+
+Use Cases / Context
+===================
+
+Sometimes you need to compute sales price based on values obtained from
+custom sources. Eg you receive your purchase prices dynamically from a
+vendor using API.
+
+However by default Odoo has only limited options for a pricelist price
+base:
+
+-  Sales Price
+-  Cost
+-  Other Pricelist
+
+Configuration
+=============
+
+Create a new one or select an existing pricelist with "Computation" mode
+set to "Formula".
+
+In the pricelist:
+
+-  Select "Formula" in the "Computation" selector.
+-  Select "Custom Value" in the "Based on" field.
+
+Usage
+=====
+
+This is a technical module which means it's designed to be used as a
+part of custom solutions. You need to add your price as
+**custom_base_price**\ ​ kwargs key when calling **\_get_product_price**
+function of the **product.pricelist** ​model.
