Here are step to create the Magento2 Extension

create registration.php

<?php
/**

* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'QaisarSatti_HelloWorld',
__DIR__
);

Create module.xml

app/code/QaisarSatti/HelloWorld/etc/module.xml

<?xml version="1.0"?>
<!--/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/ -->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="QaisarSatti_HelloWorld" schema_version="0.0.1" setup_version="0.0.1"/>
</config>

Create block

* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
namespace QaisarSatti\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
public function _prepareLayout()
{
parent::_prepareLayout();
$this->pageConfig->getTitle()->set(__('First Hello World Module'));
return $this;
}
}

* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
namespace QaisarSatti\HelloWorld\Controller\Index;
class Index extends \Magento\Framework\App\Action\Action
{
public function execute()
{
$this->_view->loadLayout();
$this->_view->renderLayout();
}
}

<?xml version="1.0"?>
<!--/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/ -->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="helloworld" frontName="helloworld">

</route>
</router>

* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
echo 'Hello World';
?>

<?xml version="1.0"?>
<!--/**

*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/ -->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
