ArcoLinux is a distribution based on Arch Linux. The development takes places in three branches - ArcoLinux, ArcoLinuxD and ArcoLinuxB. ArcoLinux is a full-featured distribution that ships with the Xfce desktop (as well as Openbox and i3 window managers). ArcoLinuxD is a minimal distribution that includes scripts that enable power users to install any desktop and application. ArcoLinuxB is a project that gives users the power to build custom distributions, while also developing several community editions with pre-configured desktops, such as Awesome, Bspwm, Budgie, Cinnamon,Cwm, Deepin, Dwm, Enlightenment, Gnome,Herbstluftwm, i3, Jwm, Lxqt, Mate, Openbox, Plasma, Qtile, Spectrwm, Sway, Xfce and Xmonad. ArcoLinux also provides various video tutorials as it places strong focus on learning and acquiring Linux skills.
