+By setting a unique ID, users will have the option to ignore the discovery of your config entry. That way, they won't be bothered about it anymore.
+If the integration uses HomeKit, Zeroconf/mDNS or SSDP/uPnP to be discovered, supplying a unique ID is required.
+
+If a unique ID isn't available, alternatively, the `zerconf`, `homekit`, `ssdp` and `discovery` steps can be omitted, even if they are configured in
+the integration manifest. In that case, the `user` step will be called when the item is discovered.
+
+Alternatively, if an integration can't get a unique ID all the time (e.g., multiple devices, some have one, some don't), a helper is available
+that still allows for discovery, as long as there aren't any instances of the integrations configured yet.
+
+```python
+if device_unique_id:
+  await self.async_set_unique_id(device_unique_id)
+await self._async_handle_discovery_without_unique_id()
+```
