Magento 2 has established itself as one of the most powerful and flexible e-commerce platforms available today. Now owned by Adobe and marketed as Adobe Commerce, this robust solution powers thousands of online stores worldwide. This comprehensive guide will walk you through everything you need to know about Magento 2, from basic concepts to practical implementation.

What is Magento 2?

Magento 2 is an open-source e-commerce platform that provides merchants with a comprehensive solution for creating and managing online stores. Originally developed by Varien Inc. and later acquired by Adobe, Magento 2 represents a complete rewrite of the original Magento platform, offering improved performance, enhanced security, and a more modern architecture.

The platform comes in several editions:

    __DIR__
);
  1. Create theme.xml:
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
    <title>Your Custom Theme</title>
