To install the Chrome/Chromium theme go to the extra/Chrome folder and drag and drop the arc-theme.crx into the Chrome/Chromium window. The source of the Chrome themes is located in the source "Chrome/arc-theme" folder.

To install the Plank theme, copy the extra/Arc-Plank folder to ~/.local/share/plank/themes or to /usr/share/plank/themes for system-wide use. Now open the Plank preferences window by executing plank --preferences from a terminal and select Arc-Plank as the theme.
