Nice ![]()
Since you mentioned that you already have ruby files, I’m guessing that you’re working on a plugin, right?
So, to answer your question
I would recommend that you look at the folder structure of some of our existing official plugins like this one
https://github.com/discourse/discourse-math
or this one
https://github.com/discourse/discourse-assign
If you look at those, you’ll notice that the SCSS stylesheets are always placed in
_ROOT_/assets/stylesheets/
and that’s where your SCSS files should go if you’re making a plugin.
