+module ActiveModel
+
+  # == Active Model Basic Model
+  #
+  # Includes the required interface for an object to interact with <tt>ActionPack</tt>,
+  # using different <tt>ActiveModel</tt> modules. It includes model name introspections,
+  # conversions, translations and validations. Besides that, it allows you to
+  # initialize the object with a hash of attributes, pretty much like
+  # <tt>ActiveRecord</tt> does.
+  #
+  # A minimal implementation could be:
+  #
+  #   class Person
+  #     include ActiveModel::Model
+  #     attr_accessor :name, :age
+  #   end
+  #
+  #   person = Person.new(:name => 'bob', :age => '18')
+  #   person.name # => 'bob'
+  #   person.age # => 18
+  #
+  # Note that, by default, <tt>ActiveModel::Model</tt> implements <tt>persisted?</tt> to
+  # return <tt>false</tt>, which is the most common case. You may want to override it
+  # in your class to simulate a different scenario:
+  #
+  #   class Person
+  #     include ActiveModel::Model
+  #     attr_accessor :id, :name
+  #
+  #     def persisted?
+  #       self.id == 1
+  #     end
+  #   end
+  #
+  #   person = Person.new(:id => 1, :name => 'bob')
+  #   person.persisted? # => true
+  #
+  # Also, if for some reason you need to run code on <tt>initialize</tt>, make sure you
+  # call super if you want the attributes hash initialization to happen.
+  #
+  #   class Person
+  #     include ActiveModel::Model
+  #     attr_accessor :id, :name, :omg
+  #
+  #     def initialize(attributes={})
+  #       super
+  #       @omg ||= true
+  #     end
+  #   end
+  #
+  #   person = Person.new(:id => 1, :name => 'bob')
+  #   person.omg # => true
+  #
+  # For more detailed information on other functionalities available, please refer
+  # to the specific modules included in <tt>ActiveModel::Model</tt> (see below).
