+### Using Sidekiq cluster by default (experimental)
+
+> [Introduced](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/4006) in GitLab 12.10.
+
+CAUTION: **Warning:**
+This feature is experimental.
+
+We're moving [Sidekiq cluster to
+core](https://gitlab.com/groups/gitlab-com/gl-infra/-/epics/181) and
+plan to make it the default way of starting Sidekiq.
+
+Set the following to start Sidekiq (cluster)
+process for handling for all queues (`/etc/gitlab/gitlab.rb`):
+
+```ruby
+sidekiq['enable'] = true
+sidekiq['cluster'] = true
+```
+
+All of the aforementioned configuration options for `sidekiq_cluster`
+are also available. By default, they will be configured as follows:
+
+```ruby
+sidekiq['experimental_queue_selector'] = false
+sidekiq['interval'] = nil
+sidekiq['max_concurrency'] = nil
+sidekiq['min_concurrency'] = nil
+sidekiq['negate'] = false
+sidekiq['queue_groups'] = ['*']
+```
+
+`sidekiq_cluster` must be disabled if you decide to configure the
+cluster as above.
+
+When disabling `sidekiq_cluster`, you must copy your configuration for
+`sidekiq_cluster`over to `sidekiq`. Anything configured for
+`sidekiq_cluster` will be overridden by the options for `sidekiq` when
+setting `sidekiq['cluster'] = true`.
+
+When using this feature, replace the `sidekiq` service with the
+`sidekiq-cluster`service for `gitlab-ctl` commands.
+
+For example, instead of:
+
+```shell
+sudo gitlab-ctl restart sidekiq
+```
+
+Use:
+
+```shell
+sudo gitlab-ctl restart sidekiq-cluster
+```
+
+The [concurrency](#managing-concurrency) and other options configured
+for Sidekiq will be respected.
+
+By default, logs for `sidekiq-cluster` go to `/var/log/gitlab/sidekiq`
+like regular Sidekiq logs.
