Install ruby 2.2 and Node 0.12. Hopefully not forgetting anything:
In server/
$ bundle
$ rake db:migrate
$ rake app:import_companies
$ rails s
In client/
$ npm install
$ npm install -g bower
$ bower install
$ ember server --proxy http://localhost:3000/
Definitely quick and dirty -- sorry, ran out of time for niceties like tests, refactoring, cross-browser testing etc.!
Ran into json rendering performance issues when using the active_model_serializers gem (~10x vs raw jbuilder). Opted to hand-build the Ember-expected structure in jbuilder.
