```
then you need to install the prerequisites, see below:
### Prerequisites
Compiling `steven` requires Rust beta and SDL2. Instructions for setting up SDL2 is platform-specific and will be covered as such outside of this section.
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
```
### Installing dependencies on Linux
Install SDL2 (with headers) via your distro's package manager. Packages with headers generally end with `-dev`.
For example on Debian-based systems such as Ubuntu Linux:
