+Please remember that ENVied only **reads** from ENV; it doesn't mutate ENV.
 Don't let setting a default for, say `RAILS_ENV`, give you the impression that `ENV['RAILS_ENV']` is set.
 As a rule of thumb you should only use defaults:
 * for local development
 * for ENV-variables that are solely used by your application (i.e. for `ENV['STAFF_EMAILS']`, not for `ENV['RAILS_ENV']`)
