The README.rdoc currently links to http://api.rubyonrails.org/, but there's no ActiveResource documentation to be found there. I'd submit a pull request, but I can't find the actual home of the API docs, if there is one.
Ahh yes as activeresource is no longer part so there is no API documentation for this.
I think we can use rdoc for this to have a documentation like other gems.
I just found this documentation URL on rubygems: http://rubydoc.info/gems/activeresource/4.0.0/frames
Cool. I think this is good to use. We can add this in README
Update API doc url. Fix #110.
