This README would normally document whatever steps are necessary to get the application up and running.
Things you may want to cover:
- Ruby version
- System dependencies
- Configuration
- Database creation
- Database initialization
- How to run the test suite
- Services (job queues, cache servers, search engines, etc.)
- Deployment instructions
- ...
- add mimemagic gem:
gem 'mimemagic', '~> 0.3.8'. This fixes an issue with creating the uploader.
