Magento 2 - Display/Show Custom module on homepage - magento

Question

I am in new Magento 2 and have created a custom module, its working fine with the url(http:///modulename/index/test) but need to call it on home page. I mean when home page loaded, module would be called automatically. How it possible?
Below is the steps which I followed during module creation -
Step 1: Created the Namespace and module folder
Step 2: Created etc/module.xml file
<?xml version="1.0"?><config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Ignvia_HelloWorld" setup_version="1.0.0">
</module>
Step 3: Created etc/registration.php file
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Ignvia_HelloWorld',
DIR
);
Step 4: Created etc/frontend/routes.xml file
<?xml version="1.0" ?><config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route frontName="helloworld" id="helloworld">
<module name="Igniva_HelloWorld"/>
</route>
</router>
Step 5: Created Controller/Index/Test.php
<?php
namespace Igniva\HelloWorld\Controller\Index;
class Test extends \Magento\Framework\App\Action\Action
{
protected $_pageFactory;
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $pageFactory)
{
$this->_pageFactory = $pageFactory;
return parent::__construct($context);
}
public function execute()
{
echo "Hello World";
exit;
}
}
Thanks.

To load your custom module in homepage, your code should be called in cms_index_index layout(not in core file).you have to define in custom file.
