If you enter the URL http://localhost/novius-os, the Novius OS installation wizard will appear. Follow the directions; it will first check whether your server configuration is compatible with Novius OS, secondly ask for your database configuration (you will need to first create a database), then ask for some information to create the first user account (necessary to connect to the Novius OS' back office), and finally, ask you which languages you want your website to be available in.

You can now click on Go to the back-office and sign-in.
