FWIW, a lot of people tell us Redux's docs are "great", but we've also had people tell us they aren't helpful. Kinda hard to figure out how to make improvements based on that kind of conflicting feedback :)
We are actually looking at revamping the Redux docs in the near future [0]. If you've got any specific concerns or suggestions on how we can improve things, please let me know directly, or comment on that issue.
Also, besides the docs, you may be interested in my suggested resources for learning Redux [1], including my own Redux workshop slides [2].
