How to install the Material skin on FM20
Extract the contents of the .rar archive using a tool such as WinZip or 7-zip.

Move the extracted folder "Material skin" to:
\Documents\Sports Interactive\Football Manager 2020\skins
Create folder "skins" if it doesn't exist already.

Start the game and go to Preferences screen, and then to the Interface tab.
You should see "Material Skin" as options in the skin drop down of the Overview box.
Use the Clear Cache button, then hit the Confirm button.
