+#### Releasing the feature
+
+1. In `ee/app/replicators/geo/widget_replicator.rb`, delete the `self.replication_enabled_by_default?` method:
+
+   ```ruby
+   module Geo
+     class WidgetReplicator < Gitlab::Geo::Replicator
+       ...
+
+       # REMOVE THIS METHOD
+       def self.replication_enabled_by_default?

+       end
+       # REMOVE THIS METHOD
+
+       ...
+     end
+   end
+   ```
+
+1. In `ee/app/graphql/types/geo/geo_node_type.rb`, remove the `feature_flag` option for the released type:
+
+   ```ruby
+   field :widget_registries, ::Types::Geo::WidgetRegistryType.connection_type,
+         null: true,
+         resolver: ::Resolvers::Geo::WidgetRegistriesResolver,

+         feature_flag: :geo_widget_replication # REMOVE THIS LINE
