How to add new libraries?

[camposfyi]

How do I go about adding an external library? For instance I'm trying to add this library: https://github.com/skeymeulen/swangular

I've seen example using bower to manage dependencies. However, the way this project is set up, I don't see a way to easy add a new external dependency.

How would you go about doing this?
