This is a tutorial about KDEPlasmaAntDarkStyle including an install.sh

Forgive me that I can't describe all things exactly with just words. You can watch the tutorial video by LinuxScoop

Tips: Some settings have been deprecated or changed due to version changes, and you don't need to stick to the book.
