+Run the coverage script (excludes main package):
+
+```bash
+./scripts/coverage.sh
+```
+
+The project maintains over 78% test coverage across the core packages, which helps ensure reliability and stability. The coverage includes:
+
+- API Client: 73.3% covered
+- Config Management: 85.4% covered
+- Export Functionality: 78.3% covered
+- Internationalization: 81.6% covered
+- Logging System: 97.7% covered
+
+### Code Coverage Configuration
+
+The project includes a `.codecov.yml` file that configures code coverage analysis for CI/CD pipelines. This configuration:
+
+- Sets a 70% coverage threshold for the project
+- Excludes the `cmd/export_trakt` directory (main package) from coverage calculations
+- Provides detailed coverage reports for each pull request
+
+If you're using GitHub Actions or another CI system, this configuration ensures accurate coverage reporting focused on the core packages rather than the main application entry point.
