Overview of WordPress
WordPress is a free and open source content management system (CMS) based on PHP and MySQL. It is the most widely used CMS software in the world, and as of May 2019, it powers more than 30% of the top 10 million websites and has an estimated 60% market share of all websites built using a CMS.
WordPress started as a simple blogging system in 2003, but it has evolved into a full CMS with thousands of plugins, widgets, and themes. It is licensed under the General Public License (GPLv2 or later).
