-* In POS configuration enable multiple pricelists
-* There will be a checkbox "Hide Pricelist Button"
-* If checked pricelist selection button will be hidden in POS Screen
+In POS configuration, enable advanced pricelists and add all pricelists with reference to pricelists to be used in POS in "Available Pricelists".
+
+To restrict POS user from selecting any pricelist (therefore only use prices from "Default Pricelist"), enable boolean "Hide Pricelist Button"
+
+To restrict POS user's pricelist selection to a set of pricelists, add them to "Selectable Pricelists".
+Note: make sure "Default Pricelist" is among "Selectable Pricelists".
