+
+Route explains the steps you want to produce whereas the “picking zone” defines
+how operations are grouped according to their final source and destination
+location.
+
+This allows for example:
+
+* To parallelize picking operations in two main zone of a warehouse, splitting
+  them in two different picking type
+* To define pre-picking (wave) in some sub-zones, then roundtrip picking of the
+  sub-zone waves

+
+Configuration
+=============
+
+In Inventory Settings, you must have:
+
+ * Storage Locations
+ * Multi-Warehouses
+ * Multi-Step Routes
+
+Create an operation type and activate the "Is Zone" checkbox.
+The default destination location will be the destination location
+of the new operation inserted when a move has a source location which
+is a child of the type's source location.
+
+Known issues / Roadmap
+======================
+
+The concept of "zone" is duplicated with the zones introduced by
+"stock_location_zone" in
+https://github.com/OCA/stock-logistics-warehouse/pull/653
+They will be merged in the same concept. Note that considering the
+alpha version of this module, no data migration will be done.
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues <https://github.com/OCA/stock-logistics-warehouse/issues>`_.
+In case of trouble, please check there if your issue has already been reported.
