+[microbit-v2-samples](https://github.com/lancaster-university/microbit-v2-samples)
+
+Once you have verified your build toolchain works by building the `microbit-v2-samples` example,
+you can build the firmware as follows:
+
+	cd microbit-firmata
+	git submodule update --init
+	cd firmware
+	python buildv2.py
+
+The compiled firmware will be at:

+You can use the test suite to confirm that it works.
