+=====================
+Stock Demand Estimate
+=====================
+
+This module allows to create demand estimates for a given product and
+location, on configurable time periods.
+
+The module does not provide in itself any specific usage of the estimates.
+
+Installation
+============
+
+This module relies on the OCA module '2D matrix for x2many fields', and can
+be downloaded from:
+* Github: https://github.com/OCA/web/tree/8.0/web_widget_x2many_2d_matrix
+
+
+Usage
+=====
+
+Go to 'Warehouse / Configuration / Demand Estimate Periods' and define your
+estimating periods (monthly or weekly).
+
+
+Go to 'Warehouse / Demand Planning / Create Demand Estimates' to create or
+update your demand estimates.
+
+Go to 'Warehouse / Demand Planning / Demand Estimates' to review the
+estimates created.
