  1. Fork our GitHub repository:
  2. Clone the fork to your computer
  3. Run bundle install to install all of the dependencies
  4. Create a database.yml file in config. The config directory contains an example database.yml for PostgreSQL.
  5. Create an omniauth.yml file in config. The config directory contains an example omniauth.yml file.
  6. Create a config/initializers/secret_token.rb file. The config/initializers directory contains an example secret_token.rb file with instructions for generating a secret token.

$ rake db:create
$ rake db:schema:load

Finally, run the test suite to make sure everything is working correctly:
