You can follow our tutorials based on either of two iso's.
1. ArcoLinuxB Plasma (recommended)
We record the plasma video's on an SSD installed from the ArcoLinuxB Plasma iso.
You can either create your very own ArcoLinuxB Plasma iso following this tutorial or download it from Sourceforge. (ArcoLinuxB-plasma-18.11.2.iso of 4.3 GB - games included)
2. ArcoLinuxD Plasma
You can also use the ArcoLinuxD iso and then install Plasma with the help of the github scripts. This will not be an exact copy of the iso.
Learn about the Plasma desktop and enjoy it.
