+Organize Settings Module
+========================
+
+First, transform the settings.py into a directory containing individual settings files for development, production, and testing. Here's the structure you'll create:
+
+```bash
+
+backend/
+backend/
+settings/
+__init__.py
+base.py       # Common settings
+development.py  # Development-specific settings
+production.py  # Production-specific settings
+testing.py     # Testing-specific settings
+```
+
+- base.py: Contains settings common to all environments (e.g., INSTALLED_APPS, MIDDLEWARE).
+- development.py: Settings for the development environment (e.g., DEBUG = True, database configurations for development).
+- production.py: Production-specific settings (e.g., DEBUG = False, security settings, database configurations for production).
+- testing.py: Settings used for running tests (e.g., using an in-memory database like SQLite for faster test execution).
+
+### Using the Settings
+
+To use these settings, you'll specify the appropriate settings module when running Django commands. For example:
+
+<br>
+
+#### For development:
+
+```bash
+
+python manage.py runserver --settings=backend.settings.development
+```
+
+<br>
+
+#### For production:
+
+```bash
+python manage.py collectstatic --settings=backend.settings.production
+python manage.py migrate --settings=backend.settings.production
+```
+
+<br>
+
+#### For testing:
+
+```bash
+python manage.py test --settings=backend.settings.testing
+```
+
+<br>
+
+You can also set the DJANGO_SETTINGS_MODULE environment variable in your development, production, or CI/CD environment to point to the correct settings module, simplifying command usage.
