Http://www.uiharness.com/quick-start/ - question related to installation

I installed UIHarness as:
meteor npm install --save-dev ui-harness as noted at http://www.uiharness.com/quick-start/

After this installation step, it further says: "Add a “start” script pointing to your entry folder…"
I found the “start” script in the ‘node_modules’ folder in my app folder. However, now want to know the following:

  1. What is the “entry folder”?
  2. Where should I place the package.json file in my app’s directory?

the writeup further notes “…and you are ready to code rediculously solid UI at crazy speeds!” :slight_smile:
