+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is the **Smartling Connector** WordPress plugin - a translation and localization platform integration that seamlessly translates WordPress content through the Smartling API. The plugin handles content upload, translation management, and automatic download of completed translations.
+
+## Key Development Commands
+
+### Testing
+- **Unit tests**: `./inc/third-party/phpunit/phpunit/phpunit --configuration ./phpunit.xml.dist`
+
+### Build & Release
+- **Build plugin**: `./build.sh` - Creates production-ready `smartling-connector.zip`
+- **Composer dependencies**: `./composer update` (dev), `./composer update --no-dev` (production)
+
+### Dependency Management
+- Dependencies are installed to `inc/third-party/` (configured in composer.json)
+- Scoped namespacing prevents conflicts with other WordPress plugins, installed to `inc/lib/` (https://github.com/vsolovei-smartling/namespacer)
+
+## Architecture Overview
+
+### Core Components
+
+**Bootstrap Process** (`inc/Smartling/Bootstrap.php`):
+- Main entry point that initializes the plugin
+- Handles dependency injection container setup
+- Registers WordPress hooks and services
+- Manages plugin activation/deactivation
+
+**Content Management**:
+- `ContentTypes/` - Handles different WordPress content types (posts, pages, taxonomies, menus, widgets)
+- `ExternalContent*` - Specialized handlers for third-party plugins (Elementor, Yoast, ACF, Gravity Forms, Beaver Builder)
+- `Submissions/` - Core translation workflow management
+
+**Translation Pipeline**:
+1. **Upload**: Content serialization → Smartling API upload
+2. **Processing**: Translation occurs in Smartling dashboard  
+3. **Download**: Completed translations → WordPress content application
+
+**Key Services**:
+- `ApiWrapper` - Smartling API communication layer with retry logic
+- `SubmissionManager` - Translation job lifecycle management
+- `ContentHelper` - WordPress content serialization/deserialization
+- `FieldsFilterHelper` - Field filtering and transformation rules
+
+### Database Layer
+- `DbAl/` - Database abstraction layer
+- `Migrations/` - Schema versioning and updates
+- `WordpressContentEntities/` - WordPress-specific entity handling
+
+### Extensibility
+- `Extensions/` - Plugin extension system for third-party integrations
+- `Tuner/` - Content filtering and rule management
+- `Replacers/` - Content transformation during translation
+
+## Testing Structure
+
+**Unit Tests** (`tests/`):
+- Test individual components in isolation
+- Mock dependencies for fast execution
+- Run with: `./inc/third-party/phpunit/phpunit/phpunit --configuration ./phpunit.xml.dist`
+
+**Integration Tests** (`tests/IntegrationTests/`):
+- Full WordPress environment testing
+- Real database operations
+- Third-party plugin compatibility testing
+- Run with: `phpunit -c tests/phpunit.xml`
+
+**Docker Testing**:
+- Complete isolated environment with MySQL
+- Automated via `Buildplan/test.sh`
+- Includes WordPress multisite configuration
+
+## Configuration
+
+**Service Configuration** (`inc/config/`):
+- `services.yml` - Dependency injection container setup
+- `boot.yml` - Bootstrap configuration
+- `field-processor.yml` - Content processing rules
+- `media-attachment-rules.yml` - Media handling rules
+
+**Key Settings**:
+- Content type auto-discovery
+- Field filtering rules
+- Translation workflow configuration
+- Third-party plugin integration settings
+
+## Development Guidelines
+
+### Code Structure
+- PSR-0 autoloading with `Smartling\` namespace
+- Dependency injection throughout the codebase
+- Extensive use of interfaces for testability
+- WordPress hooks for extensibility
+
+### Content Processing
+- All content goes through serialization/deserialization pipeline
+- Field-level filtering for translation control
+- Relationship tracking between original and translated content
+- Gutenberg block-level translation support
+
+### API Integration
+- Robust error handling and retry mechanisms
+- Job-based translation workflow
+- Progress tracking and status reporting
+- Webhook support for real-time updates
+
+### Third-party Compatibility  
+- Modular extension system for popular WordPress plugins
+- Page builder support (Elementor, Beaver Builder)
+- SEO plugin integration (Yoast, All in One SEO)
+- Form plugin support (Gravity Forms)
+- Advanced Custom Fields (ACF) support
+
+## Common Workflows
+
+When working on content type support, examine existing `ContentTypes/` implementations. For API changes, check both `ApiWrapper` and related tests. For field processing modifications, review `FieldsFilterHelper` and corresponding configuration files.
+
+### Elementor Widget Development
+
+When adding or modifying Elementor widget support, refer to the comprehensive guide:
+- **Elementor Development Guide**: `docs/ELEMENTOR_DEVELOPMENT.md`
+- Contains patterns for processing related content, testing strategies, and real-world examples
+- Essential reading for WP-* tickets involving Elementor widgets
