+### Using `ConfigDefault::Struct` without configuration load

+You can use `ConfigDefault::Struct` to achive ability to create config object from Hash objects.
+Here an example of creation struct object on the fly:
+
+```ruby
+config_on_the_fly = { first: { second: { third: "option" } } }
+config = ConfigDefault::Struct.new(attributes: config_on_the_fly, recursive: true)

+config.first.second.third
+# => "option"
+config.first.lolkek
+# => StandardError: There is no option :lolkek in configuration.

+`ConfigDefault::Struct` supports `recursive` and `allow_nil` options.
