+You can also use the CLI to manage your configuration:
+
+```bash
+# View current config
+color-tool --get-config
+
+# Update specific keys (e.g., enable swatch by default)
+color-tool --set-config defaults --swatch
+
+# Set output format for desktop mode
+color-tool --set-config desktop output=rgba
+
+# Reset to factory defaults
+color-tool --reset-config
+```
+
+## 🧪 Testing
+
+The project includes a comprehensive test suite that verifies color conversion, configuration loading, and system integrations (clipboard/notifications) using mocks.
+
+To run the tests:
+
+```bash
+./tests/run_tests.sh
+```
+
+The test script creates a temporary isolated environment, so it won't affect your system configuration or active clipboard.
