+```
+
+### Debugging & Profiling
+```bash
+# Use pdbpp for debugging (installed via requirements-dev.txt)
+import pdb; pdb.set_trace()               # Set breakpoint in code
+
+# Use pyinstrument for profiling
+python manage.py runserver --noreload     # With pyinstrument middleware
+```
+
+## Code Style Guidelines
+
+### General Python Style
+- **PEP 8 compliant** - Follow standard Python style guide
+- **Line length**: 79 characters preferred; 119 acceptable for complex lines
+- **Long lines**: Use `# noqa: E501` comment when necessary (see settings.py)
+- **Indentation**: 4 spaces (no tabs)
+- **Encoding**: UTF-8
+
+### Import Organization
+Follow Django's import style (as seen in models.py, views.py, admin.py):
+
+```python
+# 1. Standard library imports
+import os
+import re
+from itertools import chain
+from functools import reduce
+
+# 2. Related third-party imports
+from django.db import models
+from django.conf import settings
+from django.contrib import admin
+from tinymce import models as tinymce
+
+# 3. Local application imports
+from ram.models import BaseModel, Image
+from ram.utils import DeduplicatedStorage, slugify
+from metadata.models import Scale, Manufacturer
+```
+
+**Key points:**
+- Group imports by category with blank lines between
+- Use `from module import specific` for commonly used items
+- Avoid `import *`
+- Use `as` for aliasing when needed (e.g., `tinymce.models as tinymce`)
+
+### Naming Conventions
+- **Classes**: `PascalCase` (e.g., `RollingStock`, `BaseModel`)
+- **Functions/methods**: `snake_case` (e.g., `get_items_per_page()`, `image_thumbnail()`)
+- **Variables**: `snake_case` (e.g., `road_number`, `item_number_slug`)
+- **Constants**: `UPPER_SNAKE_CASE` (e.g., `BASE_DIR`, `ALLOWED_HOSTS`)
+- **Private methods**: Prefix with `_` (e.g., `_internal_method()`)
+- **Model Meta options**: Use `verbose_name`, `verbose_name_plural`, `ordering`
+
+### Django Model Patterns
+
+```python
+class MyModel(BaseModel):  # Inherit from BaseModel for common fields
+    # Field order: relationships first, then data fields, then metadata
+    foreign_key = models.ForeignKey(OtherModel, on_delete=models.CASCADE)
+    name = models.CharField(max_length=128)
+    slug = models.SlugField(max_length=128, unique=True)
+    created = models.DateTimeField(auto_now_add=True)
+    
+    class Meta:
+        ordering = ["name"]
+        verbose_name = "My Model"
+        verbose_name_plural = "My Models"
+    
+    def __str__(self):
+        return self.name
+    
+    @property
+    def computed_field(self):
+        """Document properties with docstrings."""
+        return self.calculate_something()
+```
+
+**Model field conventions:**
+- Use `null=True, blank=True` for optional fields
+- Use `help_text` for user-facing field descriptions
+- Use `limit_choices_to` for filtered ForeignKey choices
+- Use `related_name` for reverse relations
+- Set `on_delete=models.CASCADE` explicitly
+- Use `default=None` with `null=True` for nullable fields
+
+### Admin Customization
+
+```python
+@admin.register(MyModel)
+class MyModelAdmin(admin.ModelAdmin):
+    list_display = ("name", "created", "custom_method")
+    list_filter = ("category", "created")
+    search_fields = ("name", "slug")
+    autocomplete_fields = ("foreign_key",)
+    readonly_fields = ("created", "updated")
+    save_as = True  # Enable "Save as new" button
+    
+    @admin.display(description="Custom Display")
+    def custom_method(self, obj):
+        return format_html('<strong>{}</strong>', obj.name)
+```
+
+### Error Handling
+```python
+# Use Django's exception classes
+from django.core.exceptions import ValidationError, ObjectDoesNotExist
+from django.http import Http404
+from django.db.utils import OperationalError, ProgrammingError
+
+# Handle database errors gracefully
+try:
+    config = get_site_conf()
+except (OperationalError, ProgrammingError):
+    config = default_config  # Provide fallback
+```
+
+### Type Hints
+- **Not currently used** in this project
+- Follow existing patterns without type hints unless explicitly adding them
