Hey, sorry for the long delay. Thanks for the suggestion!

I’m not opposed to adding exemplary build instructions, but what to do depends on the system, so it should be clear in every step that it’s an example.

1. install rust: `curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh`

How to install Rust best depends entirely on the needs and wants of the user; some (most?) prefer rustup, some prefer tracking rustc and cargo through their package manager. Personally, I’m not a fan of suggesting to run some shellscript off the internet without verifying its contents first. (I’ve always installed rustup through my package manager.) We can certainly point to rustup, and point to https://rustup.rs for installation options, then the way they recommend is at least off of our hands. (E.g. “install rust, e.g. through rustup (see https://rustup.rs for installation options)”.)

3. install needed packages: `sudo apt-get install libusb-1.0-0-dev pkg-config`

How to install these packages again depends on the system. I, for example, don’t have any that uses APT. We can certainly point out that building requires the libusb1 devel package (“package name depends on your system, e.g. ‘libusb-1.0-0-dev’ or ‘libusb1-devel’”) and pkg-config.

As for building/installing, well, it’s cargo. What I usually do is just cargo build --release and then grab the binary from target/release.

I've never used Rust before, so it took me a while to figure out how to run your tool. That's why I thought that some kind of guidance would be great for other Rust noobs like me. But, yeah, you're right. The steps depend heavily on the system used. :)
