 ## Usage
 
-Games are loaded from your iPhone's documents directory. In iTunes, drop `.gb`, `.gbc`, or `zip` files into the Giovanni app documents folder, and they'll show up automatically on your Apple Watch. When you play a game for the first time, it'll download to your watch and get cached in the watch's documents directory. Subsequent loads are immediate.

 UPDATE: Giovanni can open ROMs natively, allowing you to bypass iTunes entirely. [More info](https://github.com/gabrieloc/GIOVANNI/pull/9).
