I've been playing around with the theme builder the past few days and have found it very useful. I'm at the point that I want to incorporate my styles into my actually application. Does anyone have any best practices on how to do this? I did read this article, https://blogs.oracle.com/geertjan/integrating-styles-into-oracle-jet-applications, and it mentions to copy the generated.css files to your application. I'm assuming i have to manually rename them to align with my theme name in my actual application. Is that the best way of doing it?

In the theme builder, it has you modify the ....ThemeBuilder\src\themes\mytheme\web\_mytheme.web.settings.scss file. Should I be modifying this file in my actual application?
If anyone else has any best practices, tips or tricks when using the theme builder, that would be very much appreciated as well.
