+Removal of catalog promotion
+---------------------------------------
+
+Removal of the catalog promotion consists in turning off the promotion, recalculation of the catalog
+and the actual removal of the promotion resource. By using catalog promotions in asynchronous mode,
+it is necessary to start the worker for two transports, the **main** transport is responsible for recalculation of the catalog
+and the **catalog_promotion_removal** transport is self explanatory. The order of transports provided as the command arguments is important,
+it is responsible for the priority of consumed messages:
+
+.. code-block:: bash
+
+    php bin/console messenger:consume main catalog_promotion_removal
+
+For synchronous processing, no additional configuration is required.
