How can I set up IntelliJ, the community version, for working on an EmberJS project?

How can I set up IntelliJ, the community version, for working on an EmberJS project so I get nice JavaScript ES6 support, handlebars, etc. Is it actually possible?

I did try WebStorm and it was a bit better, but it wasn't fantastic and I'm not sure whether I'll continue to work with EmberJS so I don't want to purchase it yet.
