+
+Integrates MySensors covers into Home Assistant. See the [main component] for configuration instructions.
+
+The following actuator types are supported:
+
+##### MySensors version 1.4
+S_TYPE      | V_TYPE
+------------|-------------
+S_COVER     | V_UP, V_DOWN, V_STOP, [V_DIMMER or V_LIGHT]
+
+##### MySensors version 1.5 and higher
+S_TYPE      | V_TYPE
+------------|-------------
+S_COVER     | V_UP, V_DOWN, V_STOP, [V_PERCENTAGE or V_STATUS]
+
+All V_TYPES above are required. Use V_PERCENTAGE (or V_DIMMER) if you know the exact position of the cover in percent, use V_STATUS (or V_LIGHT) if you don't.
+
+For more information, visit the [serial api] of MySensors.
