 As the generator requires node and several npm modules this image bakes in the dependencies to reduce the time taken to deploy applications.
 
-## Construction
-
-This image uses the standard node.js 4.2.2 image. 
-
-It is tied into the docker hub and will automatically include upstream changes.
-
-## Usage
-
-**waiting for inclusion** 
-
-You will be able to do 
-
-    yo angular-fullstack:docker
-    
-Which will add the Dockerfile to your dist folder
-
-This can then be built using the standard docker tools
-
-The Dockerfile will survive
-    
-    grunt clean
-    
-operations

-## Tracking
-
-As angular-fullstack evolves and npm references change this repo will track the version numbers and create a new branch which will then create a new docker container per branch
