+            Go to Prior to installing this module, if you have any existing products you should ensure they already have
+            a
+            unique reference (or no reference) set.<br/>
+            Products with a default_code of '/' or empty will automatically be assigned a code of "!!DP!!" followed
+            by the system id for that product.<br/>
+            Otherwise the setting of the unique constraint will fail and the module will fail to install.<br/>

+            Odoo product variants is very special.<br/>
+            When u create a product(not product template) with attribute, It would delete the first product, which
+            have no attribute.
+            So it's very normal that the first product variants begin wit ???-002.<br/>
+            And we make a rule that the product variants can only create after you create normal product template.
