 You should always use `.md` extensions for your relative links, GitBook will automatically replace these links by the right value 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. GitBook.com and the CLI also looks by default in a series of [folders](structure.md).

+# 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's best and easier solution for publishing your content and collaborate on it.
+
+It integrates well with the [GitBook Editor](https://www.gitbook.com/editor).
+
+### Local Installation
+
+##### Requirements
+
+Installing GitBook is easy and straight-forward, but there are a few requirements you’ll need to make sure your system has before you start.
+
+* NodeJS (v4.0.0 and above are adviced)
+* 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 to build a book.
+
+##### Using pre-releases
+
+`gitbook-cli` makes it easy to install and test other versions of GitBook with your book:
+
+```
+$ gitbook install beta
+```
