Nex1on installs from an ordinary archive: unpack it on your hosting, open the site address in a browser, and the installer asks for the database details and creates the first administrator. No SSH and no Composer needed.
What you need #
Hosting with PHP 8.2 or newer and a MySQL or MariaDB database. Nothing else: no build step, no command line.
Three installer steps #
First the installer checks the server and shows what is missing. Then it asks for the database details, and at the end it creates the first administrator. From that moment the site works, and everything else is set up in the control panel.
Site root and security #
It is best to point the site root at the public folder: then the engine code sits one level above and cannot be reached from the browser. If the root cannot be changed, the bundled .htaccess file closes off everything else.
What next #
Turn on the modules you need, pick a theme and build the home page right in the panel. Engine updates are also installed from the panel, and next to the update button there is a button to make a backup of the files and the database.
