How can I set up projects that use all the same scripts but different resources?

I have a common script set that I use for two different Unity projects. I just have different resource folders.

What is the best way to setup up the projects so I do not have duplicate script folders?

I want to be able to modify the scripts from either project and have it updated also in the other project.

 

I think I found my solution
