### Change the variables below to personalise your site

$site_name = $settings->site_name; # e.g. Steve's Site
$site_root = $settings->site_root; # the folder in which you install puppyCMS. If its at the root of a domain, then simply put '/'. For any other folder, please use trailing slash.

// Get site's url
$site_url = 'http' . (isset($_SERVER['HTTPS']) ? 's' : '') . '://' . $_SERVER['HTTP_HOST'] . '/' . $site_root; // Takes URL but add 'localhost' as subpage

$site_template = 'themes/' . $settings->site_template; #option of puppy.tpl or bootstrap.tpl - in future versions, it can be changed per page

# email for forms - this is the email your enquiries will go to.
$form_email = $settings->from_email;

$link_text = [
	'PuppyCMS' => 'http://puppycms.com',
