+Purchase Suggest Min Qty on Product
+===================================
+
+With this module, instead of using orderpoints, we add a *min_qty* field on product.product and we use this value as the minimum stock. This makes it easier for users to read and update the min_qty. But this should only be used if there is only 1 warehouse where we handle min stock rules (because, with this module, you cannot set min_qty per warehouse or per stock location).
+
+This module has been written by Alexis de Lattre from Akretion <alexis.delattre@akretion.com>.
