<p><em>rustup</em> installs <a href="https://www.rust-lang.org">The Rust Programming Language</a> from the official
release channels, enabling you to easily switch between stable, beta, and
nightly compilers and keep them updated. It makes cross-compiling simpler with
binary builds of the standard library for common platforms. And it runs on all
platforms Rust supports.</p>
<p>Check out the <a href="concepts/index.html">Concepts</a> chapter for an overview of how rustup works and some
of the terminology it uses. The <a href="installation/index.html">Installation</a> chapter covers installing
rustup and getting started.</p>
