📝 Add instructions to install for ember

Added some instructions to install this package and use it in an EmberCLI app.

I came across other unmaintained shims to do this, but they seemed unnecessary. I think updating the docs here will help people who are looking for framework-specific solutions.

If there is a better place for these docs please let me know and I'll move them there.
