Manjaro is a user-friendly GNU/Linux distribution based on the independently developed Arch Linux.
Manjaro Linux is based on Arch Linux and has its own collection of repositories. The distribution aims to be new user-friendly while maintaining the Arch base, most notably the Pacman package manager and compatibility with the Arch User Repositories. Manjaro itself uses three sets of repositories: the unstable repositories contain the most bleeding edge Arch packages, possibly one or two days delayed; the testing repositories contain packages from the unstable repos synced every week, which provides an initial screening; and the stable repositories contain only packages that are deemed stable by the development team.
