Git - What is subtree?

I had a problem with git recently. I was developing a plugin for the Atom text editor. I am developing in ClojureScript (Check this out if you want a preview of what this is) that is compiled to JavaScript. I then faced the (sad?) reality of Atom releases. The plugin must be at the root of the git repository on the master branch.

This is not going to work out for me as my file setup is like this:

.                     # This is the root of my git repo
├── assets
├── plugin            # This is where my plugin is compiled
├── project.clj
├── src               # This is my ClojureScript source
└── target

I was facing a problem: I want the content of my plugin folder to be pushed on a master branch.
