+===================================
+Stock Account Inventory Revaluation
+===================================
+
+If your company runs a perpetual inventory system, you may need to perform
+inventory revaluation.
+
+You can re-valuate inventory values by:
+
+* Changing the price for a specific product. The inventory price is changed
+  and inventory value is recalculated according to the new price. In case of
+  real price, you can select which quants you want to change the price on.
+
+* Changing the value of the inventory. The quantity of inventory remains
+  unchanged, resulting in a change in the price.
+
+
+
+Configuration
+=============
+
+
+* Go to *Inventory / Configuration / Products / Product Categories* and
+  define, for each category, a Valuation Increase Account and a Valuation
+  Decrease Account. These accounts will be used as contra-accounts to the
+  Stock Valuation Account during the inventory re-valuation.
+
+* Users willing to access to the Inventory Revaluation menu should be
+  members of the group "Manage Inventory Valuation and Costing Methods".
+
+
+Usage
+=====
+
+* Go to *Inventory / Inventory Control / Inventory Revaluation / Products*
+  to create a new Inventory Revaluation.
