 This driver adds support to wirelessly control blinds and roller shades connected to regular ON/OFF motors or stepper motors.
 
+To use this feature, you must compile your own firmware binary. Use any of the [available compilation methods](https://github.com/arendst/Sonoff-Tasmota/wiki/Flashing#flashing-and-compiling-from-source) you prefer. Add the following compiler directives to `user_config_override.h`:
+```
+#ifndef USE_SHUTTER
+#define USE_SHUTTER      //  (+6k code)
+#endif
+```
+
 The device must have at least two relays (e.g., a [Sonoff Dual R2](#sonoff-dual-r2-required-configuration)). Otherwise the shutter feature will not work.
