+# Django Development Workflow and Project Structure
+
+## 1. Project Setup
+
+```
+my_project/
+    manage.py
+    my_project/
+        __init__.py
+        settings.py
+        urls.py
+        asgi.py
+        wsgi.py
+    apps/
+        app1/
+            __init__.py
+            admin.py
+            apps.py
+            models.py
+            tests.py
+            views.py
+            urls.py
+            migrations/
+            templates/

+            static/
+                app1/
+        app2/
+            # Similar structure to app1
+    templates/
+    static/
+    media/
+    requirements.txt
+    .gitignore
+    README.md
+```
+
+## 2. Development Workflow
+
+1. **Plan Your Project**
+   - Define models, views, and URL structure
+   - Create a list of features and prioritize them
+
+2. **Set Up the Project**
+   - Create a virtual environment
+   - Install Django and other dependencies
+   - Start a new Django project
+   - Configure settings.py (database, static files, etc.)
+
+3. **Create Apps**
+   - Use `python manage.py startapp` for each major feature
+   - Move apps into the `apps/` directory for better organization
+
+4. **Define Models**
+   - Design your data schema in `models.py`
+   - Create migrations: `python manage.py makemigrations`
+   - Apply migrations: `python manage.py migrate`
+
+5. **Create Views and Templates**
+   - Implement view logic in `views.py`
+   - Create corresponding HTML templates
+
+6. **Configure URLs**
+   - Set up URL patterns in `urls.py` (both project and app level)
+
+7. **Implement Forms**
+   - Create forms for data input and processing
+
+8. **Add Static Files**
+   - Organize CSS, JavaScript, and images in static directories
+
+9. **Set Up Admin Interface**
+   - Customize `admin.py` for each app
+
+10. **Write Tests**
+    - Create unit tests for models, views, and forms
+    - Run tests frequently: `python manage.py test`
+
+11. **Implement Authentication and Authorization**
+    - Set up user registration, login, and permissions
+
+12. **Continuous Development and Iteration**
+    - Regularly commit changes to version control
+    - Refactor code as needed
+    - Add new features incrementally
+
+13. **Documentation**
+    - Maintain a README.md with project setup instructions
+    - Document complex parts of your code
+
+14. **Deployment Preparation**
+    - Set up production settings
+    - Collect static files: `python manage.py collectstatic`
+    - Configure your web server (e.g., Gunicorn, Nginx)
+
+## Best Practices
+
+- Follow PEP 8 style guide for Python code
+- Use meaningful names for variables, functions, and classes
+- Keep views thin, move business logic to models or separate service classes
+- Use class-based views for reusable, DRY code
+- Leverage Django's built-in features (forms, authentication, admin) when possible
+- Use environment variables for sensitive information
+- Regularly update dependencies and Django version
