Install error - custom theme

Permalink
I am installing concrete5.6.3.3 and have this error come up-

File /var/www/vhosts/domainname.co.nz/httpdocs/concrete5.6.3.3/concrete/themes/HAYES/default.php not found. All themes need default.php and view.php files in them. Consult concrete5 documentation on how to create these files.

How can I resolve this?
thanks
