 ## Notes
 
-Script has been tested to work with following distros:
+Script supports following Linux distributions and versions:
 
 - CentOS 8 (note LVM file level restore issue from below)
+- AlmaLinux 8
+- Rocky Linux 8
 - Debian 10
-- Ubuntu 20.04
-- AlmaLinux 8 (early testing phase)
-
-Installation works but not tested frequently:
-- Debian 8
 - Debian 9
-- Ubuntu 16.04
+- Debian 8
+- Ubuntu 20.04
 - Ubuntu 18.04
+- Ubuntu 16.04
+
+Note that even though multiple distributions and versions are supported, tests are ran only against newest Debian/Centos/Ubuntu. 
+
+Your distribution not in the list? Set OS_CHECK variable to false in xo-install.cfg to skip operating system version check.
 
 In order to use file level restore from delta backups, the service needs to be ran as root.
-CentOS installation is currently not able to do file level restore if the backed up disk contains LVM or only sees some of the partitions.
 
 CentOS setup is confirmed to work with fresh minimal installation and SELinux enabled.
 Although script doesn't do any SELinux checks or modifications, so you need to take care of possible changes by yourself according to your system.
