If you don’t understand an option or something does not work as expected read the documentation. It’s installed in /usr/share/doc/bashstyle-ng/index.html ( /usr is default but may vary if you passed an other prefix to configure).
Currently BS-NG shipps 15 pre-defined Styles for your prompt. Most of them can be modified via the Custom Prompt Builder. If you want to save your current configuration and want to re-import it later (or for using it on a different user/machine) you can do so via the Profiler (bs-ng-profiler
Standalone (GConf-Free) Configuration (for faster Bash-Startup) can be created via the RCGenerator (rcgenerator
