# Installing Rust
The first step to using Rust is to install it! There are a number of ways to
install Rust, but the easiest is to use the the `rustup` script. If you're on

in the `$`s, they just indicate the start of each command):

This actually leads to one other concern we should address: this tutorial will
assume that you have basic familiarity with the command-line. Rust does not
assume that you have basic familiarity with the command line. Rust does not
require that you know a whole ton about the command line, but until the
language is in a more finished state, IDE support is spotty. Rust makes no
specific demands on your editing tooling, or where your code lives.

We don't want to take the inverse of zero, so we check to make sure that we
weren't passed one. If we weren't, then we return an `Err`, with a message. If
weren't passed zero. If we were, then we return an `Err`, with a message. If
it's okay, we return an `Ok`, with the answer.
Why does this matter? Well, remember how `match` does exhaustive matches?
