+Inheritance
+===========
+
+If you want to generate barcode for another model, you can create a custom
+module that inherits on 'barcodes_generate' and inherit your model like that:
+
+class MyModel(models.Model):
+    _name = 'my.model'
+    _inherit = ['my.model', 'barcode.generate.mixin']
+
+class barcode_rule(models.Model):
+    _inherit = 'barcode.rule'
+
+    generate_model = fields.Selection(selection_add=[('my.model', 'My Model')])
+
+Finally, you should inherit your model view adding buttons and fields.
+
+Note
+----
+
+Your model should have a field 'barcode' defined.
