+## Example - Generating conformance results standalone
+
+You can generate conformance results independently of the test suite for analysis or reuse:
+
+```console
+# Generate results and keep binary for reuse
+$ npm run gen:gwc-report
+
+# Generate results with custom name and cleanup binary
+$ npm run gen:gwc-report -- my-test --cleanup
+
+# Use the results in your own code
+$ node -e "
+import { generateConformanceResults } from './dist/src/generate-conformance-report.js';
+import { getReportDetails } from './dist/src/get-report-details.js';
+const result = await generateConformanceResults('custom', { cleanupBinary: true });
+console.log('Report saved to:', result.reportPath);
+const details = await getReportDetails(result.reportPath);
+console.log('Success rate:', details.successRate);
+"
+```
