+
+## Development Process
+
+1. Fork the repo and create your branch from `develop`
+2. Install development dependencies:
+   ```bash
+   pip install -e ".[dev]"
+   ```
+3. Run tests to ensure everything is working:
+   ```bash
+   pytest
+   ```
+4. Make your changes and add tests
+5. Run the test suite again
+6. Push to your fork and submit a pull request
+
+## Testing
+
+We use pytest for our test suite. To run tests:
+
+```bash
+# Run all tests
+pytest
+
+# Run specific test file
+pytest tests/test_fields.py
+
+# Run with coverage report
+pytest --cov=seo_optimizer
+```
+
+### Writing Tests
+
+* Write test docstrings
+* Each test should have a single assertion
+* Use descriptive test names
+* Follow the Arrange-Act-Assert pattern
+
+Example:
+```python
+def test_metadata_field_validates_max_length():
+    """Test that MetadataField correctly validates max_length."""
+    # Arrange
+    field = MetadataField(max_length=10)
+    
+    # Act & Assert
+    with pytest.raises(ValidationError):
+        field.clean("This is too long")
+```
+
+## Style Guide
+
+We follow PEP 8 with some modifications:
+
+* Line length limit is 100 characters
+* Use double quotes for strings
+* Use trailing commas in multi-line structures
+* Sort imports using isort
+
+Use black for code formatting:
+```bash
+black seo_optimizer
+```
+
+## Documentation
+
+* Use Google-style docstrings
+* Update the README.md if needed
+* Add docstrings to all public methods
+* Include code examples in docstrings
+* Update type hints
+
+Example:
+```python
+def get_metadata(
+    self,
+    path: str,
+    language: Optional[str] = None
+) -> Dict[str, Any]:
+    """Get metadata for the given path and language.
+    
+    Args:
+        path: The URL path to get metadata for
+        language: Optional language code (e.g., 'en', 'es')
+        
+    Returns:
+        Dictionary containing metadata fields
+        
+    Example:
+        >>> meta = MetadataManager().get_metadata('/products/')
+        >>> print(meta['title'])
+        'Our Products'
+    """
+```
+
+## Commit Messages
+
+* Use the present tense ("Add feature" not "Added feature")
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
+* Limit the first line to 72 characters or less
+* Reference issues and pull requests liberally after the first line
+
+Example:

+### Core Components
+
+#### MetadataField
+
+The base field type for SEO metadata:
+
+```python
+from seo_optimizer import MetadataField
+
+title = MetadataField(
+    max_length=70,
+    required=True,
+    template_support=True
+)
+```
+
+**Parameters:**
+- `max_length`: Maximum length of the field value
+- `required`: Whether the field is required
+- `template_support`: Enable Django template syntax in field values
+- `validators`: List of validation functions
+
+#### Specialized Fields
+
+```python
+from seo_optimizer import KeywordsField, RobotsField, OpenGraphField
+
+# Keywords with automatic comma separation
+keywords = KeywordsField(max_keywords=10)
+
+# Robots directives with validation
+robots = RobotsField(default="index,follow")
+
+# Open Graph metadata
+og = OpenGraphField(
+    title_max_length=95,
+    description_max_length=200
+)
+```
+
+#### AsyncMetadataManager
+
+For high-performance async metadata operations:
+
+```python
+from seo_optimizer import AsyncMetadataManager
+
+async def get_meta(path):
+    manager = AsyncMetadataManager()
+    return await manager.get_metadata(path)
+```
+
+### Configuration Options
+
+Available settings in `settings.py`:
+
+```python
+SEO_OPTIMIZER = {
+    'CACHE_TIMEOUT': 3600,  # 1 hour
+    'ASYNC_ENABLED': True,
+    'MAX_ASYNC_WORKERS': 10,
+    'USE_SITES_FRAMEWORK': True,
+    'DEFAULT_LANGUAGE': 'en',
+}
+```
+
+## User Guide
+
+### Basic Setup
+
+1. Install the package:
+```bash
+pip install django-seo-optimizer
+```
+
+2. Add to INSTALLED_APPS:
+```python
+INSTALLED_APPS = [
+    ...
+    'seo_optimizer',
+]
+```
+
+3. Run migrations:
+```bash
+python manage.py migrate seo_optimizer
+```
+
+### Metadata Configuration
+
+Create a metadata configuration file (e.g., `seo.py`):
+
+```python
+from seo_optimizer import register_metadata, MetadataField
+
+@register_metadata
+class BlogMetadata:
+    title = MetadataField(max_length=70)
+    description = MetadataField(max_length=160)
+    keywords = KeywordsField()
+    
+    class Meta:
+        use_cache = True
+        use_sites = True
+        use_i18n = True
+```
+
+### Template Integration
+
+```html
+{% load seo_tags %}
+
+{% get_metadata as meta %}
+<head>
+    <title>{{ meta.title }}</title>
+    <meta name="description" content="{{ meta.description }}">
+    <meta name="keywords" content="{{ meta.keywords }}">
+    {% if meta.og %}
+        <meta property="og:title" content="{{ meta.og.title }}">
+        <meta property="og:description" content="{{ meta.og.description }}">
+    {% endif %}
+</head>
+```
+
+## Examples
+
+### Dynamic Metadata
+
+```python
+@register_metadata
+class ProductMetadata:
+    title = MetadataField(
+        template="{{product.name}} - Buy Online | {{site.name}}"
+    )
+    description = MetadataField(
+        template="Shop {{product.name}} starting at ${{product.price}}. {{product.short_description}}"
+    )
+
+    def get_context(self, request):
+        return {
+            'product': Product.objects.get(slug=request.path.split('/')[-1])
+        }
+```
+
+### Multilingual SEO
+
+```python
+@register_metadata
+class I18nMetadata:
+    title = MetadataField()
+    description = MetadataField()
+
+    class Meta:
+        use_i18n = True
+        
+    def get_translations(self, language):
+        return {
+            'title': {
+                'en': 'Welcome to our store',
+                'es': 'Bienvenido a nuestra tienda'
+            },
+            'description': {
+                'en': 'Shop the best products online',
+                'es': 'Compra los mejores productos en línea'
+            }
+        }
+```
+
+### Advanced URL Pattern Matching
+
+```python
+from seo_optimizer.models import RedirectPattern
+
+# Redirect old blog URLs to new structure
+RedirectPattern.objects.create(
+    url_pattern="/blog/(\d{4})/(\d{2})/(.+)",
+    redirect_url="/articles/$3",
+    is_regex=True,
+    status_code=301
+)
+```
+
+## Best Practices
+
+### Performance Optimization
+
+1. **Enable Caching:**
+   ```python
+   class Meta:
+       use_cache = True
+       cache_timeout = 3600  # 1 hour
+   ```
+
+2. **Use Async Support** for high-traffic pages:
+   ```python
+   async def get_product_meta(request):
+       return await ProductMetadata.async_get_metadata(request.path)
+   ```
+
+3. **Batch Process** metadata updates:
+   ```python
+   from seo_optimizer.utils import bulk_metadata_update
+   
+   await bulk_metadata_update(ProductMetadata, products)
+   ```
+
+### SEO Guidelines
+
+1. **Title Length:** Keep titles between 50-60 characters
+2. **Description Length:** Aim for 150-160 characters
+3. **Keywords:** Use 5-8 relevant keywords
+4. **Mobile Optimization:** Enable mobile-specific metadata
+5. **URL Structure:** Use clean, descriptive URLs
+6. **Sitemap:** Generate and update regularly
+
+### Security
+
+1. **Sanitize User Input:**
+   ```python
+   from seo_optimizer.utils import sanitize_meta
+   
+   title = sanitize_meta(user_input)
+   ```
+
+2. **API Keys:** Store sensitive data in environment variables
+3. **Rate Limiting:** Enable for metadata API endpoints
+4. **Access Control:** Restrict admin interface access
+
+### Monitoring
+
+1. **Enable Analytics:**
+   ```python
+   SEO_OPTIMIZER = {
+       'ENABLE_ANALYTICS': True,
+       'ANALYTICS_RETENTION': 90  # days
+   }
+   ```
+
+2. **Track Performance:**
+   ```python
+   from seo_optimizer.analytics import track_meta_performance
+   
+   performance_data = await track_meta_performance('/products/')
+   ```
+
+3. **Set Up Alerts** for SEO issues and errors
