- Using a Mac and have homebrew? just run `brew tap osx-cross/avr && brew install avr-libc`
4. Copy `keyboard/ergodox_ez/keymaps/default/keymap.c` into `keymaps/your_name/keymap.c` (for example, `keymaps/german/keymap.c`)
5. Edit this file, changing keycodes to your liking (see "Finding the keycodes you need" below). Try to edit the comments as well, so the "text graphics" represent your layout correctly. See below for more tips on sharing your work.

+# ErgoDox EZ Utilities
+
+The Python script in this directory, by [mbarkhau](https://github.com/mbarkhau) allows you to write out a basic ErgoDox EZ keymap using Markdown notation, and then transpile it to C, which you can then compile. It's experimental, but if you're not comfortable using C, it's a nice option.
