 ## Using with Sidekiq
-This gem uses a Rack middleware to clear the store object after every request, but that doesn't translate well to background processing with [Sidekiq](https://github.com/mperham/sidekiq).
 
-A companion library, [request_store-sidekiq](https://rubygems.org/gems/request_store-sidekiq) creates a Sidekiq middleware that will ensure the store is cleared after each job is processed, for security and consistency with how this is done in Rack.
