Documentation improvement

This really should be in the master Readme... it took me way to long to find it :) Such a simple solution too. I'm using it to generate data releases for offline clients in a background task.

@criten we're not quite sure how to handle documenting master which is 0.10.x and significantly different from 0.9.x.

Do you have plans to migrate forward when 0.10.x is released? How about you @migeorge?

[ZackMattor]

Hey @joshsmith, does 0.10.x provide a way to serialize with without going through ActiveController's render paths? If so I believe it requires a mention in the documentation.

The documentation on master should reflect 0.10.x, maybe provide a link to the 0.9.x documentation? Just my opinion :)

[joshsmith]

@criten want to open a PR that provides such a link to 0.9.x from README.md?

[joshsmith]

I'm not familiar enough with 0.10.x to provide a satisfactory answer to your broader question.
