 * Add an initializer to configure looksist
 
 ``` ruby
 Looksist.configure do |looksist|
-      looksist.lookup_store = Redis.new(:url => (ENV['REDIS_URL'], :driver => :hiredis)
+      looksist.lookup_store = Redis.new(:url => ENV['REDIS_URL'], :driver => :hiredis)
       looksist.driver =  Looksist::Serializers::Her
 end
 ```
 You need to specify the driver to manage the attributes. In this case, we use [HER](https://github.com/remiprev/her). You can add support for ActiveResource or ActiveRecord as needed (also refer to specs for free form usage without a driver).

+### Controlling the L2 cache
+Looksist has support for an in memory L2 cache which it uses to optimize redis lookups. To disable L2 cache initialize looksists as below. 
+
+* Note that in no L2 cache mode, all lookups would go to redis and the gem would not optimize redundant lookups.
+* Hash based lookups would still see optimizations which come from performing unique on keys when injecting values.

+Looksist.configure do |looksist|

+      looksist.driver =  Looksist::Serializers::Her
