 Here is what is planned, roughly in the order it will be implemented:
 
-### Upgrade the layout so it follows django-app-template
+### Freshen Python and Django versions
 
-Status: In project
+Status: Pending
 
-Freshen the project structure, so it matches the django-app-template where 
-needed. For example move the demo code from apps into demo.
-
-Leave out the Docker related files - an SQLite database is all that's needed
-to demonstrate how the filter works.
+Freshen the python and Django versions supported. Remove unmaintained versions.
+For Django focus on LTS releases.
