Create a basic front-office Controller Prestashop 1.7 - prestashop

Question

I am a beginner and I am learning how to create a front-office controller. I have written the following code but shows nothing when I load the page. I haven't given any reference to it in my module code yet. How should I proceed?
<?php
if (!defined('_PS_VERSION_')) {
exit;
}
class AbcMyPageModuleFrontController extends ModuleFrontController
{
public function initContent()
{
parent::initContent();
$this->setTemplate('module:abc/views/templates/front/myFirst.tpl');
}
}

Your path to your file seems wrong, here is a simple version for your eyes only :
<?php
// Edit name and class according to your files, keep camelcase for class name.
require_once _PS_MODULE_DIR_.'modulename/modulename.php';
class ModuleNameAjaxModuleFrontController extends ModuleFrontController
{
public function initContent()
{
$module = new ModuleName;
// Usefull vars derivated from getContext
$context = Context::getContext();
$cart = $context->cart;
$cookie = $context->cookie;
$customer = $context->customer;
$id_lang = $cookie->id_lang;
// Template path : modules/modulename/views/template/front/template.tpl
// Just put some vars in your template
$this->context->smarty->assign(array('myvar'=>'thevalue'));
$this->setTemplate('template.tpl');
}
}
