-## Build Instructions
-1. Install prerequisites as described in the [`avr-hal` README] (`avr-gcc`, `avr-libc`, `avrdude`, [`ravedude`]).
-
-2. Run `cargo build` to build the firmware.
-
-3. Run `cargo run` to flash the firmware to a connected board.  If `ravedude`
-   fails to detect your board, check its documentation at
-   <https://crates.io/crates/ravedude>.
-
-4. `ravedude` will open a console session after flashing where you can interact
-   with the UART console of your board.
