 ## 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**.
-* **JSON**: This format is used for debugging or extracting metadata from a book. Generate this format using: ```gitbook build ./myrepo -f json```.
+* **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```.

+
+```js
+{
+    "variables": {

+    }

+```
+
+These variables can be used in the markdown files:

+
+{% 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 }}

+#### Content References

+You can use "content references," or conrefs, when writing books or documentation using GitBook.

-# Learn Node.js by Example
-
-
-## Requirements
-
-- [x] A computer with internet access
-- [ ] Time: 30h (e.g. 2 months 30 mins per day or **1 week intensive**)
-
-
-## What is Node.js ?
-
-Node.js lets you *easily* build networked software (websites, applications "apps",
-using JavaScript).
-
-Its not "*point-and-click*" like WordPress, SquareSpace or Salesforce;
-you will need to write some "code". But as I will demonstrate, that's
-a *lot* easier than it sounds and gives you more power/flexibility
-and puts you in full control.
-
-## Node.js is not "Version 1.0" yet can I used it in Production?
-
-Yes! Some of the biggest organisations/companies in the world
-are using Node.js in Production systems:
-
-[Alibaba](https://github.com/alibaba/node-hbase-client),
-[Ajax.org](Ajax.org),
-[Box.com](http://tech.blog.box.com/2014/06/node-js-high-availability-at-box/), British Sky Broadcasting (Sky/Now TV),

-
-## Node.js (Core) API
-
-The node.js ("core") has many useful modules.
-
-Bookmark: [http://nodejs.org/api](http://nodejs.org/api/) (you will come back to it)
-
-
-
-## Stability (Can we use it?)
-
-> *Which node.js* ***core*** *package(s) can/should I use?*
-
-Every core module has a
-["***Stability Index***"](http://nodejs.org/api/documentation.html#documentation_stability_index)
-rating on the node.js API.
-
-**General rule**: If you are being *paid* to write code
-that runs in node.js, <br /> pick core modules/methods
-with stability **Stable**, **API Frozen** and **Locked**.
-
-![Node.js Stability Index](http://i.imgur.com/xIroFrS.png)

-- [**domain**](http://nodejs.org/api/domain.html) is ***Unstable*** - don't use
