[octonato]

Relates to #150. It's not a fix, but at least document how to workaround it.

@renatocaval i'm looking at this a little more closely and thinking about inlining these notes into the larger example in order to be more consistent with existing notes. in looking, i notice that there are already notes about these details being "Required". i could simply include a note for each of those to set to null if not wanting to set them, but i'm wondering if they would be noticed. do you think they would have clarified the issue that you were having, or would you have overlooked the note there?

Hmm, indeed. Maybe we should have just a short heads-up.

I find it easier to miss the instructions if it's in the form of comments in the config file. As you can see, I didn't read them.
