I'm trying to use the new mongoid version 6.0.0.rc0 with a rails 5 app.

There is no documentation here, and I can't find docs for version 6.x on how to remove all the Active record stuff from my rails app so that I can generate a mongoid.yml file.

I've removed my database.yml file and tried to run:

$ rails g mongoid:config

and I get the error:

/Users/tomcaflisch/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/application/configuration.rb:143:in `database_configuration': Cannot load `Rails.application.database_configuration`:
Could not load database configuration. No such file - ["config/database.yml"] (RuntimeError)

How can I get past this error? I'm assuming I need to change some active record references somewhere?
