+Loading with pre-built page on install
+======================================
+
+It is now possible to load the project with contents which shows how to use
+``django-cms`` and ``djangocms-frontend`` to add pages.
+
+Here is how to use the command:
+1. To list the available files in the ``democontent`` folder.
+   Run ``docker compose run --rm web python manage.py democontent``
+
+2. To add a page. Run ``docker compose run --rm web python manage.py democontent <FILE_PATH>``
+
+3. To add a page by force. Run ``docker compose run --rm web python manage.py democontent <FILE_PATH> --force``
+
