+## 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
+```

+# 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.
+
+
+### Publish your plugin

+# 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.

+# Internationalize your plugin

+# 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

+    .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" %}

+# 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

+# 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": {
+                "type": "string",
+                "default": "it's the default value",
+                "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

+
+    // 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;
+    }
+}
+```

+# 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\*.
+```

+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.
