 title: Shared Variables
 ---
 
-Often times, you end up using the set of common variables across your task definitions for a project.  Ufo supports a shared variables concept to help with this.  You specify variables files in the `.ufo/variables` folder and they are made availale to your `.ufo/task_definitions.rb` as well as your `.ufo/templates` files.
+Often, you end up using the set of common variables across your task definitions for a project.  Ufo supports a shared variables concept to support this.  You specify variables files in the `.ufo/variables` folder and they are made available to your `.ufo/task_definitions.rb` as well as your `.ufo/templates` files.
 
 For example, given `variables/base.rb`:
 
 ```
-@image = helper.full_image_name # includes the git sha tongueroo/hi:ufo-[sha].
+@image = helper.full_image_name # includes the git sha tongueroo/demo-ufo:ufo-[sha].
 @cpu = 128
 @memory_reservation = 256
 @environment = helper.env_file(".env")
 ```
 
-You can now use `@image` in your `.ufo/templates/main.json.erb` without having to explicitly declare them in the `.ufo/task_definitions.rb` file.  Variables are automatically made available to all templates and the `task_definition.rb` file also.

 ## Layering
 
 Shared variables also support a concept called layering.  The `variables/base.rb` file is treated specially and will always be evaluated.  Additionally, ufo will also evaluate the `variables/[UFO_ENV].rb` according to what UFO_ENV's value is. Thanks to layering, you can easily override variables to suit different environments like `production` or `development`. For example:
 
 `.ufo/variables/base.rb`:
 
 ```ruby
-@image = helper.full_image_name # includes the git sha tongueroo/hi:ufo-[sha].
+@image = helper.full_image_name # includes the git sha tongueroo/demo-ufo:ufo-[sha].
 @cpu = 128
 @memory_reservation = 256
 @environment = helper.env_file(".env")
 ```
