) {
                // block.args equals ["argument 1", "argument 2"]
                // block.kwargs equals { "name": "Test" }
            }
        }
    }
 };
 ```
 ### Handling sub-blocks
 A defined block can be parsed into different sub-blocks, for example let's consider the source:
 ```
 {% myTag %}
    Main body
    {% subblock1 %}
    Body of sub-block 1
    {% subblock 2 %}
    Body of sub-block 1
 {% endmyTag %}

 # Create and publish a plugin
 A GitBook plugin is a node package published on NPM that follow a defined convention.
 ## Structure
 #### package.json
 The `package.json` is a manifest format for describing **Node.js modules**. GitBook plugins are built on top of Node modules. It declares dependencies, version, ownership, and other information required to run a plugin in GitBook. This document describes the schema in detail.
 A plugin manifest `package.json` can also contain details about the required configuration. The configuration schema is defined in the `gitbook` field of the `package.json` (This field follow the [JSON-Schema](http://json-schema.org) guidelines):
 ```js
 {
    "name": "gitbook-plugin-mytest",
    "version": "0.0.1",
    "description": "This is my first GitBook plugin",
    "engines": {
        "gitbook": ">1.x.x"
    },
    "gitbook": {
        "properties": {

                "description": "It defines my awesome config!"
            }
        }
    }
 }
 ```
 You can learn more about `package.json` from the [NPM documentation](https://docs.npmjs.com/files/package.json).
 The **package name** must begin with `gitbook-plugin-` and the **package engines** should contains `gitbook`.
 #### index.js
 The `index.js` is main entry point of your plugin runtime:
 ```js
 module.exports = {
    // Map of hooks
    hooks: {},
    // Map of new blocks
    blocks: {},
    // Map of new filters
    filters: {}
 };
 ```
 ## Publish your plugin
 GitBook plugins can be published on [NPM](https://www.npmjs.com).
 To publish a new plugin, you need to create an account on [npmjs.com](https://www.npmjs.com) then publish it from the command line:
 ```
 $ npm publish

 ## Private plugins
 Private plugins can be hosted on GitHub and included using `git` urls:

 # Extend Filters
 Filters are essentially functions that can be applied to variables. They are called with a pipe operator (`|`) and can take arguments.
 ```
 {{ foo | title }}
 {{ foo | join(",") }}
 {{ foo | replace("foo", "bar") | capitalize }}
 ```
 ### Defining a new filter
 Plugins can extend filters by defining custom functions in their entry point under the `filters` scope.
 A filter function takes as first argument the content to filter, and should return the new content.
 Refer to [Context and APIs](./api.md) to learn more about `this` and GitBook API.
 ```js
 module.exports = {
    filters: {
        hello: function(name) {
            return 'Hello '+name;
        }
    }
 };
 ```
 The filter `hello` can then be used in the book:
 ```
 {{ "Aaron"|hello }}, how are you?
 ```
 ### Handling block arguments
 Arguments can be passed to filters:
 ```
 Hello {{ "Samy"|fullName("Pesse", man=true}} }}
 ```
 Arguments are passed to the function, named-arguments are passed as a last argument (object).
 ```js
 module.exports = {
    filters: {
        fullName: function(firstName, lastName, kwargs) {
            var name = firstName + ' ' + lastName;

