-## 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**: You need to have [ebook-convert](http://manual.calibre-ebook.com/cli/ebook-convert.html) installed.  You can specify the eBook filename as the second argument, otherwise `book` will be used.
-  * Generate a **PDF** using:  `gitbook pdf ./myrepo ./mybook.pdf`
-  * Generate a **ePub** using: `gitbook epub ./myrepo ./mybook.epub`
-  * Generate a **MOBI** using: `gitbook mobi ./myrepo ./mybook.mobi`
-* **JSON**: This format is used for debugging or extracting metadata from a book. Generate this format using: ```gitbook build ./myrepo --format=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:
-
-```markdown
-# 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`.
-
-#### 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
-* [English](en/)
-* [French](fr/)
-* [Español](es/)
-```
-
-You can see a complete example with the [Learn Git](https://github.com/GitbookIO/git) book.
-
-#### Glossary
-
-Allows you to specify terms and their respective definitions to be displayed in the glossary. Based on those terms, `gitbook` will automatically build an index and highlight those terms in pages.
-
-The `GLOSSARY.md` format is very simple :
-
-```markdown
-# term
-Definition for this term
-
-# Another term
-With it's definition, this can contain bold text and all other kinds of inline markup ...
-```
-
-#### Variables and Templating
-
-A set of variables can be defined in the `book.json`:
-
-```js
-{
-    "variables": {
-        "host": "mybook.com"
-    }
-}
-```
-
-These variables can be used in the markdown files:
-
-```
-The host is {{ book.host }}
-```
-
-You can also use condition with these variables:
-
-```
-{% if book.host == "mybook.com" %}
-
-{% else %}
-
-{% endif %}
-```
-
-Variables of `book.json` are available in the `book` namespace. You can also access informations about the `file` itself and the `gitbook` version:
-
-```
-My file is {{ file.path }}
-Modified at {{ file.mtime }}
-Book built with GitBook {{ gitbook.version }}
-```
-
-#### Content References
-
-You can use "content references," or conrefs, when writing books or documentation using GitBook.
-
-Include a file from the same book:
-
-```
-{% include "./test.md" %}
-```
-
-or from a git repository (with a specific revision):
-
-```
-{% include "git+https://github.com/GitbookIO/documentation.git/README.md#1.0.1" %}
-```
-
-Includes can be used with variables (see [Variables and Templating](#variables-and-templating)):
-
-```
-{% include book.ref_doc_readme %}
-```
-
-#### 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`).
-
-Best practices for the `.gitignore` is to ignore build files from **node.js** (`node_modules`, ...) and build files from GitBook: `_book`, `*.epub`, `*.mobi` and `*.pdf` ([Download GitBook.gitignore](https://github.com/github/gitignore/blob/master/GitBook.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**.
-
-#### AsciiDoc
-
-Since version 2.0.0, AsciiDoc can be used instead of Markdown, simply replace the `.md` by the `.adoc` extension. Chapters in the summary are detected from an ordered list in the `SUMMARY.adoc`.
+* Write using [Markdown](http://toolchain.gitbook.com/syntax/markdown.html) or [AsciiDoc](http://toolchain.gitbook.com/syntax/asciidoc.html)
+* Output as a website or [ebook (pdf, epub, mobi)](http://toolchain.gitbook.com/ebook.html)
+* [Multi-Languages](http://toolchain.gitbook.com/languages.html)
+* [Lexicon / Glossary](http://toolchain.gitbook.com/lexicon.html)
+* [Cover](http://toolchain.gitbook.com/ebook.html)
+* [Variables and Templating](http://toolchain.gitbook.com/templating/)
+* [Content References](http://toolchain.gitbook.com/templating/conrefs.html)
+* [Plugins](http://toolchain.gitbook.com/plugins/)

-## Plugins
+## Licensing

-Plugins can be 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.
-
-Plugins needed to build a book can be installed using: `gitbook install ./`. You can find plugins at [plugins.gitbook.com](http://plugins.gitbook.com).
-
-
-## 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
-```
-
-#### How to use the latest commit from GitBook in gitbook-cli
-
-To use the latest commit from `GitBook/gitbook` with `gitbook-cli`:
-
-```
-$ git clone https://github.com/GitbookIO/gitbook.git ./gitbook
-$ gitbook versions:link 2.0.0 ./gitbook
-```
-
-Now the version tag `2.0.0` wil be associated with the `./gitbook` folder.
-
-You can uninstall it using: `gitbook versions:uninstall 2.0.0`.

+# 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. |
+| `author` | Name of the author. On GitBook.com this field is pre-filled. |

+
+| 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`).

+# 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).
+
+##### 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 serie 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?
+
+Yes, both the website and ebook outputs can be customized using [themes](themes/README.md).
+
+#### Can I add interactive content (videos, etc)?
+
+GitBook is very [extensible](plugins/README.md). You can use [existing plugins](https://plugins.gitbook.com) or create your own!

+# 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

+# 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 Analytic, 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/lib/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');

+    .then(function() { ... });
+
+// Verify that a file exists
+output.hasFile('hello.txt')
+    .then(function(exists) { ... });

+#### 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": {
+            "myConfigKey": {

+            }
+        }
+    }
+}
+```
+
+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).

+# 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;
+    }
+}
+```

+
+Hooks callbacks can be asynchronous and return promises.

+# 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]

+### LANGS.adoc
+
+For [Multi-Languages](./languages.md) books, this file is used to define the different supported languages and translations.

+# 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
+Text prior to footnote reference.[^2]
+
+[^2]: Comment to include in footnote.
+```
+
+### 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

+# 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.
