"API docs" as part of Rails 5

Hi all,

With Rails 5 coming up, are there any conversations or efforts to make API documentation (for end users, not for the framework itself) a “first class citizen”?

Documenting APIs is hard and keeping it up to date is hard. There are a number of tools to do this already, but I’ve found that they either:

  1. have to be maintained separately
  2. involve ugly meta code / comments in your codebase
  3. don’t have large communities around them
    With Rails 5 offering the “API only” mode, I’m wondering if it would be useful to approach API documentation as a problem that Rails can solve?

Thanks!

PS, I’ve done a cursory search in Github Issues for this and in this Google Group, but don’t see anything relevant. Apologies if I missed something.
