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.
The documentation can be accessed directly via the WooThemes website. It can also be accessed from your WordPress site. Follow these steps to find the documentation:
In the WordPress admin, click on the Plugins menu to see the list of installed plugins.
Click on the Docs link under WooCommerce, as shown in the following screenshot, which will take you to the documentation on http://www.woothemes.com:
Now that you're in the documentation section, navigate to the section you need. Getting Started is great for someone just starting their store, Codex is great for people who want to customize WooCommerce or their theme, and Extensions is great for any WooCommerce extensions you may have.
