+**Important Note: Django 3 has introduced it's own enumeration types: https://docs.djangoproject.com/en/3.1/ref/models/fields/#enumeration-types**
+
+**This makes `django-enum-choices` redundant when used with Django >= `3.0`.**
+
+**If you are using `django-enum-choices` and you want to upgrade your project to Django >= `3.0` you can refer to the guide in the wiki:  [Migrating to Django 3](https://github.com/HackSoftware/django-enum-choices/wiki/Migrating-to-Django-3)**
+
+**We will continue to support the compatibility with Django's versions prior to `3.0`.**
