+# Adafruit Gemma M0 Board Support Crate
+
+This crate provides a type-safe API for working with the [Adafruit Gemma M0
+board](https://www.adafruit.com/product/3501).
+
+## Prerequisites
+* Install the cross compile toolchain `rustup target add thumbv6m-none-eabi`
+* 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/gemma_m0/examples
+
+* Be in this directory `cd boards/gemma_m0`
+* Put your device in bootloader mode usually by hitting the reset button twice.
+* Build and upload in one step
+```
