+DISCUSSION:
+    Rustup installs The Rust Programming Language 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.
+
+    If you are new to Rust consider running `rustup doc --book` to
+    learn Rust.
