Please add build and run instructions to the doc :)

Hi! The docs don't seem to include the build and run instructions:

cargo build --release
cargo run --release

I'm familiar enough with software that I figured it out, but would be helpful for anyone who doesn't already know Rust. Thank you :)

There's a bit more to it as well as you may need to install dependencies on different platforms.

Just fyi, cargo run will also build the project first.

I've started a Wiki page with build instructions. I'll flesh this out a bit more. I can't remember all the dependencies I had to install on Ubuntu but I'll reinstall a fresh VM and document everything I had to do. If anyone wants to contribute instructions for other repos that would be helpful.
