+The **Labs** {% term integration %} provides a dedicated panel where you can preview and test new features before they become standard in Home Assistant. These preview features are fully functional and free of critical bugs, but may still undergo design changes based on user feedback.
+
+Labs preview features are different from beta testing:
+
+- *Beta testing* evaluates the stability of upcoming Home Assistant releases.
+- *Labs preview features* are preview features being refined through real-world usage and feedback.
+
+{% include integrations/config_flow.md %}
