Arch Linux is a Linux distribution for computers with x86-64 processors. The Arch Linux repositories contain both libre, and nonfree software, and the default Arch Linux kernel contains nonfree proprietary blobs, hence the distribution is not endorsed by the GNU project.
Arch Linux adheres to five principles: simplicity, modernity, pragmatism, user centrality and versatility. In general, the principles maintain minimal distribution-specific changes, minimal breakage with updates, pragmatic over ideological design choices, user-friendliness, and minimal bloat.
