NOTE:
      In the blog post, the lines of this code document are explained

      an Application class which usually involves writing the start
      method and configurable variables first before writing the name and
      description variables that appear in a earlier lines.

      If a step that has not yet been mentioned in the blog, skip it 
      and find the comment that matches what is being described.
