 ## Installation
 
 Add this line to your application’s Gemfile:
 
 ```ruby
-gem 'cacheflow'
+gem 'cacheflow', group: :development
 ```
 
 When your log level is set to `DEBUG` (Rails default in development), all commands to Memcached and Redis are logged.
+
+## Features

+```
+
+To silence logging for only [Sidekiq](https://github.com/mperham/sidekiq) commands, create an initializer with:
+
+```ruby
+Cacheflow.silence_sidekiq!
+```
