It is the most popular CMS in the world, powering over 43% of all websites on the internet. WordPress can be used to create a variety of websites, including hobby or lifestyle blogs, professional portfolios, business websites, e-commerce stores, mobile applications, and membership sites. Some of the key features of WordPress include:

• Flexibility: WordPress is highly customizable, with a plugin architecture and a template system that allows users to customize any website to fit their needs.

WordPress can be used in two ways: through WordPress.org, which requires users to host their own website or blog and manage their own server, or through WordPress.com, which is an all-in-one option that has most of the hard work done for users. Overall, WordPress is a versatile and powerful tool that can be used by beginners and experienced web developers alike to create professional-looking websites quickly and easily.
