+
+## What is Rustup?
+
+Rustup is the official Rust toolchain installer, and makes it easy to keep Rust up to date.
+It supports all Rust platforms, including Windows.
+
+1. `curl https://sh.rustup.rs -sSf | sh`
+2. `rustup install stable`
+
+If that did not work, try:
+
+1. `source ~/.cargo/env`
+2. `rustup install stable`
+
+Or you can use one of the builtin installers:
+
