 Currently, PHP, Composer, and Redis are installed from Remi's modular repository. As such, they will only get minor version updates with `dnf upgrade` (PHP 8.1.0 -> PHP 8.1.x for example). For updates between major versions of these dependencies, use `dnf module` to change the appstream for these dependencies.<br />
 
 ```bash
-dnf module reset php:remi-8.0
-dnf module install php:remi-8.1
-dnf distro-sync
+dnf module switch-to php:remi-8.1

 NGINX, MariaDB, and Docker-CE uses upstream repositories and will get the latest version available on there automatically.

 # Supported Distributions
 Only RHEL 9 and its derivatives (CentOS Stream 9, Rocky Linux 9 , AlmaLinux 9) are supported at the moment. Fedora may get supported in the future if there are interest in it.
 
-Ubuntu, Debian, and openSUSE are unlikely to get supported, due to them not supporting modular repositories which makes dependency updates cumbersome.
