+##Introduction
+
+This guide is for developers that need to modify or customize an existing Magento module, or are building a new module from scratch either for custom extension of Magento functionality. This guide is also for those who want to create an extension for Magento Connect, although it does not cover the publishing process.
+
+
+##Magento is made up of components:
+
+* Modules
+* Libraries
+* Themes
+* Language packages
+
+
+A Magento **module** is a discrete chunk of code that accomplishes a particular business function or handles a Magento feature. They are typically a collection .php and .xml files, and the bulk of your work in modules will be in these files.  Modules are interactive with each other. A module also contains the user interface required for a user’s interaction with the module. Themes can be applied to the module to change its appearance. So when you are building a module, you may also touch themes and language packs.
+
+A **package** is a module that is wrapped up in a distributable form. Usually you will use Composer to do this. This can be released on 
+
+An **extension** is a module that is packaged for sale on Connect.

+<p>You must follow a PSR compliant structure when building a module.</p>
+</div>
+
+
+##Magento module example
+
+At the very minimum, a Magento module could simply be an XML file:
+
+    <?xml version="1.0"?>
+    <!--
+    /**
+    * @copyright Copyright (c) 2015 X.commerce, Inc. (http://www.magentocommerce.com)
+    */
+    -->
+    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
+      <module name="Magento_SampleMinimal" setup_version="2.0.0">
+      </module>
+    </config>
+
+
+##What's Next?
