+Configuration
+-------------

+To configure the application, don't edit `celutz/settings.py` directly, but
+instead create a file `celutz/local_settings.py` with your local modifications.

+Some things you should (must?) configure:
+
+- `SECRET_KEY`
+- `ALLOWED_HOSTS`
+- `DEBUG`
+- database configuration
+
+Then run the migrations:
+
     python manage.py migrate
+
+And create a superuser:

     python manage.py createsuperuser
