GENERAL SUPPORT QUESTIONS ARE OFF-TOPIC. Arch Linux is a Linux distribution intended to be lightweight and simple. Its development is focused on simplicity, elegance, code correctness and minimalism from a developer's standpoint.
Arch Linux is an independently developed, i686/x86-64 general purpose GNU/Linux distribution versatile enough to suit any role. Development focuses on simplicity, minimalism, and code elegance. Arch is installed as a minimal base system, configured by the user upon which their own ideal environment is assembled by installing only what is required or desired for their unique purposes. GUI configuration utilities are not officially provided, and most system configuration is performed from the shell and a text editor. Based on a rolling-release model, Arch strives to stay bleeding edge, and typically offers the latest stable versions of most software.
The early years
Judd Vinet, a Canadian programmer and occasional guitarist, began developing Arch Linux in early 2001. Its first formal release, Arch Linux 0.1, was on March 11, 2002. Inspired by the elegant simplicity of slackware, Polish Linux Distribution, and CRUX, and yet disappointed with their lack of package management at the time; Vinet built his own distribution on similar principles as those distros. But, he also wrote a package management program called pacman, to automatically handle package installation, removal, and upgrades.
The middle years
The early Arch community grew steadily, as evidenced by this chart of forum posts, users, and bug reports. Moreover, it was from its early days known as an open, friendly, and helpful community.
The dawning of the age of A. Griffin
In late 2007, Judd Vinet retired from active participation as an Arch developer, and smoothly transferred the reins over to American programmer Aaron Griffin, aka Phrakture, who remains the lead Arch developer to this day. Over the years, the Arch community continued to grow and mature, and has recently received an unusual amount of attention and review for a Linux distro of its modest size. Arch developers remain unpaid, part-time volunteers, and there are no prospects for monetizing Arch Linux, so it will remain free in all senses of the word. Those curious to peruse more detail about Arch's development history can browse the Arch entry in the Internet Archive Wayback Machine.
The Arch Way
The following five core principles comprise what is commonly referred to as the Arch Way, or the Arch Philosophy, perhaps best summarized by the acronym KISS for Keep It Simple, Stupid.
Simplicity
Arch Linux defines simplicity as without unnecessary additions, modifications, or complications, and provides a lightweight UNIX-like base structure that allows an individual user to shape the system according to their own needs. In short: an elegant, minimalist approach.
Code-correctness over convenience
Simplicity of implementation, code-elegance, and minimalism shall always remain the reigning priorities of Arch development.
User-centric (Not to be mistaken with user-friendly)
Arch Linux targets and accommodates competent GNU/Linux users by giving them complete control and responsibility over the system.
Openness
Arch Linux uses simple tools, that are selected or built with openness of the sources and their output in mind.
Freedom
By keeping the system simple, Arch Linux provides the freedom to make any choice about the system.
