2. def read_content(request):: Defines the read_content function, which will handle HTTP requests. The function takes a request object containing information about the client's request;

3. all_notes = Note.objects.all(): Utilizes Django's Object-Relational Mapping (ORM) to query the database and retrieve all objects of the Note model`;

4. return HttpResponse(all_notes): We are sending information to the HTML template.
