+===========================
 Discount in purchase orders
 ===========================
 
 This module allows to define a discount per line in the purchase orders. This
 discount can be also negative, interpreting it as an increment.
 
-Known issues / Roadmap
-======================
+It also modifies the purchase order report to include the discount field in it.
+
+Installation
+============
+
+You need an Odoo/OCB installation updated up to at least on 27 august of 2015,
+containing revision `617ef49 <https://github.com/odoo/odoo/commit/617ef49959d027fab52e2be74aa4c0dc3ce60e30>`_
 
-* This module can be incompatible with other modules that modify purchase
-  prices, because it overwrites computation methods.