 # Hooks
 Hooks is a method of augmenting or altering the behavior of the process, with custom callbacks.
 ### List of hooks
 ### Relative to the global pipeline
 | Name | Description | Arguments |
 | ---- | ----------- | --------- |
 | `init` | Called after parsing the book, before generating output and pages. | None |
 | `finish:before` | Called after generating the pages, before copying assets, cover, ... | None |
 | `finish` | Called after everything else. | None |
 ### Relative to the page pipeline
 > It is recommended using [templating](./templating.md) to extend page parsing.
 | Name | Description | Arguments |
 | ---- | ----------- | --------- |
 | `page:before` | Called before running the templating engine on the page | Page Object |
 | `page` | Called before outputting and indexing the page. | Page Object |
 ##### Page Object
 ```js
 {
    // Parser named
    "type": "markdown",
    // File Path relative to book root
    "path": "page.md",
    // Absolute file path
    "rawpath": "/usr/...",
    // Title of the page in the SUMMARY
    "title": "",
    // Content of the page
    // Markdown/Asciidoc in "page:before"
    // HTML in "page"
    "content": "# Hello"
 }
 ```
 ##### Example to add a title
 In the `page:before` hook, `page.content` is the markdown/asciidoc content.
 ```js
 {
    "page:before": function(page) {
        page.content = "# Title\n" +page.content;
        return page;
    }
 }
 ```
 ##### Example to replace some html
 In the `page` hook, `page.content` is the HTML generated from the markdown/asciidoc conversion.
 ```js
 {
    "page": function(page) {
        page.content = page.content.replace("<b>", "<strong>")
            .replace("</b>", "</strong>");
        return page;
    }
 }
 ```
 ### Asynchronous Operations
 Hooks callbacks can be asynchronous and return promises.
 Example:
 ```js
 {
    "init": function() {
        return writeSomeFile()
        .then(function() {
            return writeAnotherFile();

 # Setup and Installation of GitBook
 Getting GitBook installed and ready-to-go should only take a few minutes.
 ### GitBook.com
 [GitBook.com](https://www.gitbook.com) is an easy to use solution to write, publish and host books. It is the easiest solution for publishing your content and collaborating on it.
 It integrates well with the [GitBook Editor](https://www.gitbook.com/editor).
 ### Local Installation
 ##### Requirements
 Installing GitBook is easy and straightforward. Your system just needs to meet these two requirements:
 * NodeJS (v4.0.0 and above is recommended)
 * Windows, Linux, Unix, or Mac OS X
 ##### Install with NPM
 The best way to install GitBook is via **NPM**. At the terminal prompt, simply run the following command to install GitBook:
 ```
 $ npm install gitbook-cli -g
 ```
 `gitbook-cli` is an utility to install and use multiple versions of GitBook on the same system. It will automatically install the required version of GitBook to build a book.
 ##### Create a book
 GitBook can setup a boilerplate book:
 ```
 $ gitbook init
 ```
 If you wish to create the book into a new directory, you can do so by running `gitbook init ./directory`
 Preview and serve your book using:
 ```
 $ gitbook serve
 ```
 Or build the static website using:
 ```
 $ gitbook build
 ```
 ##### Install pre-releases
 `gitbook-cli` makes it easy to download and install other versions of GitBook to test with your book:
 ```
 $ gitbook fetch beta
 ```
 Use `gitbook ls-remote` to list remote versions available for install.
 ##### Debugging
 You can use the options `--log=debug` and `--debug` to get better error messages (with stack trace). For example:
 ```
 $ gitbook build ./ --log=debug --debug

 # Directory Structure
 GitBook uses a simple directory structure. All Markdown/Asciidoc files listed in the [SUMMARY](pages.md) will be transformed as HTML. Multi-Lingual books have a slightly [different structure](languages.md).
 A basic GitBook usually looks something like this:
 ```
 .
 ├── book.json
 ├── README.md
 ├── SUMMARY.md
 ├── chapter-1/
 |   ├── README.md
 |   └── something.md
 └── chapter-2/
    ├── README.md
    └── something.md
 ```
 An overview of what each of these does:
 | File | Description |
 | -------- | ----------- |
 | `book.json` | Stores [configuration](config.md) data (__optional__) |
 | `README.md` | Preface / Introduction for your book (**required**) |
 | `SUMMARY.md` | Table of Contents (See [Pages](pages.md)) (__optional__) |
 | `GLOSSARY.md` | Lexicon / List of terms to annotate (See [Glossary](lexicon.md)) (__optional__) |
 ### Static files and Images
 A static file is a file that is not listed in the `SUMMARY.md`. All static files, unless [ignored](#ignore), are copied to the output.
 ### Ignoring files & folders {#ignore}
 GitBook will read the `.gitignore`, `.bookignore` and `.ignore` files to get a list of files and folders to skip.
 The format inside those files, follows the same convention as `.gitignore`:
 ```
 # This is a comment
 # Ignore the file test.md
 test.md
 # Ignore everything in the directory "bin"
 bin/*
 ```
 ### Project integration with subdirectory {#subdirectory}
 For software projects, you can use a subdirectory (like `docs/`) to store the book for the project's documentation. You can configure the [`root` option](config.md) to indicate the folder where GitBook can find the book's files:
 ```
 .
 ├── book.json
 └── docs/
    ├── README.md
    └── SUMMARY.md
 ```
 With `book.json` containing:
 ```
 {
    "root": "./docs"
 }

 # AsciiDoc
 Since version `2.0.0`, GitBook can also accept AsciiDoc as an input format.
 Please refer to the [AsciiDoc Syntax Quick Reference](http://asciidoctor.org/docs/asciidoc-syntax-quick-reference/) for more informations about the format.
 Just like for markdown, GitBook is using some special files to extract structures: `README.adoc`, `SUMMARY.adoc`, `LANGS.adoc` and `GLOSSARY.adoc`.
 ### README.adoc
 This is the main entry of your book: the introduction. This file is **required**.
 ### SUMMARY.adoc
 This file defines the list of chapters and subchapters. Just like in Markdown, the `SUMMARY.adoc`'s format is simply a list of links, the name of the link is used as the chapter's name, and the target is a path to that chapter's file.
 Subchapters are defined simply by adding a nested list to a parent chapter.
 ```asciidoc
 = Summary
 . link:chapter-1/README.adoc[Chapter 1]
 .. link:chapter-1/ARTICLE1.adoc[Article 1]
 .. link:chapter-1/ARTICLE2.adoc[Article 2]
 ... link:chapter-1/ARTICLE-1-2-1.adoc[Article 1.2.1]

