As someone who was almost immediately made happy by React, ES6, Redux, and boilerplates, I'm not the target audience. But I feel like this would make me un-sad if I felt overwhelmed by all the choices.

I think the Redux guide itself (http://redux.js.org/) also does a fantastic job of a very gradual release into complexity. I recommend that anyone who feels they may want a Flux-like store read through the whole guide. It took me a day or two, but I found it to be extremely clear and enlightening.
