1. `cd` into `examples/hello-world/`
2. Run `cargo run hello.roc` to compile the Roc source code into a `hello.o` file.
3. Run `gcc -shared hello.o -o libhello_from_roc.so` to generate `libhello_from_roc.so`. (This filename must begin with `lib` and end in `.so` or else `host.rs` won't be able to find it!)
4. Move `libhello_from_roc.so` onto the system library path, e.g. with `sudo mv libhello_from_roc.so /usr/local/lib/`
4. Move `libhello_from_roc.so` onto the system library path, e.g. with `sudo mv libhello_from_roc.so /usr/local/lib/` on macOS, or `sudo mv libhello_from_roc.so /usr/local/lib /usr/lib` on Linux.
5. Run `rustc host.rs -o hello` to generate the `hello` executable.
6. Run `./hello` to see the greeting!
