I’m guessing it’s something simple, but I have this error when trying to use ROM in my sinatra application:

`undefined method`setup’ for ROM:Module (NoMethodError)`

This is all from using the basic one-liner provided in the docs:

`ROM.setup(:sql, 'sqlite:///path/to/db.sqlite')`

The setup was changed in 1.0.0. Please take a look at [the announcement](http://rom-rb.org/blog/2015/11/24/first-beta-of-rom-1-0-0-has-been-released/) post for the first 1.0 beta where it’s explained.

Updated docs will be published later this week on [rom-rb.org](http://rom-rb.org).
