# acts_as_api is a gem that aims to make the construction of JSON and XML
# responses in Rails 3, 4 and 5 easy and fun.
#
# Therefore it attaches a couple of helper methods to active record and
# the action controller base classes.
#
# acts_as_api uses the default serializers of your rails app and doesn't
# force you into more dependencies.
