Primarily you must upload ReloadCMS distribution to your host.

If your host is based on UNIX-Like OS you must recursively set rights 0777 for directories ‘backups’, ‘config’ and ‘content’. You can test rights by running ./tools/rights_test.php from ReloadCMS distribution.

Then you must register your first user (that will be Root administrator of your site) and log in with selected username and password. Now you can go to Administration and configure your site.