 . link:chapter-3/README.adoc[Chapter 3]
 . link:chapter-4/README.adoc[Chapter 4]
 .. Unfinished article
 . Unfinished Chapter
 ```
 ### LANGS.adoc
 For [Multi-Languages](./languages.md) books, this file is used to define the different supported languages and translations.
 This file is following the same syntax as the `SUMMARY.adoc`:
 ```asciidoc
 = Languages
 . link:en/[English]
 . link:fr/[French]
 ```
 ### GLOSSARY.adoc
 This file is used to define terms. [See the glossary section](./lexicon.md).
 ```asciidoc

 # Markdown
 Most of the examples from this documentation are in Markdown. Markdown is default parser for GitBook, but one can also opt for the [AsciiDoc syntax](asciidoc.md).
 Here’s an overview of Markdown syntax that you can use with GitBook (same as GitHub with some additions).
 ### Headings
 To create a heading, add one to six `#` symbols before your heading text. The number of # you use will determine the size of the heading.
 ```markdown
 # This is an <h1> tag
 ## This is an <h2> tag
 ###### This is an <h6> tag
 ```
 GitBook supports a nice way for explicitly setting the header ID. If you follow the header text with an opening curly bracket (separated from the text with a least one space), a hash, the ID and a closing curly bracket, the ID is set on the header. If you use the trailing hash feature of atx style headers, the header ID has to go after the trailing hashes. For example:
 ```markdown
 Hello {#id}
 -----
 # Hello {#id}
 # Hello # {#id}
 ```
 ### Paragraphs and Line Breaks {#paragraphs}
 A paragraph is simply one or more consecutive lines of text, separated by one or more blank lines. (A blank line is any line that looks like a blank line — a line containing nothing but spaces or tabs is considered blank.) Normal paragraphs should not be indented with spaces or tabs.
 ```
 Here's a line for us to start with.
 This line is separated from the one above by two newlines, so it will be a *separate paragraph*.
 ```
 ### Emphasis {#emphasis}
 ```markdown
 *This text will be italic*
 _This will also be italic_
 **This text will be bold**
 __This will also be bold__
 ~~This text will be crossed out.~~
 _You **can** combine them_
 ```
 ### Lists {#lists}
 Markdown supports ordered (numbered) and unordered (bulleted) lists.
 ##### Unordered
 Unordered lists use asterisks, pluses, and hyphens — interchangably — as list markers:
 ```markdown
 * Item 1
 * Item 2
  * Item 2a
  * Item 2b
 ```
 ##### Ordered
 Ordered lists use numbers followed by periods:
 ```markdown
 1. Item 1
 2. Item 2
 3. Item 3
   * Item 3a
   * Item 3b
 ```
 ### Links {#links}
 Markdown supports two style of links: inline and reference.
 A simple link can be created by surrounding the text with square brackets and the link URL with parentheses:
 ```markdown
 This is [an example](http://example.com/ "Title") inline link with a title.
 [This link](http://example.net/) has no title attribute.
 ```
 Links can point to relative paths, anchors or absolute urls.
 ### References
 There is another way to create links which does not interrupt the text flow. The URL and title are defined using a reference name and this reference name is then used in square brackets instead of the link URL:
 ```markdown
 This is [an example][id] reference-style link.
 ```
 Then, anywhere in the document, you define your link label like this, on a line by itself:
 ```markdown
 [id]: http://example.com/  "Optional Title Here"
 ```
 ### Images {#images}
 Images can be created in a similar way than links: just use an exclamation mark before the square brackets. The link text will become the alternative text of the image and the link URL specifies the image source:
 ```markdown
 An image: ![gras](img/image.jpg)
 ```
 ### Blockquotes {#blockquotes}
 A blockquote is started using the `>` marker followed by an optional space; all following lines that are also started with the blockquote marker belong to the blockquote. You can use any block-level elements inside a blockquote:
 ```markdown
 As Kanye West said:
 > We're living the future so
 > the present is our past.
 ```
 ### Tables {#tables}
 You can create tables by assembling a list of words and dividing them with hyphens `-` (for the first row), and then separating each column with a pipe `|`:
 ```markdown
 | First Header  | Second Header |
 | ------------- | ------------- |
 | Content Cell  | Content Cell  |
 | Content Cell  | Content Cell  |
 ```
 The pipes on either end of the table are optional. Cells can vary in width and do not need to be perfectly aligned within columns. There must be at least three hyphens in each column of the header row.
 ### Code {#code}
 Markdown supports two different code block styles. One uses lines indented with either four spaces or one tab whereas the other uses lines with tilde characters as delimiters – therefore the content does not need to be indented:
 ```markdown
 This is a sample code block.
    Continued here.
 ```
 ##### Fenced code blocks
 You can create fenced code blocks by placing triple backticks ` ``` ` before and after the code block. We recommend placing a blank line before and after code blocks to make the raw formatting easier to read.
    ```
    function test() {
      console.log("notice the blank line before this function?");
    }
    ```
 ##### Syntax highlighting
 You can add an optional language identifier to enable syntax highlighting in your fenced code block.
 For example, to syntax highlight Ruby code:
    ```ruby
    require 'redcarpet'
    markdown = Redcarpet.new("Hello World!")
    puts markdown.to_html
    ```
 ##### Inline code
 Text phrases can be marked up as code by surrounding them with backticks:
    Use `gitbook` to convert the `text` in markdown
    syntax to HTML.
 ### Footnotes
 GitBook supports a simple syntax for such footnotes. Footnotes are relative to each pages.
 ```markdown

 ### HTML
 GitBook supports use of raw HTML in your text, Markdown syntax in HTML is not processed:
 ```
 <div>
 Markdown here will not be **parsed**
 </div>
 ```
 ### Horizontal Rule
 Horizontal Rules can be inserted using three or more asterisks, dashes or underscores, optionally separated by spaces or tabs, on an otherwise blank line:
 ```markdown
 Three or more...
 ---
 Hyphens
 ***
 Asterisks
 ```
 ### Ignoring Markdown formatting
 You can tell GitBook to ignore (or escape) Markdown formatting by using `\` before the Markdown character.
 ```
 Let's rename \*our-new-project\* to \*our-old-project\*.

