+
+## Assigning New Users to Audiences
+
+To automatically assign new registered users to specific audiences, `dj-announcement-api` provides several methods. You can use the management commands (``generate_audiences`` and ``generate_profiles``) to assign related users to their appropriate audiences. However, for real-time assignment of new users, automating this within models, serializers, or signals may be more efficient. Below are three recommended approaches for automatic assignment, along with instructions on command usage.
+
+### Method 1: Using the Model's `save` Method
+
+
+In this approach, user-audience assignments are handled within the model's `save` method of the related model. This method can check if an instance is newly created and, if so, ensures that an `AnnouncementProfile` is generated automatically.
+
+Steps:
+1. Check for the audience corresponding to the model's verbose name, creating it if necessary.
+2. Create an `AnnouncementProfile` for the new user associated with the audience.
+
+```python
+from django.db import models
+from django_announcement.models import Audience, UserAnnouncementProfile
+
+class RelatedUserModel(models.Model):
+    user = models.OneToOneField("User", on_delete=models.CASCADE)
+    # additional fields
+
+    def save(self, *args, **kwargs):
+        is_new = self.pk is None
+        super().save(*args, **kwargs)
+
+        if is_new:
+            # Retrieve or create the audience based on model name
+            audience, _ = Audience.objects.get_or_create(
+                name=self._meta.verbose_name.title()
+            )
+
+            # Create the announcement profile for this user
+            profile, _ = UserAnnouncementProfile.objects.get_or_create(
+                user=self.user
+            )
+            profile.audiences.add(audience)
+            profile.save()
+```
+
+Using this method ensures that each time a user instance is created, audience assignment occurs immediately.
+
+### Method 2: In the Serializer's `create` Method
+
+For a more API-focused approach, handle audience assignments directly in the serializer's `create` method. This is ideal when user creation is managed through API endpoints.
+
+```python
+
+from rest_framework import serializers
+from django_announcement.models import Audience, UserAnnouncementProfile
+
+class RelatedUserModelSerializer(serializers.ModelSerializer):
+    class Meta:
+        model = RelatedUserModel
+        fields = '__all__'
+
+    def create(self, validated_data):
+        instance = super().create(validated_data)
+
+        # Fetch or create the audience
+        audience, _ = Audience.objects.get_or_create(
+            name=instance._meta.verbose_name.title()
+        )
+
+        # Assign the user to the audience
+        profile, _ = UserAnnouncementProfile.objects.get_or_create(
+            user=instance.user
+        )
+        profile.audiences.add(audience)
+        profile.save()
+
+        return instance
+```
+
+This approach is best for API-based workflows where user creation is handled via serializers.
+
+### Method 3: Using Signals
+
+Signals allow handling audience assignments whenever a new user instance is created, keeping assignment logic separate from models and serializers.
+
+Steps:
+1. Create a post-save signal for the user-related model.
+2. In the signal, retrieve or create the appropriate audience and announcement profile.
+
+```python
+from django.db.models.signals import post_save
+from django.dispatch import receiver
+from django_announcement.models import Audience, UserAnnouncementProfile
+from .models import RelatedUserModel
+
+@receiver(post_save, sender=RelatedUserModel)
+def assign_audience_to_new_user(sender, instance, created, **kwargs):
+    if created:
+        # Retrieve or create audience
+        audience, _ = Audience.objects.get_or_create(
+            name=instance._meta.verbose_name.title()
+        )
+
+        # Assign user to the audience
+        profile, _ = UserAnnouncementProfile.objects.get_or_create(
+            user=instance.user
+        )
+        profile.audiences.add(audience)
+        profile.save()
+```
+
+This approach enhances maintainability, particularly when user creation might occur in multiple parts of the codebase.
+
+## Using Management Commands for Batch Assignment
+
+If new roles or related models are added and require new audience creation, you can use the management commands:
+
+1. Run ``generate_audiences`` to create audiences based on related models if they don't already exist.
+2. Run ``generate_profiles`` to assign users to these audiences in bulk.
+
+These commands are useful for batch operations and can be combined with the methods above to automatically assign audiences to new users as they are created.
+
+## Conclusion
+
+For automating audience assignments to new users, choose the approach that best suits your workflow:
+
+- **Model save method** for tightly coupled functionality.
+- **Serializer `create` method** for API-driven workflows.
+- **Signals** for separation of concerns and modularity.
+- **Management commands** for batch assignment and new role or audience generation.
