Building the Ember-data documentation in local

Due to slow network speed in my hometown, I would like to build the docs of ember-data in my notebook instead of browse the API at web site, but not similar to Ember.js, which can running npm build docs, I can not find any hints about how to build the Ember-data.

Relative SO question

I know how:

ember build -e production
cd dist\docs
ruby -run -e httpd . -p 3000

Maybe it should be add to the READMEā€¦
