+=================
+POS Lot Selection
+=================
+
+This module allows to pick between existing lots in POS frontend.
+
+Configuration
+=============
+
+1. Go to *Inventory > Settings* and set the option *Track lots or serial
+   numbers*
+2. Chose a product that is stockable, go to its *Inventory*
+   tab, and set *Tracking* to *By Lots*.
+3. Go to its *Sales* tab and set it as *Available in the Point of Sale*.
+4. Click on *Update Qty On Hand*, chose the same location configured in the
+   POS you want the lot available in; write a quantity; unfold the *Lot/Serial
+   Number* field and pick create one if none is available yet.
+5. Create a new lot with the serial number of your choice.
+
+Usage
+=====
+
+* Open a POS Session.
+* Choose a product with required lot.
+* There is a new select field with the lots available for that product.
+* If lot quantity can't cover the order line demand it won't be available to
+  pick.
+* If there were many lots to fill the value of one of them can be propagated to
+  the rest with the new clone control on the right of the lot field.

+
+Known issues / Roadmap
+======================
+
+* Lot selection is only available when the POS is online. In offline mode the
+  select isn't loaded and the lot has to be manually set.
