1. Add `django_scylla` to `INSTALLED_APPS` in your `settings.py` file:

INSTALLED_APPS = ('django_scylla',) + INSTALLED_APPS

2. Change `DATABASES` setting:

DATABASES = {
            'default': {
                'ENGINE': 'django_scylla',
                'NAME': 'db',

                'HOST': 'db1.example.com,db2.example.com,db3.example.com',
                'OPTIONS': {
                    'replication': {
                        'strategy_class': ...,
                        'replication_factor': ...
                    },
                    'execution_profile': {
                        'load_balancing_policy': ...,
                        'retry_policy': ...,
                        'consistency_level': ...,
                        'serial_consistency_level': ...,
                        'request_timeout': ...,
                        'speculative_execution_policy': ...
                    }
                    'connection': {
                        # Full list of connection options can be found here: https://docs.datastax.com/en/developer/python-driver/3.26/api/cassandra/cluster/
                        'cql_version': ...,
                        'protocol_version': ...
                        'compression': ...,
                        'consistency': ...,
                        'lazy_connect': ...,
                        'retry_connect': ...,
                    }
                }
            }
        }

3. Define some model:

# myapp/models.py

from django.db import models

class Person(models.Model):
            first_name = models.CharField(max_length=30)
            last_name = models.CharField(max_length=30)

4. Connect to ScyllaDB and create a keyspace.
5. Run `./manage.py makemigrations && ./manage.py migrate`
6. Done!
