-    Wolverine.call('util/mexists', 'key1', 'key2', 'key3') #=> [0, 1, 0]

+## Configuration
+
+Available configuration options:
+
+* `Wolverine.config.redis` (default `Redis.new`)
+* `Wolverine.config.script_path` (default `Rails.root + 'app/wolverine'`)
+
+If you want to override one or both of these, doing so in an initializer is recommended but not required.
