# The Configuration class is responsible for holding the configuration settings
# for the Anyicon gem. It provides a default set of icon collections that can be
# customized by the user.
module Anyicon
  # Example usage:
  #
  #   Anyicon.configure do |config|
  #     config.collections = {
  #       custom_collection: {
  #         repo: 'user/repo',
  #         path: 'path/to/icons',
  #         branch: 'main'
  #       }
  #     }
  #   end

  # The class also allows setting additional configuration options such as
  # `default_class`, which can be used to apply a default CSS class to every icon.
