Websites can be a pain to set up--even with HTML and CSS, hand-coding a site can take hundreds of hours. And it gets worse if you want a website you can update frequently because you’d have to dig back into the original code to make changes. Enter the CMS, or content-management system, designed to let you easily update a site without monkeying with the underlying code. WordPress is perhaps the most impressive, powerful, and widely used blogging CMS there is. For beginners and non-technical types, it’s incredibly easy to set up, even if you’re using your own domain. More advanced users can tweak WordPress to an incredible degree with themes and plug-ins, and power users can even adjust the open-source code with a basic text editor.