 # Templating
 GitBook uses the [Nunjucks templating language](https://mozilla.github.io/nunjucks/) to process pages and theme's templates.
 The Nunjucks syntax is very similar to **Jinja2** or **Liquid**. Its syntax uses surrounding braces `{ }` to mark content that needs to be processed.
 ### Variables
 A variable looks up a value from the template context. If you wanted to simply display a variable, you would use the `{{ variable }}` syntax. For example :
 ```twig
 My name is {{ name }}, nice to meet you
 ```
 This looks up username from the context and displays it. Variable names can have dots in them which lookup properties, just like JavaScript. You can also use the square bracket syntax.
 ```twig
 {{ foo.bar }}
 {{ foo["bar"] }}
 ```
 If a value is undefined, nothing is displayed. The following all output nothing if foo is undefined: `{{ foo }}`, `{{ foo.bar }}`, `{{ foo.bar.baz }}`.
 GitBook provides a set of [predefined variables](variables.md) from the context.
 ### Filters
 Filters are essentially functions that can be applied to variables. They are called with a pipe operator (`|`) and can take arguments.
 ```twig
 {{ foo | title }}
 {{ foo | join(",") }}
 {{ foo | replace("foo", "bar") | capitalize }}
 ```
 The third example shows how you can chain filters. It would display "Bar", by first replacing "foo" with "bar" and then capitalizing it.
 ### Tags
 ##### if
 `if` tests a condition and lets you selectively display content. It behaves exactly as JavaScript's `if` behaves.
 ```twig
 {% if variable %}
  It is true
 {% endif %}
 ```
 If variable is defined and evaluates to true, "It is true" will be displayed. Otherwise, nothing will be.
 You can specify alternate conditions with `elif` and `else`:
 ```twig
 {% if hungry %}
  I am hungry
 {% elif tired %}
  I am tired
 {% else %}
  I am good!
 {% endif %}
 ```
 ##### for
 `for` iterates over arrays and dictionaries.
 ```twig
 # Chapters about GitBook
 {% for article in glossary.terms['gitbook'].articles %}
 * [{{ article.title }}]({{ article.path }})
 {% endfor %}
 ```
 ##### set
 `set` lets you create/modify a variable.
 ```twig
 {% set softwareVersion = "1.0.0" %}
 Current version is {{ softwareVersion }}.
 [Download it](website.com/download/{{ softwareVersion }})
 ```
 ##### include and block
 Inclusion and inheritance is detailled in the [Content References](conrefs.md) section.
 ### Escaping
 If you want GitBook to ignore any of the special templating tags, you can use raw and anything inside of it will be output as plain text.
 ```twig
 {% raw %}
  this will {{ not be processed }}
 {% endraw %}
 ```

