 2. Install required packages
 
 ATTENTION: Installing the CachyOS Pacman, will install a forked pacman with features added from CachyOS, like "INSTALLED_FROM" and an automatic architecture check.
-Pacman 6.1 added a feature validation feature, which could lead when using the Archlinux pacman into warnings. We are working with archlinux to provide a proper compatibility again.
+Pacman 6.1 added a feature validation feature, which could lead when using the Arch Linux pacman into warnings. We are working with Arch Linux to provide a proper compatibility again.
 If you want to avoid this, don't add the "cachyos" repository, which contains the customized pacman. All other repositories like cachyos-v3, cachyos-v4, cachyos-extra/core-v3/4 are fine to add.
 
 ```

+sudo find /var/lib/pacman/local/ -type f -name "desc" -exec sed -i '/^%INSTALLED_DB%$/,+2d' {} \;
