If you download the zip be sure to pull the directory ro_panel_styles out of the ro_panel_styles-master zip file and ro_panel_styles-master dir.
- BAD: ro_panel_styles-master
- GOOD: ro_panel_styles
The file named ro_panel_styles.info should be placed in a directory structure like sites/all/modules/ro_panel_styles/ro_panel_styles.info

First we start with our own module. In this scenario I created a module called example styles.
- example_styles.info
- example_styles.module
- plugins/styles/example/example.inc
- plugins/styles/example/example-pane.tpl.php
- plugins/styles/example/example.css
- plugins/styles/example/example-region.tpl.php
