+## 🔑 Key Concepts
+
+### Document Lifecycle
+```
+1. Upload → 2. OCR → 3. Classify → 4. Index → 5. Archive
+```
+
+### Components
+- **Consumer**: Processes incoming documents
+- **Classifier**: Auto-assigns tags/types using ML
+- **Index**: Makes documents searchable
+- **Workflow**: Automates document actions
+- **API**: Exposes functionality to frontend
+
+---
+
+## 📊 Module Map
+
+| Module | Purpose | Key Files |
+|--------|---------|-----------|
+| **documents** | Core DMS | consumer.py, classifier.py, models.py, views.py |
+| **paperless** | Framework | settings.py, celery.py, auth.py |

+| **paperless_tika** | Format parsing | parsers.py |
+
+---
+
+## 🔧 Common Tasks
+
+### Add New Document
+```python
+from documents.consumer import Consumer
+
+consumer = Consumer()
+doc_id = consumer.try_consume_file(
+    path="/path/to/document.pdf",
+    override_correspondent_id=5,
+    override_tag_ids=[1, 3, 7]
+)
+```
+
+### Search Documents
+```python
+from documents.index import DocumentIndex
+
+index = DocumentIndex()
+results = index.search("invoice 2023")
+```
+
+### Train Classifier
+```python
+from documents.classifier import DocumentClassifier
+
+classifier = DocumentClassifier()
+classifier.train()
+```
+
+### Create Workflow
+```python
+from documents.models import Workflow, WorkflowAction
+
+workflow = Workflow.objects.create(
+    name="Auto-file invoices",
+    enabled=True
+)
+
+action = WorkflowAction.objects.create(
+    workflow=workflow,
+    type="set_document_type",
+    value=2  # Invoice type ID
+)
+```
+
+---
+
+## 🌐 API Endpoints

+
+## 🗄️ Database Models
+
+### Core Models
+```python
+Document
+├── title: CharField
+├── content: TextField
+├── correspondent: ForeignKey → Correspondent
+├── document_type: ForeignKey → DocumentType
+├── tags: ManyToManyField → Tag
+├── storage_path: ForeignKey → StoragePath
+├── created: DateTimeField
+├── modified: DateTimeField
+├── owner: ForeignKey → User
+└── custom_fields: ManyToManyField → CustomFieldInstance
+
+Correspondent
+├── name: CharField
+├── match: CharField
+└── matching_algorithm: IntegerField
+
+DocumentType
+├── name: CharField
+└── match: CharField
+
+Tag
+├── name: CharField
+├── color: CharField
+└── is_inbox_tag: BooleanField
+
+Workflow
+├── name: CharField
+├── enabled: BooleanField
+├── triggers: ManyToManyField → WorkflowTrigger
+└── actions: ManyToManyField → WorkflowAction
+```
+
+---
+
+## ⚡ Performance Tips
+
+### Backend
+```python
+# ✅ Good: Use select_related for ForeignKey
+documents = Document.objects.select_related(
+    'correspondent', 'document_type'
+).all()
+
+# ✅ Good: Use prefetch_related for ManyToMany
+documents = Document.objects.prefetch_related(
+    'tags', 'custom_fields'
+).all()
+
+# ❌ Bad: N+1 queries
+for doc in Document.objects.all():
+    print(doc.correspondent.name)  # Extra query each time!
+```
+
+### Caching
+```python
+from django.core.cache import cache
+
+# Cache expensive operations
+def get_document_stats():
+    stats = cache.get('document_stats')
+    if stats is None:
+        stats = calculate_stats()
+        cache.set('document_stats', stats, 3600)
+    return stats
+```
+
+### Database Indexes
+```python
+# Add indexes in migrations
+migrations.AddIndex(
+    model_name='document',
+    index=models.Index(
+        fields=['correspondent', 'created'],
+        name='doc_corr_created_idx'
+    )
+)
+```
+

