Finding documentation on WooThemes.com

WooCommerce has been developed by WooThemes, a WordPress theme and plugin development shop. In addition to developing the plugin, they've also created hundreds of pages of documentation for WooCommerce and all of the extensions.

If you want to dig into exactly what settings are available and how they interact with other settings, you should know how to find the documentation in the first place. Some people like to read through the documentation ahead of time and others like to explore the settings without reading the documentation and only refer to it if they are stuck. Either way works.
