uninitialized constant Rack::Indexable (NameError)

[snoblenet]

I have indexable in the Gemfile and have confirmed it's loaded in Gemfile.lock.

In config.ru I have:

require 'indexable'
use Rack::Indexable

On rails console or foreman start I get:

16:16:33 web.1    | config.ru:8:in `block in <main>': uninitialized constant Rack::Indexable (NameError)
16:16:33 web.1    |     from /Users/steven/.rvm/gems/ruby-2.1.3/gems/rack-1.5.2/lib/rack/builder.rb:55:in `instance_eval'
16:16:33 web.1    |     from /Users/steven/.rvm/gems/ruby-2.1.3/gems/rack-1.5.2/lib/rack/builder.rb:55:in `initialize'
16:16:33 web.1    |     from config.ru:1:in `new'
16:16:33 web.1    |     from config.ru:1:in `<main>'

Why? And how to fix?

Thanks,

Steven.

You are supposed to use Indexable::Middleware, I have updated the documentation to reflect the same.
