# Build Guide ## Build Environment Setup ### Windows What these instructions look like depends on whether NoahAndrews's setup scripts get merged ### Mac If you're using homebrew, you can use the following commands: brew tap osx-cross/avr brew install avr-libc brew install dfu-programmer Otherwise, these instructions will work: 1. Install Xcode from the App Store. 2. Install the Command Line Tools from `Xcode->Preferences->Downloads`. 3. Install [DFU-Programmer][dfu-prog]. ### Linux ### Vagrant If you have any problems building the firmware, you can try using a tool called Vagrant. It will set up a virtual computer with a known configuration that's ready-to-go for firmware building. OLKB does NOT host the files for this virtual computer. Details on how to set up Vagrant are in the [VAGRANT_GUIDE file](VAGRANT_GUIDE.md).
