+# Ergodox EZ for OS X
+
+This keymapping is designed to be reasonably familiar to an ordinary Mac keyboard while taking advantage of the Ergodox EZ's features. Caps lock instead enables a layer which allows a user to use HJKL as arrow keys and to control media. Shift and control have additional mappings on S and D to provide easier access while holding down caps lock. 
+
+If you choose to compile this yourself, be sure to compile with `#define PREVENT_STUCK_MODIFIERS` in your `config.h`. Firmware built using [qmk_firmware](https://github.com/jackhumbert/qmk_firmware/).
