+# Adafruit Matrix Portal M4 Board Support Crate
+
+This crate provides a type-safe API for working with the [Adafruit Matrix Portal M4
+board](https://www.adafruit.com/product/4745).
+
+## Prerequisites
+* Install the cross compile toolchain `rustup target add thumbv7em-none-eabihf`
+* Install [cargo-hf2 the hf2 bootloader flasher tool](https://crates.io/crates/cargo-hf2) however your platform requires
+
+## Uploading an example
+Check out the repository for examples:
+
+https://github.com/atsamd-rs/atsamd/tree/master/boards/matrix_portal_m4/examples
+
+* Be in this directory `cd boards/matrix_portal_m4`
+* Put your device in bootloader mode usually by hitting the reset button twice.
+* Build and upload in one step
+```
+
+$ cargo hf2 --release --example blinky_basic --vid 0x239a --pid 0x00c9
+    Finished release [optimized] target(s) in 0.74s
+    Trying  Ok(Some("Adafruit Industries")) Ok(Some("Matrix Portal M4"))
+    Flashing "/Users/User/atsamd/boards/matrix_portal_m4/target/thumbv7em-none-eabihf/release/examples/blinky_basic"
