+## Enable infrared
+
+Users who want to enable infrared support, for example for using LIRC (Linux
+Infrared Remote Control), have to explicitly set in local.conf:
+
+    ENABLE_IR = "1"
+
+This will add device tree overlays gpio-ir and gpio-ir-tx to config.txt.
+Appropriate kernel modules will be also included in the image. By default the
+GPIO pin for gpio-ir is set to 18 and the pin for gpio-ir-tx is 17. Both pins
+can be easily changed by modifying variables `GPIO_IR` and `GPIO_IR_TX`.
+
 ## Manual additions to config.txt
 
 The `RPI_EXTRA_CONFIG` variable can be used to manually add additional lines to