 # Builtin Templating Helpers
 GitBook provides a serie of builtin filters and blocks to help you write templates.
 ### Filters
 `value|default(default, [boolean])`
 If value is strictly undefined, return default, otherwise value. If boolean is true, any JavaScript falsy value will return default (false, "", etc)
 `arr|sort(reverse, caseSens, attr)`
 Sort arr with JavaScript's arr.sort function. If reverse is true, result will be reversed. Sort is case-insensitive by default, but setting caseSens to true makes it case-sensitive. If attr is passed, will compare attr from each item.
 ### Blocks
 `{% markdown %}Markdown string{% endmarkdown %}`
 Render inline markdown
 `{% asciidoc %}AsciiDoc string{% endasciidoc %}`
 Render inline asciidoc

 # Content References
 Content referencing (conref) is a convenient mechanism to reuse content from other files or books.
 ### Importing local files
 Importing an other file's content is easy using the `include` tag:
 ```
 {% include "./test.md" %}
 ```
 ### Importing file from another book
 GitBook can also resolve the include path by using git:
 ```
 {% include "git+https://github.com/GitbookIO/documentation.git/README.md#0.0.1" %}
 ```
 The format of git url is:
 ```
 git+https://user@hostname/owner/project.git/file#commit-ish
 ```
 The real git url part should finish with `.git`, the filename to import is extracted after the `.git` till the fragment of the url.
 The `commit-ish` can be any tag, sha, or branch which can be supplied as an argument to `git checkout`. The default is `master`.
 ### Inheritance
 Template inheritance is a way to make it easy to reuse templates. When writing a template, you can define "blocks" that child templates can override. The inheritance chain can be as long as you like.
 `block` defines a section on the template and identifies it with a name. Base templates can specify blocks and child templates can override them with new content.
 ```
 {% extends "./mypage.md" %}
 {% block pageContent %}
 # This is my page content
 {% endblock %}
 ```
 In the file `mypage.md`, you should specify the blocks that can be extended:
 ```
 {% block pageContent %}
 This is the default content
 {% endblock %}
 # License
 {% include "./LICENSE" %}
 ```

 # Theming
 Since version 3.0.0, GitBook can be easily themed. Books use the [theme-default](https://github.com/GitbookIO/theme-default) theme by default.
 > **Caution**: Custom theming can block some plugins from working correctly.
 ### Structure of a theme
 A theme is a plugin containing templates and assets. Overriding any individual template is optional, since themes always extend the default theme.
 | Folder | Description |
 | -------- | ----------- |
 | `_layouts` | Main folder containing all the templates |
 | `_layouts/website/page.html` | Template for a normal page |
 | `_layouts/ebook/page.html` | Template for a normal page during ebook generation (PDF, ePub, Mobi) |
 ### Extend/Customize theme in a book
 Authors can extend the templates of a theme directly from their book's source (without creating an external theme). Templates will be resolved in the `_layouts` folder of the book first, then in the installed plugins/themes.
 ### Extend instead of Forking
 When you want to make your theme changes available to multiple books, instead of forking the default theme, you can extend it using the [templating syntax](../templating/README.md):
 ```html
 {% extends template.self %}
 {% block body %}
    {{ super() }}
    ... This will be added to the "body" block
 {% endblock %}
 ```
 Take a look at the [API](https://github.com/GitbookIO/theme-api) theme for a more complete example.
 ### Publish a theme
 Themes are published as plugins ([see related docs](../plugins/README.md)) with a `theme-` prefix. For example the theme `awesome` will be loaded from the `theme-awesome` plugin, and then from the `gitbook-plugin-theme-awesome` NPM package.
