 `intel_fw` is written from scratch in Rust, allowing for integration with other
 projects, including a programmatic API.
 
+## Development
+
+To run the CLI via `cargo` directly, remember to add arguments after an extra
+`--`; i.e., to print the general help, invoke `cargo run --relase -- -h`, or,
+for a subcommand, e.g. `cargo run --relase -- me clean -h`.
+
+This tool uses the [`clap` command line argument parser in _derive_ mode](https://docs.rs/clap/latest/clap/_derive/index.html).
+To familiarize yourself with Rust and common approaches to CLI tools, take a
+look at the [Rust CLI book](https://rust-cli.github.io/book/index.html).
