I am not sure how to do the Ruby Challenge. Please help

The Ruby Challenge is to do the following: Create a module called ClassMethods inside of the Inventory module.

module Inventory end

class Shirt include Inventory attr_accessor :attributes

def initialize(attributes) @attributes = attributes end end

store.rb 
module Inventory
end

class Shirt
  include Inventory
  attr_accessor :attributes

  def initialize(attributes)
    @attributes = attributes
  end
end

Hi Michael!

So, it's important to understand that the question is asking you to create a module inside the Inventory module. Modules in Ruby need to begin with the module keyword followed by the name of the module, and then close with the end keyword. As an example, if I want to create a module within a module, it would look something like this:

module Inventory
   module MyModule
   end
end

Hopefully that helps to clarify the question! Jason goes on in the video to explain how to extend and include the module, which I'm sure will be next on the list of questions. If you need further help, don't hesitate to ask!