+
+## Django-Specific Patterns
+
+### Using BaseModel
+All major models inherit from `ram.models.BaseModel`:
+```python
+from ram.models import BaseModel
+
+class MyModel(BaseModel):
+    # Automatically includes: uuid, description, notes, creation_time, 
+    # updated_time, published, obj_type, obj_label properties
+    pass
+```
+
+### Using PublicManager
+Models use `PublicManager` for filtering published items:
+```python
+from ram.managers import PublicManager
+
+objects = PublicManager()  # Only returns items where published=True
+```
+
+### Image and Document Patterns
+```python
+from ram.models import Image, Document, PrivateDocument
+
+class MyImage(Image):
+    my_model = models.ForeignKey(MyModel, on_delete=models.CASCADE)
+    # Inherits: order, image, image_thumbnail()
+
+class MyDocument(PrivateDocument):
+    my_model = models.ForeignKey(MyModel, on_delete=models.CASCADE)
+    # Inherits: description, file, private, creation_time, updated_time
+```
+
+### Using DeduplicatedStorage
+For media files that should be deduplicated:
+```python
+from ram.utils import DeduplicatedStorage
+
+image = models.ImageField(upload_to="images/", storage=DeduplicatedStorage)
+```
+
+## Testing Practices
+
+### Test Coverage
+The project has comprehensive test coverage:
+- **roster/tests.py**: RollingStock, RollingClass models (~340 lines, 19+ tests)
+- **metadata/tests.py**: Scale, Manufacturer, Company, etc. (~378 lines, 29+ tests)
+- **bookshelf/tests.py**: Book, Magazine, Catalog, TocEntry (~436 lines, 25+ tests)
+- **consist/tests.py**: Consist, ConsistItem (~315 lines, 15+ tests)
+- **ram/tests.py**: BaseModel, utility functions (~140 lines, 11+ tests)
+
+### Writing Tests
+```python
+from django.test import TestCase
+from django.core.exceptions import ValidationError
+from roster.models import RollingStock
+
+class RollingStockTestCase(TestCase):
+    def setUp(self):
+        """Set up test data."""
+        # Create necessary related objects
+        self.company = Company.objects.create(name="RGS", country="US")
+        self.scale = Scale.objects.create(scale="HO", ratio="1:87", tracks=16.5)
+        # ...
+    
+    def test_road_number_int_extraction(self):
+        """Test automatic extraction of integer from road number."""
+        stock = RollingStock.objects.create(
+            rolling_class=self.rolling_class,
+            road_number="RGS-42",
+            scale=self.scale,
+        )
+        self.assertEqual(stock.road_number_int, 42)
+    
+    def test_validation_error(self):
+        """Test that validation errors are raised correctly."""
+        with self.assertRaises(ValidationError):
+            # Test validation logic
+            pass
+```
+
+**Testing best practices:**
+- Use descriptive test method names with `test_` prefix
+- Include docstrings explaining what each test verifies
+- Create necessary test data in `setUp()` method
+- Test both success and failure cases
+- Use `assertRaises()` for exception testing
+- Test model properties, methods, and validation logic
+
+## Git & Version Control
+
+- Branch: `master` (main development branch)
+- CI runs on push and PR to master
+- Follow conventional commit messages
+- No pre-commit hooks configured (consider adding)
+
+## Additional Notes
+
+- **Settings override**: Use `ram/local_settings.py` for local configuration
+- **Debug mode**: `DEBUG = True` in settings.py (change for production)
+- **Database**: SQLite by default (in `storage/db.sqlite3`)
+- **Static files**: Bootstrap 5.3.8, Bootstrap Icons 1.13.1
+- **Rich text**: TinyMCE for HTMLField content
+- **REST API**: Disabled by default (`REST_ENABLED = False`)
+- **Security**: CSP middleware enabled, secure cookies in production

+### Asset lifecycle
+
+Data is collected to compute the asset usage and then the wear level of its components (eg. the engine).

+### Required mainentance forecast
+
+Eventually data is used to "forecast" any required maintenance, like for example the replacement of carbon brushes, gear and motor oiling.
