These instructions will help you deploy your Finstagram app to Heroku (a web hosting service), so that the entire internet will be able to see and interact with your application! Before we get to deployment though, we need to make sure a couple of our files are setup properly.
Ensure your Gemfile file contains the following code (should match exactly).
source "https://rubygems.org"
gem 'rake'
gem 'activesupport'
