2. Type in the following commands then hit Enter after each.
sudo add-apt-repository ppa:noobslab/icons
sudo apt-get update
sudo apt-get install flatwoken-icons
FlatWoken icons are divided into two different icon sets: FlatWoken and FlatWokenMin (it is a more minimal reinterpretation of its bigger brother FlatWoken). FlatWoken project is at its early stages. A lot of icons are yet to be designed, and the project is open to external contributors as well as independent single submissions.More at Noobs Lab
