+## Summary
+
+The Sensor Rotation behavior triggers a different behavior, depending on whether the sensor is rotated clockwise or counter-clockwise. Two variants of this behavior are available, allowing either fully specifying the
+two behaviors and their parameters together, or allowing binding the sensor rotation with different clockwise and counterclockwise parameters in the keymap itself.
+
+## Sensor Rotation
+
+The standard sensor rotation behavior allows fully binding behaviors to be invoked:
+
+- If rotated clockwise, the first bound behavior is triggered.
+- If rotated counter-clockwise, the second bound behavior is triggered.
+
+### Configuration
+
+Here is an example that binds the [RGB Underglow Behavior](underglow.md) to change the RGB brightness:
+
+```dts
+/ {
+    behaviors {
+        rgb_encoder: rgb_encoder {
+            compatible = "zmk,behavior-sensor-rotate";
+            #sensor-binding-cells = <0>;
+            bindings = <&rgb_ug RGB_BRI>, <&rgb_ug RGB_BRD>;
+        };
+    };
+
+    keymap {
+        compatible = "zmk,keymap";
+
+        base {
+            ...
+            sensor-bindings = <&rgb_encoder>;
+        }
+    };
+};
+```
+
+## Variable Sensor Rotation
+
+The variable sensor rotation behavior is configured with two behaviors that each expect a single parameter,
+allowing the sensor rotation instance to be bound with two parameters at usage time.
+
+- If rotated clockwise, the first bound behavior is triggered with the first parameter passed to the sensor rotation.
+- If rotated counter-clockwise, the second bound behavior is triggered with the second parameter passed to the sensor rotation.
+
+### Configuration
+
+Here is an example, showing how send key presses on rotation:
+
+First, defining the sensor rotation itself, binding the [Key Press Behavior](key-press.md) twice, then binding it in the `sensor-bindings` property of a keymap layer:
+
+```dts
+/ {
+    behaviors {
+        rot_kp: sensor_rotate_kp {
+            compatible = "zmk,behavior-sensor-rotate-var";
+            #sensor-binding-cells = <2>;
+            bindings = <&kp>, <&kp>;
+        };
+    };
+
+    keymap {
+        compatible = "zmk,keymap";
+        base {
+            ...
+            sensor-bindings = <&rot_kp PG_UP PG_DN>;
+        }
+    }
+};
+```
