 * Best to be used with Amazon Cloudfront as SSL terminator and CDN
 * Built on the lightweight Alpine Linux distribution
 * Small Docker image size (+/-50MB)
-* Uses PHP 7.4 for better performance, lower cpu usage & memory footprint
+* Uses PHP 8.0 for better performance, lower cpu usage & memory footprint
 * Can safely be updated without losing data
