Sketch files linked to Sketch libraries

I haven’t used Lunacy yet, but it looks mighty interesting, so I want to try it out.

As my base project, I want to use a Sketch file that has symbols and colour variables in two libraries.

So how do I go about this, but maintain the links to the libraries in the main file?

Sure, you can do that! UI Kits get connected to the whole app, not to a single file.
