Bundle install - Could not locate Gemfile or .bundle/ directory

The bitnami.com install downloaded quickly and worked immediately. I ran their installer and discourse was up and running right away. I named the site, gave my email and password, and that was it. This is from their README

Bitnami Discourse Stack ships with the following software versions:

  • Discourse 1.4.6
  • Apache 2.4.18
  • PostgreSQL 9.4.6
  • Ruby 2.1.8
  • Rails 4.2.5.1
  • RubyGems 1.8.12

I want to look at discourse and see if I can use it for my image heavy web site. Someone said I’d need to write a plug in so I thought I’d look at doing that.
