+Pick a directory to work in, you'll need to clone multiple repositories. We'll assume you picked `$HOME/keyboardio`, if you chose another adapt the commands below accordingly.
-depend on. To do that:
 
+## Setup the Arduino IDE
+
+Setup the Arduino IDE on your system. Make sure you install at least version 1.6, since older version may not support all required features.
+
+* On Linux, follow the instructions [on the wiki](https://github.com/keyboardio/KeyboardioFirmware/wiki/Arduino-Setup-Linux).
+* On macOS, install using [homebrew](http://brew.sh/) [cask](https://caskroom.github.io/) with `brew cask install arduino` or download the application from [the official website](https://www.arduino.cc/en/Main/Software) and move it to your `/Applications` folder.

+## Install the Keyboardio Hardware Definitions
+
+```sh
+# you'll need to know your arduino sketchbook directory
+
+# on macOS the default is
+SKETCHBOOK_DIR=$HOME/Documents/Arduino
+# on Linux the default is
+SKETCHBOOK_DIR=$HOME/Arduino
+
+# go to your keyboardio directory
+cd $HOME/keyboardio
+# then clone the hardware definitions
+git clone --recursive https://github.com/keyboardio/Arduino-Boards.git
+# and make them available to the arduino environment
+mkdir -p $SKETCHBOOK_DIR/hardware/keyboardio
+ln -s $HOME/keyboardio/Arduino-Boards $SKETCHBOOK_DIR/hardware/keyboardio/avr
 ```
-$ cd KeyboardioFirmware
+
-$ git submodule sync --recursive
+## Clone and Build the Keyboardio Firmware
-$ git submodule update --init --recursive
+
-$ cd source
+```sh
-$ make
+# go to your keyboardio directory
+cd $HOME/keyboardio
+# then clone the firmware repository
+git clone https://github.com/keyboardio/KeyboardioFirmware.git
+# and build your firmware!
+cd KeyboardioFirmware
