+This module adds *Product Pack* functionality to sales orders. You can choose
+a *Pack* in *sales order lines* and see different behaviors depending on
+"Pack type" and "Pack component price" fields options selected on this *Pack*.

+
+Usage
+=====
+
+To use this module, you need to:
+
+#. Go to *Sales > Products > Products*, create or select a product and check
+   *Is Pack?*
+#. Set "Product type" and "Pack component price" fields in the *Pack* page.
+#. Add the products to be included in it.
+#. Go to *Sales > Orders > Quotations* and create a Quotation.
+#. Add a product that has checked "Is Pack?"
+#. Save data and you will see an specific behavior depending on "Pack type" and
+   "Pack component price" fields options selected on this *Pack*. For example,
+   for products that has *Detailed* option selected in "Pack type" field you
+   will see one *sale order line* per component that belong to this Pack.
+   (See *Product pack* module README.rst file)
+
+Known issues / Roadmap
+======================
+
+* If this module is installed and stock module is installed too, when you
+  create a Sale order for a *Non detailed* Pack and you confirm it,
+  a *Stock picking* is not created with the storable components of that Pack.
+  So, add a new module called *sale_stock_product_pack* that adds that feature.
