+## Technical Implementation
+
+The plugin is implemented as a Joomla 5.x system plugin with the following architecture:
+
+### Core Components
+
+* **mokowaasbrand.php** - Main plugin class (`PlgSystemMokoWaaSBrand`) that extends `CMSPlugin`
+* **mokowaasbrand.xml** - Plugin manifest defining metadata, file structure, and configuration parameters
+* **services/provider.php** - Dependency injection service provider for Joomla 5.x container registration
+
+### Event Handlers
+
+The plugin implements the following Joomla system events:
+
+* `onAfterInitialise` - Triggered after framework initialization; provides hook for branding logic
+* `onAfterRoute` - Triggered after route determination; allows additional branding adjustments
+
+### Language Override Integration
+
+The plugin integrates with Joomla's native language override system:
+
+* Language overrides in `language/overrides/` (frontend)
+* Administrator overrides in `administrator/language/overrides/`
+* Joomla automatically loads these overrides without programmatic intervention
+* Plugin provides the framework while Joomla handles the actual string substitution
+
+### Configuration Options
+
+The plugin exposes the following configuration parameters:
+
+* **Enable Branding** - Toggle to enable/disable all branding functionality (default: enabled)
+
+### Namespace and Autoloading
+
+Uses Joomla 5.x namespace: `Moko\Plugin\System\MokoWaaSBrand` with PSR-4 autoloading through the service provider.
