-### Prerequisites
-
-An easy way to manage multiple Rust toolchains is [`rustup`](https://github.com/rust-lang-nursery/rustup.rs). Installation instructions for `rustup` can be found on its [website](https://www.rustup.rs/).
-
-Once you've set up `rustup`, grab Rust beta by running
-```sh
-rustup install beta
-```
-
-Now we need to make sure that `steven` is compiled with beta. To do this without making beta the default across the entire system, run the following command in the `steven` directory:
-```sh
-rustup override set beta
-```
