WordPress is a content management system (CMS) that is used for creating and managing websites. It is based on PHP and MySQL, and it is designed to be easy to use, even for those who are not web developers.
WordPress is open-source software, which means that it is free to use and modify. It is also highly customizable, with a wide range of themes and plugins that can be used to change the appearance and functionality of a WordPress site.
