You'll need WordPress installed on your server in order to be able to use Brizy's power and start creating your website. Brizy for WordPress is a plugin so it needs WordPress to work.
If you need hosting for your website try one of our hosting partners here: https://www.brizy.io/hosting-partners/
You'll get WordPress installed by default, we've tested Brizy and it works perfectly with all of them, plus, if you'll get any hosting plan through our links, you'll get 1 year of Brizy PRO for FREE.
If you already have hosting and want to install WordPress yourself, there are literally hundreds if not thousands of tutorials out there on how to do it so here is a video from our friend Adam from WPCrafter where he explains it step by step.
You'll be able to follow even if you are doing it for the first time.
