+==============================
+Sale Contact Subtype Followers
+==============================
+
+* This module removes the functionality of the system that assigns different 
+  child contacts depending on their type. In this way, the contact type is only
+  used for informational purposes and the shipping address is not automatically
+  assigned, for example, in pickings on delivery address.
+* To allow this functionality to work anywhere in the system, this code replaces
+  the values ​​generated by the "address_get" method with the same selected base
+  contact.
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues
+<https://github.com/avanzosc/sale-addons/issues>`_. In case of trouble,
+please check there if your issue has already been reported. If you spotted
+it first, help us smash it by providing detailed and welcomed feedback.
+
+Do not contact contributors directly about support or help with technical issues.
