Installing plasma requires only a few lines. Theming and tweaking your Arch Linux system will require more time. All the information about this desktop is here:
sudo pacman -S plasma-meta
Now we will install all the Kde applications. If you install them one by one, you can now see what is in the package of plasma and what is in the next package.
sudo pacman -S kde-applications-meta
Your installation can just end here. Then you add more applications to have a system suited to your needs and theme it anyway you like.

We will use the ArcoLinuxD github to get our system quickly up and running.
git clone https://github.com/arcolinuxd/arco-plasma

And improve our scripts by adding software or deleting software.
