+# Midea AC Binding
+
+This binding integrates Air Conditioners that use the Midea protocol. Midea is an OEM for many brands.
+
+An AC device is likely supported if it uses one of the following Android apps or it's iOS equivalent.
+
+| Application                                  | Comment                               | Options      |
+|--:-------------------------------------------|--:------------------------------------|--------------|
+| Midea Air (com.midea.aircondition.obm)       | Full Support of key and token updates | Midea Air    |
+| NetHome Plus (com.midea.aircondition)        | Full Support of key and token updates | NetHome Plus |
+| SmartHome/MSmartHome (com.midea.ai.overseas) | Full Support of key and token updates | MSmartHome   |
+
+Note: The Air Conditioner must already be set-up on the WiFi network and have a fixed IP Address with one of the three apps listed above for full discovery and key and token updates.
+
+## Supported Things
+
+This binding supports one Thing type `ac`.
+
+## Discovery
+
+Once the Air Conditioner is on the network (WiFi active) the other required parameters can be discovered automatically.
+An IP broadcast message is sent and every responding unit gets added to the Inbox.
+As an alternative use the python application msmart-ng from <https://github.com/mill1000/midea-msmart> with the msmart-ng discover ipAddress option.
+
+## Binding Configuration
+
+No binding configuration is required.
