sudo pacman -S cinnamon-translations
We have a vanilla Arch installation and we keep installing elements like :
- icon theme
- text editor
- conky and Aureola conky
- ArcoLinux wallpapers
- plank and ArcoLinux themes
This time we do NOT run the scripts from https://github.com/arcolinuxd/arco-cinnamon.
You will have to figure things out yourself with the wiki from Arch Linux, Youtube and ofcourse ArcoLinux and ArcoLinuxD.
