WordPress is web software you can use to create a beautiful website or blog. We like to say that WordPress is both free and priceless at the same time.
The core software is built by hundreds of community volunteers, and when you???re ready for more there are thousands of plugins and themes available to transform your site into almost anything you can imagine. Over 60 million people have chosen WordPress to power the place on the web they call ???home??? — we???d love you to join the family.
WordPress started as just a blogging system, but has evolved to be used as full content management system and so much more through the thousands of plugins, widgets, and themes, WordPress is limited only by your imagination. (And tech chops.)
