 By default, the adapter will use `Redis.new` as it's connection which uses the defaults in that gem.
 You can pass in your own connection to use instead, useful for specifying a server and other options.
 
 ```ruby
 # Use the default connection
+require 'redis_adapter'
+
 adapter = Hikki::Adapters::RedisAdapter.new
 
 # Use a specific connection
 redis = Redis.new(:url => "redis://:p4ssw0rd@10.0.1.1:6380/15")
 adapter = Hikki::Adapters::RedisAdapter.new(redis)
