+My setup uses an HC-SR501 or HC-SR602 sensor, a HC-SR505 should also work.
 
 The usermod uses GPIO13 (D1 mini pin D7) by default for the sensor signal but can be changed in the Usermod settings page.
 [This example page](http://www.esp8266learning.com/wemos-mini-pir-sensor-example.php) describes how to connect the sensor.
 
 Use the potentiometers on the sensor to set the time-delay to the minimum and the sensitivity to about half, or slightly above.
+You can also use usermod's off timer instead of sensor's. In such case rotate the potentiometer to its shortest time possible (or use SR602 which lacks such potentiometer).

+### Configuration options
+
+Usermod can be configured in Usermods settings page.
+
+* `PIRenabled` - enable/disable usermod
+* `pin` - dynamically change GPIO pin where PIR sensor is attached to ESP
+* `PIRoffSec` - number of seconds after PIR sensor deactivates when usermod triggers Off preset (or turns WLED off)
+* `on-preset` - preset triggered when PIR activates (if this is 0 it will just turn WLED on)
+* `off-preset` - preset triggered when PIR deactivates (if this is 0 it will just turn WLED off)
+* `nighttime-only` - enable triggering only between sunset and sunrise (you will need to set up _NTP_, _Lat_ & _Lon_ in Time & Macro settings)
+* `mqtt-only` - only send MQTT messages, do not interact with WLED
+* `off-only` - only trigger presets or turn WLED on/off in WLED is not already on (displaying effect)
+* `notifications` - enable or disable sending notifications to other WLED instances using Sync button
