+### Cleanup Dead Jobs
+
+For sidekiq versions before 5.1 a `sidekiq_retries_exhausted` block is required per worker class.
+
+```ruby
+class MyWorker
+  sidekiq_retries_exhausted do |msg, _ex|
+    SidekiqUniqueJobs::Digests.delete_by(digest: msg['unique_digest']) if msg['unique_digest']
+  end
+end
+```
+
+Starting in v5.1, Sidekiq can also fire a global callback when a job dies:
+
+```ruby
+# this goes in your initializer
+Sidekiq.configure_server do |config|
+  config.death_handlers << ->(job, _ex) do
+    SidekiqUniqueJobs::Digests.delete_by(digest: job['unique_digest']) if job['unique_digest']
+  end
+end
+```
+
 ## Debugging
 
 There are two ways to display and remove keys regarding uniqueness. The console way and the command line way.