+

+
+## 🐛 Debugging Tips
+
+### Backend
+```python
+# Add logging
+import logging
+logger = logging.getLogger(__name__)
+
+def my_function():
+    logger.debug("Debug information")
+    logger.info("Important event")
+    logger.error("Something went wrong")
+
+# Django shell
+python manage.py shell
+>>> from documents.models import Document
+>>> Document.objects.count()
+
+# Run tests
+python manage.py test documents
+```
+
+### Frontend
+```typescript
+// Console logging
+console.log('Debug:', someVariable);
+console.error('Error:', error);
+
+// Angular DevTools
+// Install Chrome extension for debugging
+
+// Check network requests
+// Use browser DevTools Network tab
+```
+
+### Celery Tasks
+```bash
+# View running tasks
+celery -A paperless inspect active
+
+# View scheduled tasks
+celery -A paperless inspect scheduled
+
+# Purge queue
+celery -A paperless purge
+```
+
+---
+
+## 📦 Common Commands
+
+### Development
+```bash
+# Start development server
+python manage.py runserver
+
+# Start Celery worker
+celery -A paperless worker -l INFO
+
+# Run migrations
+python manage.py migrate
+
+# Create superuser
+python manage.py createsuperuser
+

+python manage.py collectstatic
+
+# Check deployment
+python manage.py check --deploy
+
+# Start with Gunicorn
+gunicorn paperless.wsgi:application
+```
+
+---
+
+## 🔍 Troubleshooting
+
+### Document not consuming
+1. Check file permissions
+2. Check Celery is running
+3. Check logs: `docker logs paperless-worker`
+4. Verify OCR languages installed
+
+### Search not working
+1. Rebuild index: `python manage.py document_index reindex`
+2. Check Whoosh index permissions
+3. Verify search settings
+
+### Classification not accurate
+1. Train classifier: `python manage.py document_classifier train`
+2. Need 50+ documents per category
+3. Check matching rules
+
+### Frontend not loading
+1. Check CORS settings
+2. Verify API_URL configuration
+3. Check browser console for errors
+4. Clear browser cache
+
+---
+
+## 📈 Monitoring
+
+### Key Metrics to Track
+- Document processing rate (docs/minute)
+- API response time (ms)
+- Search query time (ms)
+- Celery queue length
+- Database query count
+- Storage usage (GB)
+- Error rate (%)
+
+### Health Checks
+```python
+# Add to views.py
+def health_check(request):
+    checks = {
+        'database': check_database(),
+        'celery': check_celery(),
+        'redis': check_redis(),
+        'storage': check_storage(),
+    }
+    return JsonResponse(checks)
+```

+## 💡 Best Practices
+
+### Code Style
+```python
+# ✅ Good
+def process_document(document_id: int) -> Document:
+    """Process a document and return the result.
+    
+    Args:
+        document_id: ID of document to process
+        
+    Returns:
+        Processed document instance
+    """
+    document = Document.objects.get(id=document_id)
+    # ... processing logic
+    return document
+
+# ❌ Bad
+def proc(d):
+    x = Document.objects.get(id=d)
+    return x
+```
+
+### Error Handling
+```python
+# ✅ Good
+try:
+    document = Document.objects.get(id=doc_id)
+except Document.DoesNotExist:
+    logger.error(f"Document {doc_id} not found")
+    raise Http404("Document not found")
+except Exception as e:
+    logger.exception("Unexpected error")
+    raise
+
+# ❌ Bad
+try:
+    document = Document.objects.get(id=doc_id)
+except:
+    pass  # Silent failure!
+```
+
+### Testing
+```python
+# ✅ Good: Test important functionality
+class DocumentConsumerTest(TestCase):
+    def test_consume_pdf(self):
+        doc_id = consumer.try_consume_file('/path/to/test.pdf')
+        document = Document.objects.get(id=doc_id)
+        self.assertIsNotNone(document.content)
+        self.assertEqual(document.title, 'test')
