 ------------- | -------------
 full\_image\_name | The full docker image name that ufo builds. The "base" portion of the docker image name is defined in ufo/settings.yml. For example, the base portion is `tongueroo/hi` and the full image name is `tongueroo/hi:ufo-[timestamp]-[sha]`. The base name does not include the generated Docker tag, which contains a timestamp and git sha of the Dockerfile that is used.
 dockerfile\_port | Exposed port extracted from the Dockerfile of the project. 
 env_vars(text) | This method takes a block of text that contains the env values in key=value format and converts that block of text to the proper task definition json format.
 env_file(path) | This method takes an `.env` file which contains a simple key value list of environment variables and converts the list to the proper task definition json format.
+task_definition_name | The name of the task_definition.  So if the code looks like this `task_definition "demo-web" do`, the task_definition_name is "demo-web".
 
 To call the helper in task_definitions.rb you must add `helper.` in front.  So full\_image\_name  is called via `helper.full_image_name`.
 
 The 2 classes which provide these special helper methods are in [ufo/dsl.rb](https://github.com/tongueroo/ufo/blob/master/lib/ufo/dsl.rb) and [ufo/dsl/helper.rb](https://github.com/tongueroo/ufo/blob/master/lib/ufo/dsl/helper.rb). Refer to these classes for the full list of the special variables and methods.
